Evolution of the early-type fraction in massive galaxies at : how did early-type morphology form?
Masaru Kajisawa
Using /NIRCam data over a 0.28 deg area from COSMOS-Web survey, together with /ACS data, we investigate early-type fraction of massive galaxies with $M_{star}>10^{…

Relation between colour gradient and central asymmetric features for post-starburst galaxies at
Junya Fujimoto, Masaru Kajisawa
We investigated colour gradients of photometrically selected post-starburst galaxies (PSBs) at in the COSMOS field as a function of central concentration of asymmet…

A Wide and Deep Exploration of Radio Galaxies with Subaru HSC (WERGS). X. The Massive and Passive Nature of Radio Galaxies at
Yuta Yamamoto, Tohru Nagao, Takuji Yamashita +8
High- radio galaxies (HzRGs) are considered important objects for understanding the formation and evolution of massive galaxies in the early universe. However, till date, detail…
