The Milky Way's central supermassive black hole observed by the Event Horizon Telescope: results and future prospects

Kotaro Moriyama

Goethe University Frankfurt

On May 12, 2022, the Event Horizon Telescope (EHT) Collaboration released the world's first images of the close vicinity (several gravitational radii scale) of Sgr A*, the supermassive black hole at the center of our Milky Way Galaxy. The EHT is an international collaborative research project that links telescopes from...

ALMA/NOEMA view of galaxy-scale molecular outflows

Dragan Salak

Hokkaido University

Kiloparsec-scale outflows of gas and dust are thought to be an important mechanism in regulating star formation in galaxies and increasing the metallicity of circumgalactic and intergalactic media. In the past two decades, outflows have been discovered in numerous galaxies with vigorous star formation (starburst) and active galactic nuclei (AGN)...

UV & Ly-alpha halos of LAEs across environments at z=2.84

Satoshi Kikuta

University of Tsukuba, Center for Computational Sciences

Diffuse Lyα emission around galaxies, or Lyα halo (LAH), is a valuable probe of their circumgalactic medium which regulate galaxy evolution. We present UV & Lyα radial surface brightness (SB) profiles of Lyα emitters (LAEs) at z = 2.84 detected with the HSC on the Subaru Telescope. UV and Lyα...

A multifaceted study of the remnants of first stars

Takanobu Kirihara

University of Tsukuba, Center for Computational Sciences

The first stars play a particularly important role in the history of the universe because they are the first luminous objects in our universe and the first to produce heavy elements. However, no direct observational traces of them have yet been obtained. Now, the operation of a new generation of...
