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 outflow in the reionization-epoch quasar J2054-0005 revealed by OH 119 m observations
Dragan Salak, Takuya Hashimoto, Akio K. Inoue +8
Molecular outflows are expected to play a key role in galaxy evolution at high redshift. To study the impact of outflows on star formation at the epoch of reionization, we performe…
CO Multi-line Imaging of Nearby Galaxies (COMING). XII. CO-to-H Conversion Factor and Dust-to-Gas Ratio
Atsushi Yasuda, Nario Kuno, Kazuo Sorai +8
We simultaneously measured the spatially-resolved CO-to-H conversion factor () and dust-to-gas ratio (DGR) in nearby galaxies on a kiloparsec scale. In this st…
Investigating physical states of molecular gas in the overlapping region of interacting galaxies NGC4567/4568 using ALMA
Hiroyuki Kaneko, Shoya Tokita, Nario Kuno
We present ALMA observations of a diffuse gas tracer, CO(J = 1-0), and a warmer and denser gas tracer, CO(J = 3-2), in the overlapping region of interacting galaxies NGC 4567/4568,…
Diverse Molecular Structures Across The Whole Star-Forming Disk of M83: High fidelity Imaging at 40pc Resolution
Jin Koda, Akihiko Hirota, Fumi Egusa +23
We present high-fidelity CO(1-0) imaging of molecular gas across the full star-forming disk of M83, using ALMA's 12m, 7m, and TP arrays and the MIRIAD package. The data have a mass…
Detections of [C II] 158 m and [O III] 88 m in a Local Lyman Continuum Emitter, Mrk 54, and its Implications to High-redshift ALMA Studies
Ryota Ura, Takuya Hashimoto, Akio K. Inoue +17
We present integral field, far-infrared (FIR) spectroscopy of Mrk 54, a local Lyman Continuum Emitter (LCE), obtained with FIFI-LS on the Stratospheric Observatory for Infrared Ast…
