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…
