Vaulting the barrier: An intrinsic mechanism to fuel the gas beyond the nuclear ring into the central region of barred galaxies
Kotaro Kobayashi, Naomichi Yutani, Takayuki R. Saitoh +2
Gas delivery to galactic centers powers nuclear starbursts and active galactic nuclei (AGNs), yet bar-driven inflow is generally expected to stall in a nuclear ring a few hundred p…
Dense Ionized Outflow with Five Narrow Components in a Dust-obscured Galaxy
Taketo Yoshida, Tohru Nagao, Yoshiki Toba +4
We present our discovery of a complex ionized outflow in SDSS J101034.28+372514.7 (J1010+3725), a dust-obscured galaxy (DOG) at . The SDSS optical spectrum of J1010+3725 s…
Dynamical Mechanism of Episodic Gas Accretion to the Central Region of Spiral Galaxies
Naomichi Yutani, Nozomu Kawakatu, Takayuki Saitoh +1
We performed \textit{N}-body/SPH simulations of isolated spiral galaxies with various bulge-to-disk mass ratios () from 0.02 to 0.2 to investigate mass…
Dust-obscured Galaxies with Broken Power-law Spectral Energy Distributions Discovered by UNIONS
Taketo Yoshida, Tohru Nagao, Yoshiki Toba +11
We report on the spectral energy distributions (SEDs) of infrared-bright dust-obscured galaxies (DOGs) with . Using photometry from the deep and wide…
Apparent effect of dust extinction on the observed outflow velocity of ionized gas in galaxy mergers
Naomichi Yutani, Yoshiki Toba, Keiichi Wada
In this study, we examine photoionization outflows during the late stages of galaxy mergers, with a specific focus on the relation between observed velocity of outflowing gas and t…
Origin and evolution of dust-obscured galaxies in galaxy mergers
Naomichi Yutani, Yoshiki Toba, Shunsuke Baba +1
Dust Obscured Galaxies (DOGs), which are observationally characterized as faint in the optical and bright in the infrared, are the final stage of galaxy mergers and are essential o…
The eROSITA Final Equatorial-Depth Survey (eFEDS): A multiwavelength view of WISE mid-infrared galaxies/active galactic nuclei
Yoshiki Toba, Teng Liu, Tanya Urrutia +21
We investigate the physical properties--such as the stellar mass, SFR, IR luminosity, X-ray luminosity, and hydrogen column density--of MIR galaxies and AGN at in the 140 d…
Mass accretion toward black holes in the final phase of galaxy mergers
Takeru Kawaguchi, Naomichi Yutani, Keiichi Wada
We studied the final phases of galactic mergers, focusing on interactions between supermassive black holes (SMBHs) and the interstellar medium in a central sub-kpc region, using an…
