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…

RAMPS Data

The Radio Ammonia Mid-Plane Survey (RAMPS) is a large international project that surveys 24 degrees2 of the Galactic Plane using the Green Bank Telescope (GBT). These observations survey the Galactic Plane in the northern hemisphere from 10o<= l <= 40o and b = |0.4o| in ammonia and water masers. Legacy Data Details about the reduction…
