The Galactic Center Molecular Cloud Survey. I. A Steep Linewidth-Size Relation & Suppression of Star Formation
Jens Kauffmann, Thushara Pillai, Qizhou Zhang +4
The Central Molecular Zone (CMZ; inner ) of the Milky Way is a star formation (SF) environment with very extreme physical properties. Exploration of SF in this r…
Dense core properties in the Infrared Dark cloud G14.225-0.506 revealed by ALMA
Satoshi Ohashi, Patricio Sanhueza, Huei-Ru Vivien Chen +5
We have performed a dense core survey toward the Infrared Dark Cloud G14.225-0.506 at 3 mm continuum emission with the Atacama Large Millimeter/Submillimeter Array (ALMA). This sur…
The Galactic Center Molecular Cloud Survey. II. A Lack of Dense Gas & Cloud Evolution along Galactic Center Orbits
Jens Kauffmann, Thushara Pillai, Qizhou Zhang +5
We present the first systematic study of the density structure of clouds found in a complete sample covering all major molecular clouds in the Central Molecular Zone (CMZ; inner $\…
880 m SMA polarization observations of the quasar 3C 286
Charles L. H. Hull, Josep M. Girart, Qizhou Zhang
For decades, the bright radio quasar 3C 286 has been widely recognized as one of the most reliable polarization calibrators at centimeter wavelengths because of its unchanging pola…
Deeply Embedded Protostellar Population in the Central Molecular Zone Suggested by HO Masers and Dense Cores
Xing Lu, Qizhou Zhang, Jens Kauffmann +4
The Central Molecular Zone (CMZ), usually referring to the inner 500 pc of the Galaxy, contains a dozen of massive ( ) molecular clouds. Are these clouds going t…
Magnetically Dominated Parallel Interstellar Filaments at the Infrared Dark Cloud G14.225-0.506
Fabio P. Santos, Gemma Busquet, Gabriel A. P. Franco +2
The G14.225-0.506 infrared dark cloud (IRDC G14.2) displays a remarkable complex of parallel dense molecular filaments projected on the plane of the sky. Previous dust emission and…
The formation of ethylene glycol and other complex organic molecules in star-forming regions
V. M. Rivilla, M. T. Beltrán, R. Cesaroni +3
We study the molecular abundance and spatial distribution of the simplest sugar alcohol, ethylene glycol (EG), the simplest sugar glycoladehyde (GA), and other chemically related c…
The structure and early evolution of massive star forming regions - Substructure in the infrared dark cloud SDC13
Catherine McGuire, Gary Fuller, Nicolas Peretto +4
Investigations into the substructure of massive star forming regions are essential for understanding the observed relationships between core mass distributions and mass distributio…
Outflow detection in a 70 m dark high-mass core
S. Feng, H. Beuther, Q. Zhang +4
We present observations towards a high-mass (), low luminosity () m dark molecular core G 28.34 S-A at 3.4 mm, using the IRAM 30…
Star formation laws in both Galactic massive clumps and external galaxies: An extensive study with dust continuum, HCN (4-3), and CS (7-6)
Tie Liu, Kee-Tae Kim, Hyunju Yoo +20
We observed 146 Galactic clumps in HCN (4-3) and CS (7-6) with the Atacama Submillimeter Telescope Experiment (ASTE) 10-m telescope. A tight linear relationship between star format…
Are Infrared Dark Clouds Really Quiescent?
S. Feng, H. Beuther, Q. Zhang +4
The dense, cold regions where high-mass stars form are poorly characterised, yet they represent an ideal opportunity to learn more about the initial conditions of high-mass star fo…
What is controlling the fragmentation process in the Infrared Dark Cloud G14.225-0.506? Differet level of fragmentation in twin hubs
G. Busquet, R. Estalella, A. Palau +7
We present observations of the 1.3 mm continuum emission toward hub-N and hub-S of the infrared dark cloud G14.225-0.506 carried out with the Submillimeter Array, together with obs…
