FAUST III. Misaligned rotations of the envelope, outflow, and disks in the multiple protostellar system of VLA 16232417
Satoshi Ohashi, Claudio Codella, Nami Sakai +69
We report a study of the low-mass Class-0 multiple system VLA 1623AB in the Ophiuchus star-forming region, using HCO (), CS (), and CCH () lines as…
Rapid growth of seed black holes during early bulge formation
Kohei Inayoshi, Riouhei Nakatani, Daisuke Toyouchi +3
We study the early growth of massive seed black holes (BHs) via accretion in protogalactic nuclei where the stellar bulge component is assembled, performing axisymmetric two-dimens…
Photoevaporation of Minihalos during Cosmic Reionization: Primordial and Metal-Enriched Halos
Riouhei Nakatani, Anastasia Fialkov, Naoki Yoshida
The density distribution of the inter-galactic medium is an uncertain but highly important issue in the study of cosmic reionization. It is expected that there are abundant gas clo…
Super-Eddington accretion of dusty gas onto seed black holes: metallicity-dependent efficiency of mass growth
Daisuke Toyouchi, Takashi Hosokawa, Kazuyuki Sugimura +2
The super-Eddington accretion onto intermediate seed BHs is a potential formation mode of supermassive black holes exceeding in the early universe. We here investiga…
Photoevaporation of Molecular Gas Clumps Illuminated by External Massive Stars: Clump Lifetimes and Metallicity Dependence
Riouhei Nakatani, Naoki Yoshida
We perform a suite of 3D radiation hydrodynamics simulations of photoevaporation of molecular gas clumps illuminated by external massive stars. We study the fate of solar-mass clum…
