CO Multi-line Imaging of Nearby Galaxies (COMING). IX. $^{12}$ CO( $J$ =2-1)/ $^{12}$ CO( $J$ =1-0) line ratio on kiloparsec scales

Yoshiyuki Yajima, Kazuo Sorai, Yusuke Miyamoto +8

While molecular gas mass is usually derived from $^{12}$ CO( $J$ =1-0) - the most fundamental line to explore molecular gas - it is often derived from $^{12}$ CO( $J$ =2-1) assuming a co…

Observations of the [CI] ( $^{3} P_{1}$ - $^{3} P_{0}$ ) emission toward the massive star-forming region RCW38: further evidence for highly-clumped density distribution of the molecular gas

Natsuko Izumi, Yasuo Fukui, Kengo Tachihara +14

We present observations of the $^{3} P_{1}$ - $^{3} P_{0}$ fine-structure line of atomic carbon using the ASTE 10 m sub-mm telescope towards RCW38, the youngest super star cluster in the Milky…

Coded equivalence of one-sided topological Markov shifts

Kengo Matsumoto

We introduce a notion of coded equivalence in one-sided topological Markov shifts. The notion is inspired by coding theory. One-sided topological conjugacy implies coded equivalenc…

The Molecular Mass function of the Local Universe

P. Andreani, Y. Miyamoto, H. Kaneko +4

We construct the molecular mass function using the bivariate Kband-Mass Function of the Herschel Reference Survey, a volume-limited sample already widely studied at the entire elec…

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 $^{12}$ CO( $J = 1 - 0$ ) (hereafter $^{12}$ CO)…

Spin Parity of Spiral Galaxies II: A catalogue of 80k spiral galaxies using big data from the Subaru Hyper Suprime-Cam Survey and deep learning

Ken-ichi Tadaki, Masanori Iye, Hideya Fukumoto +4

We report an automated morphological classification of galaxies into S-wise spirals, Z-wise spirals, and non-spirals using big image data taken from Subaru/Hyper Suprime-Cam (HSC)…
