Hierarchical fragmentation in the Perseus molecular cloud: From the cloud scale to protostellar objects
Riwaj Pokhrel, Philip C. Myers, Michael M. Dunham +8
We present a study of hierarchical structure in the Perseus molecular cloud, from the scale of the entire cloud (10 pc) to smaller clumps (1 pc), cores (0.05-0…
Assessing the Performance of a Machine Learning Algorithm in Identifying Bubbles in Dust Emission
Duo Xu, Stella S. R. Offner
Stellar feedback created by radiation and winds from massive stars plays a significant role in both physical and chemical evolution of molecular clouds. This energy and momentum le…
The Green Bank Ammonia Survey: Observations of Hierarchical Dense Gas Structures in Cepheus-L1251
Jared Keown, James Di Francesco, Helen Kirk +20
We use Green Bank Ammonia Survey observations of NH (1,1) and (2,2) emission with 32'' FWHM resolution from a ~ 10 pc portion of the Cepheus-L1251 molecular cloud to iden…
A turbulent origin for the complex envelope kinematics in the young low-mass core Per-Bolo 58
Maria Jose Maureira, Hector G. Arce, Stella S. R. Offner +5
We use CARMA 3mm continuum and molecular lines (NH2D, N2H+, HCO+, HCN and CS) at ~1000 au resolution to characterize the structure and kinematics of the envelope surrounding the de…
Impact of Protostellar Outflows on Turbulence and Star Formation Efficiency in Magnetized Dense Cores
Stella S. R. Offner, Jonah Chaban
The star-forming efficiency of dense gas is thought to be set within cores by outflow and radiative feedback. We use magneto-hydrodynamic simulations to investigate the relation be…
The Green Bank Ammonia Survey: Dense Cores Under Pressure in Orion A
Helen Kirk, Rachel K. Friesen, Jaime E. Pineda +21
We use gas temperature and velocity dispersion data from the Green Bank Ammonia Survey and core masses and sizes from the James Clerk Maxwell Telescope Gould Belt Survey to estimat…
