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…
Multiphase Gas Structure in the Circumnuclear Region of NGC 5506 Observed with ALMA
Kana Takechi, Hiroshi Nagai, Nozomu Kawakatu +7
We present a study of the multiphase gas structure and kinematics of the circumnuclear disk (CND) of NGC 5506, a nearby edge-on Seyfert galaxy, at a spatial resolution of …
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…
ALMA 0.02"-resolution observations reveal HCN-abundance-enhanced counter-rotating and outflowing dense molecular gas at the NGC 1068 nucleus
Masatoshi Imanishi, Dieu D. Nguyen, Keiichi Wada +6
We present ALMA ~0.02"-resolution observations of the nucleus of the nearby (~14 Mpc) type-2 AGN NGC 1068 at HCN/HCO+/HNC J=3-2 lines, as well as at their 13C isotopologue and vibr…
ALMA Reveals an Inhomogeneous Compact Rotating Dense Molecular Torus at the NGC 1068 Nucleus
Masatoshi Imanishi, Kouichiro Nakanishi, Takuma Izumi +1
We present the results of our ALMA Cycle 4 high-spatial-resolution (0.04-0.07") observations, at HCN J=3-2 and HCO+ J=3-2 lines, of the nucleus of NGC 1068, the nearby prototypical…
