Research interests: Galaxy formation and evolution, Cosmological hydrodynamic simulations, Dwarf galaxies, Internal dynamics and kinematics of galaxies, Baryon cycle
Hi! I am Kazuki Tomaru (Japanese: 戸丸 一樹), a Ph.D. student in the Theoretical Astrophysics (OUTAP) Group, Department of Earth and Space Science, Graduate School of Science, The University of Osaka, Japan, under the supervision of Prof. Kentaro Nagamine.
My research centers on galaxy formation and evolution in a cosmological context with the aim of constructing a unified picture of galaxies we observe in diverse forms and properties and uncovering the underlying fundamental physical processes. To consistently capture the complex interplay of phenomena across multiple length-scales and timescales, from large-scale structure formation to star formation activities within individual galaxies, I employ cosmological zoom-in hydrodynamic simulations.
I currently conduct simulations of dwarf galaxies and am interested in the evolution of their shapes.

I perform and analyze cosmological zoom-in hydrodynamic simulations of dwarf galaxies using the GADGET4-OSAKA code. We study their morphological and kinematic diversity of gas and stars within these systems, providing crucial insights into the galaxy–halo connection at the low-mass end of galaxy formation.
