SANHUEZA Patricio, Associate Professor
Space, Particle Physics & Aerospace1 student voices
The Sanhueza Lab studies how massive stars, which are far heavier than the Sun, are born. Massive stars end their lives in supernova explosions that scatter heavy elements throughout the universe. Using radio interferometers such as ALMA and the VLA as its main tools, the lab observes clumps of gas at the stage before stars form. In an international team, the lab investigates everything from the role of magnetic fields and how binary stars form to the mechanisms that determine stellar mass.

Shigeyuki Sako, Associate Professor
Space, Particle Physics & Aerospace1 student voices
Sako Lab studies optical and infrared time-domain astronomy, tracking celestial objects whose appearance changes over short timescales. Phenomena that change on timescales of seconds have so far been poorly explored, and the targets include meteors, small bodies, and sudden explosive events. The lab continuously images the sky with instruments such as Tomo-e Gozen, a wide-field video camera mounted on the Kiso Schmidt Telescope. A distinguishing feature of the group is that it develops the observation instruments and detectors themselves.

Tomonori Totani, Professor
Space, Particle Physics & Aerospace1 student voices
The Totani Lab studies the origin of the universe and the astronomical phenomena that take place within it from a theoretical perspective. Its subjects are broad: cosmology, the formation and evolution of galaxies, and explosive objects such as supernovae and gamma-ray bursts. Rather than pursuing pure theory, the lab interprets the puzzles posed by the latest observational data through theory and models. The lab works on the belief that science advances only when theory and observation mesh like the two wheels of a cart.

Nobunari Kashikawa, Professor
Space, Particle Physics & Aerospace1 student voices
The Kashikawa Lab mainly uses the Subaru Telescope to conduct observational studies of distant objects and the early universe. Key topics include distant galaxies, first-generation galaxies, first-generation black holes, and protoclusters. The lab traces the period from the dark ages, when the universe was filled with neutral hydrogen, to the era when the first objects began ionizing the surrounding space. The lab also investigates young structures before they grow into galaxy clusters, as well as the relationship between invisible dark matter and ordinary matter.

Mareki Honma, Professor
1 student voices
The Honma Lab studies radio astronomy and galactic astronomy. Using ultra-high-resolution interferometric observations that combine many radio telescopes, the lab works on directly imaging black holes. The lab also investigates the structure of the Milky Way and dark matter through astrometric observations, which precisely measure the positions of stars. Prof. Honma belongs to the Mizusawa VLBI Observatory of the National Astronomical Observatory of Japan and serves as the observatory's director.

Takuma Izumi, Associate Professor
1 student voices
The Izumi Lab studies active galactic nuclei, the brightly shining centers of galaxies. Using radio waves, mainly millimeter and submillimeter waves, the lab observes active galactic nuclei across the universe, both nearby and in the distant past. The lab investigates how supermassive black holes grow and how active galactic nuclei affect the growth and evolution of galaxies. Associate Professor Izumi belongs to the ALMA Project at the National Astronomical Observatory of Japan.

Kazunori Kori, Professor
1 student voices
The Kori Lab theoretically studies the beginning of the universe and the mysteries that arise in compact objects such as black holes. To do so, the lab uses quantum field theory, general relativity, cosmology, and mathematics. The universe was born 13.8 billion years ago and expanded from a fireball state known as the Big Bang into the vast universe we see today. The lab keeps asking what happened before that fireball formed, and what dark matter and dark energy really are.

Fumi Egusa, Associate Professor
Space, Particle Physics & Aerospace0 student voices
The Egusa Lab studies how gas moves and how stars form in spiral and barred spiral galaxies. The lab belongs to the Radio Astronomy Group at the Institute of Astronomy, and its observations center on ALMA, which operates in the Atacama highlands of Chile. Using the spectral lines of molecules and atoms visible at radio, millimeter, and submillimeter wavelengths, the lab investigates the interstellar medium of galaxies. The lab is also pursuing statistical studies that compile large numbers of molecular clouds in nearby galaxies and in the Milky Way.

Itsuki Sakon, Associate Professor
Space, Particle Physics & Aerospace0 student voices
The Sakon Lab studies what cosmic environments were needed before humans could emerge on Earth, and how common such conditions are. Heavy elements such as carbon and nitrogen, produced over the course of a star's life, are scattered into their surroundings when the star dies, chemically enriching the universe. The lab's main methods are infrared observation from the ground and from satellites, and laboratory astrophysics, in which cosmic dust is made in the laboratory. The lab does not limit itself to particular methods; it tries to move one step at a time toward an answer to this question from every possible angle.

KWON Jungmi, Associate Professor
Space, Particle Physics & Aerospace0 student voices
The Kwon Lab studies how stars, planetary systems, and exoplanets form and evolve. The lab carries out polarimetric observations at multiple wavelengths, which can map the structures around stars and the shapes of magnetic fields. By systematically conducting circular and linear polarization surveys, the lab also investigates the origin of the homochirality of life. The lab also develops polarimetric instruments to be mounted on ground-based and space telescopes, and works on astrobiology experiments.
