CO Multi-line Imaging of Nearby Galaxies (COMING). XI. Azimuthally averaged star formation rate and stellar mass relation with molecular gas amount

Ayumi Kajikawa, Kazuo Sorai, Kana Morokuma-Matsui +13

This study investigated the relation between the surface density of star formation rate (SFR) (), stellar mass (), and molecular gas mass ($Σ_{M_\ma…

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…

CO Multi-line Imaging of Nearby Galaxies (COMING). IX. CO(=2-1)/CO(=1-0) line ratio on kiloparsec scales

Yoshiyuki Yajima, Kazuo Sorai, Yusuke Miyamoto +8

While molecular gas mass is usually derived from CO(=1-0) - the most fundamental line to explore molecular gas - it is often derived from CO(=2-1) assuming a co…

CO Multi-line Imaging of Nearby Galaxies (COMING). X. Physical conditions of molecular gas and the local SFR-Mass relation

Kana Morokuma-Matsui, Kazuo Sorai, Yuya Sato +7

We investigate the molecular gas properties of galaxies across the main sequence of star-forming (SF) galaxies in the local Universe using CO() (hereafter CO)…

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…

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…
