ALMA Observations of Supernova Remnant N49 in the Large Magellanic Cloud. II. Non-LTE Analysis of Shock-heated Molecular Clouds
H. Sano, Y. Yamane, J. Th. van Loon +28
We present the first compelling evidence of shock-heated molecular clouds associated with the supernova remnant (SNR) N49 in the Large Magellanic Cloud (LMC). Using CO( =…
Massive star formation in the Carina nebula complex and Gum 31 -- II. a cloud-cloud collision in Gum 31
Shinji Fujita, Hidetoshi Sano, Rei Enokiya +10
We present the results of analyses of the 12CO (J=1-0), 13CO (J=1-0), and 12CO (J=2-1) emission data toward Gum 31. Three molecular clouds separated in velocity were detected at -2…
ALMA CO Observations of Gamma-Ray Supernova Remnant N132D in the Large Magellanic Cloud: Possible Evidence for Shocked Molecular Clouds Illuminated by Cosmic-Ray Protons
H. Sano, P. P. Plucinsky, A. Bamba +23
N132D is the brightest gamma-ray supernova remnant (SNR) in the Large Magellanic Cloud (LMC). We carried out CO( = 1-0, 3-2) observations toward the SNR using the Atacama…
Massive star formation in the Carina nebula complex and Gum 31 -- I. The Carina nebula complex
Shinji Fujita, Hidetoshi Sano, Rei Enokiya +10
Herein, we present results from observations of the 12CO (J=1-0), 13CO (J=1-0), and 12CO (J=2-1) emission lines toward the Carina nebula complex (CNC) obtained with the Mopra and N…
ALMA CO Observations of a Giant Molecular Cloud in M33: Evidence for High-Mass Star Formation Triggered by Cloud-Cloud Collisions
Hidetoshi Sano, Kisetsu Tsuge, Kazuki Tokuda +14
We report the first evidence for high-mass star formation triggered by collisions of molecular clouds in M33. Using the Atacama Large Millimeter/submillimeter Array, we spatially r…
Discovery of Shocked Molecular Clouds Associated with the Shell-Type Supernova Remnant RX J0046.57308 in the Small Magellanic Cloud
H. Sano, H. Matsumura, Y. Yamane +25
RX J0046.57308 is a shell-type supernova remnant (SNR) in the Small Magellanic Cloud (SMC). We carried out new CO( = 1-0, 3-2) observations toward the SNR using Mopra…
ALMA CO Observations of Supernova Remnant N63A in the Large Magellanic Cloud: Discovery of Dense Molecular Clouds Embedded within Shock-Ionized and Photoionized Nebulae
H. Sano, H. Matsumura, T. Nagaya +19
We carried out new CO( = 1-0, 3-2) observations of a N63A supernova remnant (SNR) from the LMC using ALMA and ASTE. We find three giant molecular clouds toward the northe…
Molecular Clouds associated with the Type Ia SNR N103B in the Large Magellanic Cloud
H. Sano, Y. Yamane, K. Tokuda +18
N103B is a Type Ia supernova remnant (SNR) in the Large Magellanic Cloud (LMC). We carried out new CO( = 3-2) and CO( = 1-0) observations using ASTE and ALMA. W…
Discovery of molecular and atomic clouds associated with the gamma-ray supernova remnant Kesteven 79
M. Kuriki, H. Sano, N. Kuno +21
We carried out CO( = 1-0) observations of the Galactic gamma-ray supernova remnant (SNR) Kesteven 79 using the Nobeyama Radio Observatory 45 m radio telescope, which has…
Discovery of Molecular and Atomic Clouds Associated with the Magellanic Superbubble 30 Doradus C
H. Sano, Y. Yamane, F. Voisin +15
We analyzed the 2.6-mm CO and 21-cm HI lines toward the Magellanic superbubble 30 Doradus C, in order to reveal the associated molecular and atomic gas. We uncovered five molecular…
