The flickering nuclear activity of Fornax A
F. M. Maccagni, M. Murgia, P. Serra +13
We present new observations of Fornax A taken at 1 GHz with the MeerKAT telescope and at 6 GHz with the Sardinia Radio Telescope (SRT). The sensitive (noise ~16 micro-Jy beam$^{-1}…
CO Multi-line Imaging of Nearby Galaxies (COMING) IV. Overview of the Project
Kazuo Sorai, Nario Kuno, Kazuyuki Muraoka +36
Observations of the molecular gas in galaxies are vital to understanding the evolution and star-forming histories of galaxies. However, galaxies with molecular gas maps of their wh…
ALMA observations of molecular gas in the host galaxy of AT2018cow
Kana Morokuma-Matsui, Tomoki Morokuma, Nozomu Tominaga +7
We investigate the molecular gas in, and star-formation properties of, the host galaxy (CGCG 137-068) of a mysterious transient, AT2018cow, at kpc and larger scales, using archival…
Star Formation Efficiencies at Giant Molecular Cloud Scales in the Molecular Disk of the Elliptical Galaxy NGC 5128 (Centaurus A)
D. Espada, S. Verley, R. E. Miura +15
We present ALMA CO(1-0) observations toward the dust lane of the nearest elliptical and radio galaxy, NGC 5128 (Centaurus A), with high angular resolution ( 1 arcsec, or 18 p…
Complex distribution and velocity field of molecular gas in NGC 1316 as revealed by Morita Array of ALMA
Kana Morokuma-Matsui, Paolo Serra, Filippo M. Maccagni +11
We present the results of CO(=1-0) mosaicing observations of the cD galaxy NGC 1316 at kpc-resolution performed with the Morita Array of the Atacama Large Millimeter/subm…
Do Galaxy Morphologies Really Affect the Efficiency of Star Formation during the Phase of Galaxy Transition?
Shuhei Koyama, Yusei Koyama, Takuji Yamashita +11
Recent simulations predict that the presence of stellar bulge suppress the efficiency of star formation in early-type galaxies, and this `morphological quenching' scenario is suppo…
CO Multi-line Imaging of Nearby Galaxies (COMING). III. Dynamical effect on molecular gas density and star formation in the barred spiral galaxy NGC 4303
Yoshiyuki Yajima, Kazuo Sorai, Nario Kuno +24
We present the results of CO(=1-0) and CO(=1-0) simultaneous mappings toward the nearby barred spiral galaxy NGC 4303 as a part of the CO Multi-line Imaging of…
CO Multi-line Imaging of Nearby Galaxies (COMING): VI. Radial variations in star formation efficiency
Kazuyuki Muraoka, Kazuo Sorai, Yusuke Miyamoto +25
We examined radial variations in molecular-gas based star formation efficiency (SFE), which is defined as star formation rate per unit molecular gas mass, for 80 galaxies selected…
CO Multi-line Imaging of Nearby Galaxies (COMING). VII. Fourier decomposition of molecular gas velocity fields and bar pattern speed
Dragan Salak, Yuto Noma, Kazuo Sorai +24
The CO velocity fields of a sample of 20 nearby spiral galaxies, selected from the CO Multi-line Imaging of Nearby Galaxies (COMING) legacy project of No…
