Extracting information from emission line intensity maps using deep learning

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...

Exploring Molecular Clouds in our Galaxy with FUGIN

Saito Hiro

University of Tsukuba

Molecular gas is a major component of the interstellar medium of the Milky Way Galaxy. Molecular cloud are the main environment in which stars form, so elucidating their spatial distribution and formation mechanism in the Galaxy is an important research field. Recent advances in interferometer observations have identified numerous macromolecular...

Supermassive star formation via super competitive accretion in slightly metal-enriched clouds

Sunmyon Chon

Theoretical Astrophysics Group, University of Tohoku

Recent distant quasar surveys covering z > 6 have revealed a number of supermassive black holes (SMBH). One of the models for the formation of these SMBHs is the formation of supermassive stars (SMSs) in the early universe, leaving behind a seed BH after a "direct collaps". In gas clouds,...

New observational methods using hyperfine structure lines of the heavy elements of the Warm-Hot Intergalactic Medium

Kohji Yoshikawa

University of Tsukuba

The observationally identifiable total mass of baryons in the present day universe is known to be significantly smaller than the mass derived from the cosmic microwave background radiation and neutral hydrogen absorption line studies of the distant universe. The unobserved baryons in the current universe are sometimes called dark baryons...

The growth of distant galaxies as seen by ALMA

Takuya Hashimoto

University of Tsukuba

Observations of distant galaxies are important for (i) elucidating the evolution of galaxy formation, and (ii) understanding the contribution of galaxies to the reionization of the universe. In recent years, a number of candidate distant galaxies have been discovered by large ground-based telescopes and space telescopes, some of which have...
