Spatially and Dynamically Extended Molecular Gas in Stephan's Quintet Revealed by ALMA CO(1-0) Total Power Mapping
Fumiya Maeda, Shinya Komugi, Kazuyuki Muraoka +15
We present ALMA Total Power CO(1-0) mapping of Stephan's Quintet (SQ), a prototypical compact galaxy group, with a uniform noise level at a spatial scale of ~25 kpc. These observat…
Measuring 60-pc-scale Star Formation Rate of the Nearby Seyfert Galaxy NGC 1068 with ALMA, HST, VLT/MUSE, and VLA
Yuzuki Nagashima, Toshiki Saito, Soh Ikarashi +7
Star formation rate (SFR) is a fundamental parameter for describing galaxies and inferring their evolutionary course. HII regions yield the best measure of instantaneous SFR in gal…
Volume density structure of the NGC253 CMZ through ALCHEMI excitation analysis
Kunihiko Tanaka, Jeffrey G. Mangum, Serena Viti +21
We present a spatially-resolved excitation analysis for the central molecular zone (CMZ) of the starburst galaxy NGC 253 using the data from the ALMA Large program ALCHEMI, whereby…
Distributions of the Density and Kinetic Temperature of the Molecular Gas in the Central Region of NGC 613 using Hierarchical Bayesian Inference
Hiroyuki Kaneko, Tomoka Tosaki, Kunihiko Tanaka +1
We present position-position-velocity (PPV) cubes of the physical and chemical properties of the molecular medium in the central 1.2 kpc region of the active galaxy NGC 613 at a PP…
ACA CO() Mapping of the Nearest Spiral Galaxy M33. I. Initial Results and Identification of Molecular Clouds
Kazuyuki Muraoka, Ayu Konishi, Kazuki Tokuda +18
We present the results of ALMA-ACA 7 m-array observations in CO(), CO(), and CO() line emission toward the molecular-gas disk in the Local…
Molecular Abundance of the Circumnuclear Region Surrounding an Active Galactic Nucleus in NGC 1068 based on Imaging Line Survey in the 3-mm Band with ALMA
Taku Nakajima, Shuro Takano, Tomoka Tosaki +9
We present an imaging molecular line survey in the 3-mm band (85-114 GHz) focused on one of the nearest galaxies with an active galactic nucleus (AGN), NGC 1068, based on observati…
