Ammonia Fitting of Multiple Velocity Components in High-Mass Star-Forming Regions
T. Withers, S. Sadavoy, M. Chen +19
We perform a multiple velocity component analysis of ammonia (NH) gas from KEYSTONE, a Green Bank Telescope survey covering 11 giant molecular clouds (GMCs) at distances from 0…
The Green Bank Ammonia Survey: Data Release 2
Jaime E. Pineda, Rachel K. Friesen, Erik Rosolowsky +22
We present an overview of the final data release (DR2) from the Green Bank Ammonia Survey (GAS). GAS is a Large Program at the Green Bank Telescope to map all Gould Belt star-formi…
Filament Accretion and Fragmentation in the Perseus Molecular Cloud
Michael Chun-Yuan Chen, James Di Francesco, Rachel K. Friesen +6
Observations suggest that filaments in molecular clouds can grow by mass accretion while forming cores via fragmentation. Here we present one of the first large sample studies of f…
The Next Generation Very Large Array
James Di Francesco, Dean Chalmers, Nolan Denman +17
The next generation Very Large Array (ngVLA) is a transformational radio observatory being designed by the U.S. National Radio Astronomy Observatory (NRAO). It will provide order o…
ALMA Observations of Starless Core Substructure in Ophiuchus
Helen Kirk, Michael M. Dunham, James Di Francesco +11
Compact substructure is expected to arise in a starless core as mass becomes concentrated in the central region likely to form a protostar. Additionally, multiple peaks may form if…
An analysis of the deuterium fractionation of star-forming cores in the Perseus molecular cloud
Rachel Friesen, Helen Kirk, Yancy Shirley
We have performed a pointed survey of N2D+ 2-1 and N2D+ 3-2 emission toward 64 N2H+-bright starless and protostellar cores in the Perseus molecular cloud using the Arizona Radio Ob…
