ISHIBASHI Akihiro

Position
Professor
Laboratory
General Relativity and Cosmology Laboratory
General Relativity, Gravitation, Cosmology

Investigation is conducted into overall space dynamics and black holes using general relativity. A focus of research is on high-dimensional space models and high-dimensional black holes, which look at the possibilities of high-dimensional space-time.

INOUE TARO Kaiki

Position
Professor
Laboratory
Laboratory for Cosmology
Cosmology, Astrophysics, Gravitational Astronomy

Dark matter and dark energy are mysterious substances that account for a large portion of the universe. Solutions to these mysterious substances are sought using general relativistic phenomena on cosmic scales such as gravitational lenses, gravitational waves and cosmic inhomogeneity (halos and voids).

NOBUKAWA Kumiko

High-energy Astrophysics Lab.
High-energy Astrophysics

X-ray observations have revealed that the universe is hot and energetic. My research focuses on high-energy phenomena occurring in our galaxy. I am also developing the CCD detector onboard the XRISM satellite.

ANTON Timur Jaelani

Position
Researcher
Laboratory
Laboratory for Cosmology
Observational cosmology, Astrophysics, Gravitational lensing

Strong gravitational lenses are valuable phenomena for studying astrophysics and cosmology. Lensing is a unique probe of the (dark) matter distribution at large-scale and also can act as a natural telescope that magnifies the background sources, allowing for detailed studies of their properties at high resolution. This phenomena appear as a unique probe of the dark matter structure of galaxies, groups, and clusters, as well as an independent tool for constraining cosmological parameters.

Laboratory for Cosmology
Cosmology, Astrophysics

The universe is mainly composed of unknown "dark matter" and "dark energy". Their nature have not been understood. Investigating the nature is important to understand the universe and test the Einstein's theory of general relativity. We will investigate the nature by carrying out gravitational lensing analysis of simulations and multi-wavelength data.
