Cannan Huey-You, just 11 years old, impressed professional astronomers in January with his research on a massive intergalactic gas cloud.
When astronomers and astrophysicists descended on Grapevine, Texas, this past January for the semiannual conference that many call the “Super Bowl of Astronomy,” they were joined by the meeting’s youngest participant ever.
On Friday, 11-year-old Cannan Huey-You walked up to his poster and described research on the object known as Complex A, a massive gas cloud destined to crash into the Milky Way.

Welcome to the first issue of The Observer, the Green Bank Observatory’s quarterly newsletter. As many of you are aware, after almost 60 years in the National Radio Astronomy Observatory, we have branched off to become a separate organization – the Green Bank Observatory. While the separation entails many changes for the facility and staff, we are endeavoring to keep the changes as smooth as possible for our user community. As a result, the proposal process for the GBT will remain synchronized with that of our sister organizations the NRAO and the Long Baseline Observatory. Many of the other changes we are undergoing, such as the website transition, are described within this newsletter.
2016 was a busy year for the Green Bank Observatory. In addition to transitioning to a separate organization, we have two new high frequency instruments coming online this winter – MUSTANG2, a 70-105 GHz, 210 element bolometer array, and ARGUS, a 75-116 GHz, 16 element focal plane array. Both instruments have been through their initial science commissioning and are already taking early science data. Also in 2016 we began two exciting new contracts with the Breakthrough Foundation and with NANOGrav. Breakthrough Listen is the largest ever scientific research program aimed at finding evidence of civilizations beyond Earth. The scope and power of the search are on an unprecedented scale – the program includes a survey of the 1,000,000 closest stars to Earth. It scans the center of our galaxy and the entire galactic plane. Beyond the Milky Way, it listens for messages from the 100 closest galaxies to ours. NANOGrav monitors a set of pulsars that together form a Galactic scale gravitational-wave observatory. The data collected is also used to study supermassive black hole binaries in order to understand the morphology, kinematics, gas content, and feedback mechanisms of galaxies.
In the next few months we will be seeing quite a few improvements to the Green Bank Observatory. This winter will be our first excellent season for high frequency observing with ARGUS and MUSTANG2. Additionally, the first few pulsar observing modes with VEGAS, our FPGA/GPU signal processing system, will be released. And over the next few months we will be releasing a new reservations system for visitors coming to the site.
Finally, I am excited to announce that this fall we will be having both a celebration of 60 years as a world class astronomical facility and a workshop looking toward the long term future of our facility and its instruments. Information on the workshop is given later in this newsletter, and information on the 60th anniversary celebration will be forthcoming.
Wishing all of you a fantastic 2017,
Green Bank Observatory Director
Observer Training Workshop (May 15-19)
The Green Bank Observatory’s Observer training schools provide an introduction to general radio astronomical techniques as well as onsite training for GBT observers. These training schools will replace the single-dish summer schools which have held in the past, and will be scheduled two to three times each year. The next training school will be held May 15-19, 2017 in Green Bank, with the following school September 18-22, 2017.
We still encourage new observers to visit the Observatory, where their projects will receive priority scheduling and where local staff are on hand to assist in the observations. For further information, please see:

Green Bank Telescope Time Allocation for Semester 17b
The Green Bank Observatory (GBO) invites scientists to participate in the GBO’s 2017B Semester Call for Proposals for the Green Bank Telescope (GBT). Proposals requesting the GBT as part of High Sensitivity Array (HSA), and Global 3mm VLBI Array (GMVA) should be submitted through the Long Baseline Observatory’s call (available here).
The submission deadline for Semester 2017B proposals is Wednesday, 1 February 2017, at 17:00 EST (22:00 UTC).
The GBO wishes to remind proposers of continuing opportunities for joint observations with the Chandra X-ray Observatory, the Hubble Space Telescope, the Swift Gamma-Ray Burst Mission and the Fermi Gamma-ray Space Telescope.
The GBO strongly encourages proposers to carefully read through the News and Opportunities section of the proposal as there have been a number of changes made to instrument availability.
Proposal preparation and submission remain via the NRAO Proposal Submission Tool (PST) available at NRAO Interactive Services. Note that the PST use requires registration. Proposers who need assistance with proposal preparation or have questions regarding the Call or GBT capabilities should contact Observatory staff via the Helpdesk.
A Wide Range of Black Hole Masses in Spiral Galaxies
Many spiral galaxies have circumnuclear accretion disks whose properties can be determined through observations of H2O megamasers. The Green Bank Telescope has been systematically discovering such accretion disks, and through participation in VLBI network observations, measuring the mass of the central black hole. Black hole masses derived this way can be extremely accurate, with uncertainties at the level of 5% to 10%, and follow from Keplerian rotation of the accretion disk at radii of 0.2-1 pc.
Green et al (2016) have used the results of this work for spiral galaxies to consider the connection, if any, between galaxy properties and the mass of the central black hole. They conclude that no galaxy property correlates tightly with the mass of the black hole as traced by megamaser disks in L* spiral galaxies.
They find that megamaser disk galaxies have a MBH-sigma* relationship that differs significantly from that established for the early-type galaxies. At a given sigma*, the disk galaxies have significantly smaller black hole masses, with a larger scatter, than the early-type galaxies.
The disk galaxy properties like total mass and central velocity dispersion also lie within a much narrower range than the black hole masses. It appears that the relationship between nuclear black hole mass and other properties of late-type galaxies remains to be understood.

