Eventful Evolution of Giant Molecular Clouds in Dynamically Evolving Spiral Arms
Junichi Baba, Kana Morokuma-Matsui, Takayuki R. Saitoh
The formation and evolution of giant molecular clouds (GMCs) in spiral galaxies have been investigated in the traditional framework of the combined quasi-stationary density wave an…
CO Multi-line Imaging of Nearby Galaxies (COMING): I. Physical properties of molecular gas in the barred spiral galaxy NGC 2903
Kazuyuki Muraoka, Kazuo Sorai, Nario Kuno +16
We present simultaneous mappings of J=1-0 emission of 12CO, 13CO, and C18O molecules toward the whole disk (8' x 5' or 20.8 kpc x 13.0 kpc) of the nearby barred spiral galaxy NGC 2…
Gas velocity patterns in simulated galaxies: Observational diagnostics of spiral structure theories
Junichi Baba, Kana Morokuma-Matsui, Yusuke Miyamoto +2
There are two theories of stellar spiral arms in isolated disc galaxies that model stellar spiral arms with different longevities: quasi-stationary density wave theory, which chara…
An Effective Selection Method for Low-Mass Active Black Holes and First Spectroscopic Identification
Tomoki Morokuma, Nozomu Tominaga, Masaomi Tanaka +13
We present a new method to effectively select objects which may be low-mass active black holes (BHs) at galaxy centers using high-cadence optical imaging data, and our first spectr…
Formation, Evolution, and Revolution of Galaxies by SKA: Activities of SKA-Japan Galaxy Evolution Sub-SWG
Tsutomu T. Takeuchi, Kana Morokuma-Matsui, Daisuke Iono +4
Formation and evolution of galaxies have been a central driving force in the studies of galaxies and cosmology. Recent studies provided a global picture of cosmic star formation hi…
