Rotating filament in Orion B: Do cores inherit their angular momentum from their parent filament?
Cheng-Han Hsieh, Héctor G. Arce, Diego Mardones +2
Angular momentum is one of the most important physical quantities that govern star formation. The initial angular momentum of a core may be responsible for its fragmentation and ca…
ALMA observations of envelopes around first hydrostatic core candidates
Maria Jose Maureira, Hector G. Arce, Michael M. Dunham +4
We present ALMA 3 mm molecular line and continuum observations with a resolution of ~3.5" towards five first hydrostatic core (FHSC) candidates (L1451-mm, Per-bolo 58, Per-bolo 45,…
ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions -- I. Survey description and a first look at G9.62+0.19
Tie Liu, Neal J. Evans, Kee-Tae Kim +41
The "ATOMS," standing for {\it ALMA Three-millimeter Observations of Massive Star-forming regions}, survey has observed 146 active star forming regions with ALMA Band 3, aiming to…
Filament Intersections and Cold Dense Cores in Orion A North
Chao Zhang, Zhiyuan Ren, Jingwen Wu +13
We studied the filament structures and dense cores in OMC-2,3 region in Orion A North molecular cloud using the high-resolution N2H+ (1-0) spectral cube observed with the Atacama L…
Resolution-dependent Subsonic Non-thermal Line Dispersion Revealed by ALMA
Nannan Yue, Di Li, Qizhou Zhang +4
We report here Atacama Large Millimeter/submillimeter Array (ALMA) NH (1-0) images of the Orion Molecular Cloud 2 and 3 (OMC-2/3) with high angular resolution (3'' or 1200…
ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions -- II. Compact objects in ACA observations and star formation scaling relations
Tie Liu, Neal J. Evans, Kee-Tae Kim +40
We report studies of the relationships between the total bolometric luminosity ( or ) and the molecular line luminosities of transitions of H$^{13…