MUSTANG 2: an extremely sensitive, 100 ghz bolometer array
The performance of the newly completed MUSTANG-2 bolometer camera has been verified on the 100-meter Green Bank Telescope and astronomical observations have begun.
MUSTANG-2 sensitively maps broad-spectrum emission on the sky in the 70 to 105 GHz range using 210 individual bolometric detectors, each coupled to the sky with its own feed horn. It will be used for many different types of astronomical studies ranging from detailed imaging of galaxy clusters in the early universe to mapping areas of star formation in our own Galaxy. MUSTANG-2 is the successor to the GBT’s pathfinder 3mm bolometer camera, MUSTANG, and represents a large step forward in sensitivity, fidelity, and robustness. To verify the performance of MUSTANG-2 the instrument team spent 40 minutes mapping a region of star formation in the Orion nebula that had previously been studied by MUSTANG (a press release on the original MUSTANG result can be found here). The new and old maps are very similar even though the old map required over 20 times more telescope time to acquire. Nearly 230 hours of highly-oversubscribed hours of GBT 3mm observing time have been allocated for MUSTANG-2 observing in the 2016/2017 season.
The receiver was developed by a collaboration consisting of the University of Pennsylvania, NRAO, NIST, the University of Michigan, the University of Kwazulu-Natal, and Cardiff University, with support from the NSF’s ATI program.
In December, the Green Bank Science Center hosted our 4th Annual Pocahontas County Science Fair. What a fun day for everyone! We had over 40 volunteers from GBO staff, the Forest Service and the local schools serve as judges and activity leaders. This year, 104 students entered 79 group and individual projects! Students not only competed for top project awards, but enjoyed a day of science and engineering activities. In the star lab, activity leaders challenged students to build a bridge that could hold weight with nothing more than index cards. In the classroom, students designed and built their own robot that could replicate similar scribbles made by our top-secret prototype scribblebot. In another collaborative activity, students moved a small ball from one can to another-using only strings! Being a judge this year was no easy task with so many creative and well-designed projects, however, the top prizes went to some very deserving students.
The top overall winners were: Willie O’Ganian from GBEMS in the elementary competition with “Give Primates a Hand!”, Jaryd Friel from Marlinton Middle School in the middle school division with “Cleaning Coins”, and Pocahontas County High School student Abram Leyzorek won in the high school division with “The effect of Microwaved Water on Feed Corn Growth”.
16 Element Focal Plane Array, ARGUS
Argus is a new 16-element 75-116 GHz focal plane array instrument installed on the GBT. The instrument has successfully completed its initial phases of commissioning and is ready for shared-risk science observations with the GBT.
The image is the result of an early test map taken using all 16 beams of Argus.
The image shows the integrated emission from the 13CO molecule associated with the star-formation region DR21.
This 10’x3’ map required about 40 minutes of telescope time and was taken in non-optimal weather conditions (zenith opacity of 0.42). The image is the result of the default data processing without any data editing. The beam size of the GBT is shown in white at the lower-right of the image for comparison.
Argus is a collaboration between Stanford University (PI Sarah Church), Caltech, JPL, University of Maryland, Universtiy of Miami, and the Green Bank Observatory. Information about the instrument can be found on the ARGUS web-page.
Boy Scout Merit Badge Weekends
Our new Boy Scout Merit Badge Weekends received such a positive response, the event has become a monthly offering for 2017!
Often reserved months in advance, scout groups of all ages book their weekend here in Green Bank, earning their badges in astronomy or electronics. Scouts learn constellations in the star lab, use the 40-ft Telescope to perform a hands-on research experiment, investigate radio frequency interference and learn about motion of stars and planets. Each weekend, the science center hosts up to 60 or more scouts, often from several troops for the program.

