MUSTANG1 CLASH Data
The goal was to observe the 21 (those observable from Green Bank) of the 25 CLASH clusters with MUSTANG1. 13 CLASH clusters were observed and the resulting data products are provided here. Acknowledgement For publications that make use of these data please cite Romero et al. 2015 and Romero et al. 2017. Please also acknowledge…

GBT at 3/4 azimuth Slew Rate
Three more azimuth wheels have been replaced during this summer maintenance period. Wheel inspection shows no advanced signs of fatigue in the remaining wheels. The restriction to 1/2 azimuth slew rate has been lifted and the GBT is now moving at 3/4 azimuth slew rate.

Massive Stars Born from Violent Cosmic Collapse
Astronomers using the U.S. National Science Foundation Green Bank Telescope reveal new process of star formation, challenging existing models Controlled chaos is a key part of forming massive stars. An international team of astronomers has observed evidence that massive stars can be born from rapidly collapsing clouds of gas and dust, challenging long-held assumptions about…

Telescope Tag-Team Discovers Galactic Cluster’s Bizarre Secrets
Towards the center of our Milky Way Galaxy, in the constellation Sagittarius, astronomers have discovered 10 monstrous neutron stars. Astronomers already knew that 39 pulsars call Terzan 5 home. With the teamwork of the U.S. National Science Foundation Green Bank Telescope (NSF GBT) and the South African Radio Astronomy Observatory’s MeerKAT Telescope, ten more have…

HI-MaNGA Data
HI-MaNGA is a 21cm follow-up program for the SDSS-IV MaNGA survey, a survey of 10,010 unique galaxies with an Integral Field Unit (for resolved optical spectroscopy). The primary goal of HI-MaNGA is to observe all z<0.05 MaNGA galaxies with the Green Bank Telescope which lack HI data from other sources. Acknowledgement For publications that make use…

DiSCo Data (pending)
Dynamics in Star-forming Cores The DiSCo survey will address a key open question in star formation: the origin and distribution of angular momenta of star-forming cores. Our broad statistical approach is essential to understanding the range of intrinsic behavior, the statistically most common behaviors, and how those behaviors correlate with stellar outcome and environment. By…
