CO multi-line observations of HH 80-81: a two-component molecular outflow associated with the largest protostellar jet in our Galaxy
Keping Qiu, Friedrich Wyrowski, Karl Menten +2
Stretching a length reaching 10 pc projected in the plane of sky, the radio jet associated with Herbig-Haro objects 80 and 81 (HH 80-81) is known as the largest and best collimated…
Compressed magnetic field in the magnetically-regulated global collapsing clump of G9.62+0.19
Tie Liu, Kee-Tae Kim, Sheng-Yuan Liu +22
How stellar feedback from high-mass stars (e.g., H{\sc ii} regions) influences the surrounding interstellar medium and regulates new star formation is still unclear. To address thi…
G337.342-0.119 (the "Pebble"): A Cold, Dense, High-Mass Molecular Cloud with Unusually Large Linewidths and a Candidate High-Mass Star Cluster Progenitor
James M. Jackson, Yanett Contreras, Jill M. Rathborne +7
Exactly how high-mass star clusters form, especially the young massive clusters (YMCs: age Myr; mass solar masses), remains an open problem, largely because they are…
SMA Observations of Extended Emission in Interacting Galaxy NGC 3627
Charles J. Law, Qizhou Zhang, Luca Ricci +5
We present moderate () and high angular resolution () observations of emission toward nearby, interacting ga…
Interactions between Gas Dynamics and Magnetic Fields in the Massive Dense Cores of the DR21 Filament
Tao-Chung Ching, Shih-Ping Lai, Qizhou Zhang +3
We report Submillimeter Array molecular line observations in the 345 GHz band of five massive dense cores, Cyg-N38, Cyg-N43, Cyg-N48, Cyg-N51, and Cyg-N53 in the DR21 filament. The…
Investigating fragmentation of gas structures in OB cluster-forming molecular clump G33.92+0.11 with 1000 AU resolution observations of ALMA
Hauyu Baobab Liu, Huei-Ru Vivien Chen, Carlos G. Román-Zúñiga +7
We report new, 1000 AU spatial resolution observations of 225 GHz dust continuum emission towards the OB cluster-forming molecular clump G33.92+0.11. On parsec scales, this m…
ALMA observations of the very young Class 0 protostellar system HH 211-mms: a 30-au dusty disk with a disk-wind traced by SO?
Chin-Fei Lee, Zhi-Yun Li, Naomi Hirano +3
HH 211-mms is one of the youngest Class 0 protostellar systems in Perseus at ~ 235 pc away. We have mapped its central region at up to ~ 7 AU (0.03") resolution. A dusty disk is se…
Detecting Infall in High-Mass Protostellar Objects
Maria T. Beltrán, Qizhou Zhang, Víctor M. Rivilla
The role of accretion disks in the formation of low-mass stars has been well assessed by means of high angular resolution observations at various wavelengths. These findings confir…
Infall Signatures in a Prestellar Core embedded in the High-Mass 70 m Dark IRDC G331.372-00.116
Yanett Contreras, Patricio Sanhueza, James M. Jackson +14
Using Galactic Plane surveys, we have selected a massive (1200 M), cold (14 K) 3.6-70 m dark IRDC G331.372-00.116. This IRDC has the potential to form high-mass stars an…
Fragmentation and disk formation during high-mass star formation: The IRAM NOEMA (Northern Extended Millimeter Array) large program CORE
H. Beuther, J. C. Mottram, A. Ahmadi +30
Aims: We aim to understand the fragmentation as well as the disk formation, outflow generation and chemical processes during high-mass star formation on spatial scales of individua…
Multi-directional mass-accretion and collimated outflows in W51
Ciriaco Goddi, Adam Ginsburg, Luke Maud +2
We observed the W51 high-mass star-forming complex with ALMA's longest-baseline configurations, achieving an angular resolution of 20 milliarcseconds, corresponding to a line…
Radiative transfer modelling of W33A MM1: 3-D structure and dynamics of a complex massive star forming region
Andrés F. Izquierdo, Roberto Galván-Madrid, Luke T. Maud +5
We present a composite model and radiative transfer simulations of the massive star forming core W33A MM1. The model was tailored to reproduce the complex features observed with AL…
SMA observations of the polarized dust emission in solar-type Class 0 protostars: the magnetic field properties at envelope scales
Maud Galametz, Anaelle Maury, Josep M. Girart +6
Although, from a theoretical point of view, magnetic fields are believed to have a significant role during the early stages of star formation, especially during the main accretion…
Detection of Dust Condensations in the Orion Bar Photon-dominated Region
Keping Qiu, Zeqiang Xie, Qizhou Zhang
We report Submillimeter Array dust continuum and molecular spectral line observations toward the Orion Bar photon-dominated region (PDR). The 1.2 mm continuum map reveals, for the…