As many of you are likely aware, the Green Bank Observatory has a new website, greenbankobservatory.org
The new website will provide all information about the Observatory, from science news through educational events. However, transitioning to the new website will take time. As a result, you will find that much of the material relevant to scientists interested in taking scientific data with the Green Bank Telescope still resides at its former web address:
As content is migrated, the links will be updated to reflect the new web addresses.
John Findlay’s Golf Story
John Findlay, NRAO’s first head of engineering and electronic design, supervised the construction of the 300-foot telescope during 1961-62. He recounts the 300-foot construction project in a paper he gave at the 300-foot 25th birthday celebration in September 1987, which is reprinted in “But it was Fun”, page 145.
The contractor that built the telescope was Bristol Steel and Iron, of Bristol, Virginia. Findlay made frequent trips to Bristol to review the project and disuss changes. The head of BS&I, Jim Tilley, made sure the meetings ended at 12:30 so they could play golf in the afternoon.
Findlay recalls a plan he made for the opening ceremony of the 300-foot telescope:
“Since we are telling stories, I told you that we had to play golf every day we went to Bristol when we were building [the 300 Foot]. And Jim Tilley was not a very good golfer and he had never made a hole-in-one …
I took a nine-iron to the 300 Foot to see if I could hit a ball high enough to get it into the dish. If I had been able to do so I would have offered Jim the opportunity of making a hole-in-one. If this had worked then at the opening ceremony I would have allowed the golf ball to run down the dish and fall through the hole in the middle and with any luck break some small receptacle containing an alcoholic liquid and that would have completed the circuit. But I couldn’t hit a ball into the dish! “

A Full Complement of Post Docs
The Green Bank Scientific division has employed a full complement of Post Docs. Our three Post Docs Nichol Cunningham, Jennifer Weston and Natalia Lewandowska are quickly settling into their roles as part of the Scientific team by coordinating colloquia, working with visiting student groups, supporting the GBT observers and doing their own research.
Nichol is from the United Kingdom and a scholar from Leeds University started at the GB site in September 2015. Nichol has already been a prominent addition to Rec Board by being the official party organizer for the Spring Party, organizing the Post Doc Symposium and coordinating volunteers for the Space Race Rumpus. Nichol’s research is focused on star and galaxy formations.
Jennifer arrived in March after finishing her PhD at Columbia University. Jennifer too has joined the Rec Board and taught during the Research Student Boot Camp. Her research is focused on using radio observations of novae and symbiotic systems to examine the evolution of accreting dwarf galaxies among other things.
Natalia is our newest arrival just joining us in April. She came directly from defending her PhD in Germany at the University of Wurzburg. Natalia’s research is focused on the study of giant radio pulses. Natalia just returned from a conference at the VLA and will be settling into her new role in Green Bank.

Spring 2017 GBT Observer Training Workshop
May 15 – 19, 2017, Green Bank Observatory
The GBT Observer Training Workshop will provide the essential skills and knowledge that observers need to maximize the scientific output of
their use of the Green Bank Telescope. After completing the workshop, attendees will be certified to remotely observe with GBT. The workshop will consist of classroom lectures that provide background on observing techniques with the GBT and single dish radio telescopes more generally, as well as hands-on use of the GBT under the guidance of observatory staff. Topics to be covered include radio telescope fundamentals, observing and calibration techniques, the impact of weather, the GBT observing procedure and software, data reduction, remote observing, telescope scheduling, and remote observing.
Attendees will perform group observing projects that are representative of the observing techniques most relevant to their areas of interest
(e.g. high frequency mapp, continuum, pulsar, etc.).
These workshops will be held twice a year and will complement traditional on-site training.
The workshop will begin on May 15 and end on May 19, 2017. Attendees should plan on arriving in Green Bank on May 14 and departing May 20.
A detailed schedule is forthcoming. For reference, the Fall 2016 schedule is available here.
