Kotaro Kohno, Professor
Space, Particle Physics & Aerospace0 student voices
The Kohno Lab uses millimeter and submillimeter observations to study how galaxies, the groups they form, and the massive black holes within them were born and have evolved. The lab belongs to the Radio Astronomy Group at the Institute of Astronomy. Centered on ALMA, it also combines data from optical, infrared, and X-ray telescopes in its investigations. The lab is also developing line intensity mapping, a new observational technique, along with the instruments and data analysis methods it requires. Whether a student's focus is observation or instrument development, the lab's basic policy is for each person to pursue the research they want to do as thoroughly as possible. Associate Professor Fumi Egusa, who belongs to the same group, studies how gas moves and how stars form within spiral and barred spiral galaxies.

Takashi Miyata, Professor
Space, Particle Physics & Aerospace0 student voices
The Miyata Lab studies methods for observing the universe in mid-infrared light. Mid-infrared light is emitted by relatively cool matter, which makes it well suited for observing the surroundings of newborn stars and the dust released by dying stars. The lab handles everything itself, from developing observing instruments to carrying out observations, and is building instruments to be mounted on the telescope at the University of Tokyo Atacama Observatory (TAO) in Chile. Ground-based telescope projects run for a shorter period than space telescope projects, so undergraduate and graduate students can take the lead in the research.

Kentaro Motohara, Professor
Space, Particle Physics & Aerospace0 student voices
The Motohara Lab develops instruments for observing the universe in the near-infrared, and uses them to observe galaxies. Astronomy has made one discovery after another by building instruments that can observe at wavelengths and levels of detail not previously possible. The lab builds instruments that observe near-infrared light at wavelengths of 1–2.5 μm, aiming to unravel the mysteries of galaxy formation and evolution, from nearby galaxies to distant ones. The work spans a wide range, from developing instrument hardware and software to observations, data analysis, and scientific discussion.

Takeo Minezaki, Project Professor
Space, Particle Physics & Aerospace0 student voices
The lab studies the co-evolution of black holes and galaxies, as well as cosmology, using the methods of time-domain astronomy and focusing mainly on active galactic nuclei. An active galactic nucleus is an object in which gas falls onto the supermassive black hole at the center of a galaxy and emits intense light from a very small region. Observations are mainly made in infrared and optical light, and X-ray and radio observational data are also used depending on research interests. The lab is also involved in developing observing instruments for astronomical research and in getting the TAO Telescope and the MAGNUM Telescope up and running.

Naoto Kobayashi, Associate Professor
Space, Particle Physics & Aerospace0 student voices
The Kobayashi-Niino Lab studies astronomical objects whose brightness changes over short timescales, using optical observations. It uses the Schmidt telescope at the University of Tokyo's Kiso Observatory and the Tomo-e Gozen camera, which captures a wide field of sky like a video. The lab searches for optical counterparts to gravitational waves and FRBs, and also follows flares and variability caused by mass accretion in newly formed young stars. Any object that can be observed with high-speed optical photometry is a possible target.

Yuri Aikawa, Professor
Space, Particle Physics & Aerospace0 student voices
Aikawa Lab studies how stars and planetary systems form, as well as astrochemistry, the chemistry of the universe. The lab looks not only at the physical processes by which stars and planets form, but also at how the interstellar material they are made from changes over time. The lab combines theoretical and observational approaches, and also makes use of detailed observations with the ALMA radio telescope. Assistant Professor Ohashi, who specializes in radio observations, is also part of the lab, so the lab covers both theory and observation.

Michiko Fujii, Professor
Space, Particle Physics & Aerospace0 student voices
The Fujii Lab uses simulations to study how galaxies, star clusters, and planetary systems form and how they have evolved. The lab's core method is N-body simulation, which follows systems of particles such as stars, dark matter, and planetesimals bound together by gravity by calculating the motion of each individual particle. The real appeal of simulation research is that it lets researchers "see" the evolution of the universe, which unfolds over timescales far longer than a human lifetime. The lab also develops the computational codes needed for large-scale simulations.

Kazuhiro Shimasaku, Associate Professor
Space, Particle Physics & Aerospace0 student voices
The Shimasaku Lab studies when and how galaxies were born and how they evolved into their present form. Most of the stars in the universe belong to some galaxy, and the Sun is also located within a spiral galaxy, the Milky Way. The lab mainly uses visible-light and near-infrared observational data to work on galaxy formation and evolution and related questions. On its website, the lab invites students who are considering a lab to a meeting, where it wants to explain its research themes and its approach to research.

Hideyuki Umeda, Associate Professor
Space, Particle Physics & Aerospace0 student voices
The Umeda Lab uses numerical simulations to study the evolution of stars and the origin of the elements. The lab calculates how massive stars explode in supernovae and gamma-ray bursts at the end of their lives, starting from the stars' evolution before the explosion. It also calculates the elements produced during the explosion and verifies the theory by comparing the results with the chemical composition of actual stars and galaxies. For those considering an undergraduate research project or graduate school, the lab's website says it will provide an explanation via Zoom or similar tools upon request.
