On the Tidal Formation of Dark Matter Deficient Galaxies

Image

Go Ogiya

University of Waterloo

Recently, observations reported that the ultra diffuse galaxy NGC1052-DF2 (DF2), believed to be a member of the NGC1052 group, is dark matter (DM) deficient. Its inferred DM mass is smaller, by a factor of a few hundred, than what is expected based on its stellar mass and empirical models for...

Structure of the magnetic field driving active galactic nuclear jets probed by polarized light images

Image

Yu Tsuneto

Kyoto University

With the success of the Event Horizon Telescope in directly imaging a supermassive black hole, the study of black holes has entered a new era in which the properties of black holes are explored through imaging observations. In particular, the polarized images reveal the magnetic field structure near the black...

Identifying galactic structures in a galaxy more than 12 billion years ago using the gas dynamics

Image

Takafumi Tsukui

Sokendai

Spiral galaxies observed today (redshift z=0) have distinct internal structures: supper massive black hole (SMBH), dense stellar cluster known as bulge; a flat rotating disk; and extended dark matter halo. The cosmic averaged star formation is suggested to peak at z~2. It remains unclear when and how these structures formed...

A theoretical framework for cosmological analysis of 21-cm line observations

Image

Rika Ando

Nagoya University

Observations confirm that the universe is accelerating and expanding. Dark energy and modified gravity theories have been proposed but a conclusive theory remains elusive. The difference between these theoretical models is reflected in the magnitude of density fluctuations and the temporal evolution of large-scale structure. Therefore, it is possible to...

The Diversity of IGM-galaxy connection among galaxies at redshift z = 2-3

Image

Rieko Momose

University of Tokyo

The link between the intergalactic medium (IGM) and galaxies is key to understand the evolution of baryonic matter and galaxies. In fact, several observational studies have confirmed the connection between the IGM HI and galaxies up to several tens comoving Mpc. However, understanding the variations on the IGM-galaxy connection over...

Hybernating black holes: galaxy collisions and black hole activity

Image

Masao Mori

University of Tsukuba, Center for Computational Sciences

Supermassive black holes in the universe that exceed one million times the mass of the sun are ubiquitous in the universe. A small proportion of supermassive black holes shine brightly and show intense activity, using accreted matter as an energy source, but most black holes hybernate quietly in the center...

Supermassive black hole seed formation in the early universe

Image

Yuya Sakurai

IPMU

Recent three-dimensional cosmological simulations of protogalaxy formation have suggested that supermassive stars (SMSs) can form in warm gas clouds in which H2–cooling is overwhelmed by dynamical heating (Wise et al. 2019), but they stopped short of following the growth of a central protostar. Here we we examine whether accretion on...

Extracting information from emission line intensity maps using deep learning

Image

Moriwaki Kana

University of Tokyo

Observations of large-scale structure in the universe can place constraints on the theories of cosmology, galaxy formation, and reionization. A relatively new observation method called emission-line intensity mapping can reveal the three-dimensional distribution of galaxies and intergalactic gas over a wide area by analyzing the spatial fluctuations in emission line...
