Molecular abundances in nearby galaxies (NGC 1068, NGC 253, and IC 342)

Image

Shuro Takano

Nihon University

The results from Nobeyama 45 m radio telescope observations of nearby galaxies NGC 1068, NGC 253, and IC 342 on the composition of the molecular gas will presented. NGC 1068 contains an active galactic nucleus (AGN), and the 45 m observations provide good spatial resolution to investigate the composition of...

Growth by Super-Eddington Accretion of Seed Black Holes in Primordial Galaxies

Image

Daisuke Toyouchi

University of Kyoto, Theoretical Astrophysics Group

Recent observations have revealed that giant black holes with masses of several hundred million times larger than the Sun already exist in the early universe at redshift z ~ 7. One of the leading theories for the formation of supermassive black holes in such an early universe is supercritical accretion...

The current status of galaxy formation at redshift 3

Image

Hideki Umehata

Riken

In the standard paradigm of coslmological large scale structure formation in Λ cold dark matter universe, dark matter and baryons gravitationally collapse into a spider web-like network called the cosmic web. In the current theoretical picture, gas inflow and accretion and galaxy formation progresses at the nodes of the cosmic...

Formation of multiple Pop III stars under radiation feedback

Image

Kazuyuki Sugimura

University of Maryland

Population III (Pop III) stars, forming as the first generation objects in the history of the Universe, bring an end to the dark age of the Universe and pollute the pristine intergalactic medium with heavy elements. Based on recent theoretical studies, there is general agreement that the typical mass scale...

A series of "most distant" results

Image

Akio Inoue

Waseda University

Recently, using Subaru and ALMA, we were able to make a series of press releases entitled “most distant XYZ”. That is, the most distant oxygen (2016.6), the most distant bright emission line (2018.5), the most distant galaxy merger (2019.6), the most distant passive galaxy (2019.9), and the most distant primitive...

New insights into the formation of massive galaxies and galaxy clusters in the early universe

Image

Tao Wang

University of Tsukuba, Center for Computatational Sciences

During the last decades, our understanding on both galaxy and structure formation in the nearby Universe has been great advanced, thanks to various large cosmological surveys. On the other hand, limited by the capabilities of current facilities, the early stages of both galaxy and structure formation are still not well...

Gravitational instability and fragmentation of spiral arms

Image

Shigeki Inoue

University of Tsukuba, Center for Computatational Sciences

Spiral arms in a disc are structures found in various astronomical objects. Sometimes spiral arms fragment into smaller structures. In this study, the condition for gravitational instability of spiral arms was analytically derived by a linear perturbation analysis. Comparison with simulations confirmed that the analytical solutions can accurately predict the...

Massive star formation through molecular cloud collisions and triggered star-formation through feedback

Image

Kazuhiro Shima

Kyoto University, Theoretical Astrophysics Group

In recent years, molecular cloud collisions have attracted attention as the formation process of massive stars and massive clusters. Takahira et al (2014) conducted three-dimensional fluid simulations in which two molecular clouds collide, and reported that a high density turbulent core exceeding 100 solar masses is formed. However, the models...
