Hyper Suprime-Cam Subaru Strategic Program: A Mass-Dependent Slope of the Galaxy Size-Mass Relation at $z<1$

Abstract

We present the galaxy size-mass ($R_e-M_{\ast }$) distributions using a stellar-mass complete sample of $\sim 1.5$ million galaxies, covering $\sim 100$ deg${}^2$, with $\log (M_{\ast }/M_{\odot })>10.2(9.2)$ over the redshift range $0.2<z<1.0$ $(z<0.6)$ from the second public data release of the Hyper Suprime-Cam Subaru Strategic Program. We confirm that, at fixed redshift and stellar mass over the range of $\log (M_{\ast }/M_{\odot })<11$, star-forming galaxies are on average larger than quiescent galaxies. The large sample of galaxies with accurate size measurements, thanks to the excellent imaging quality, also enables us to demonstrate that the $R_e-M_{\ast }$ relations of both populations have a form of broken power-law, with a clear change of slopes at a pivot stellar mass $M_p$. For quiescent galaxies, below an (evolving) pivot mass of $\log (M_p/M_{\odot })=10.2-10.6$ the relation follows $R_e\propto M_{\ast }^{0.1}$; above $M_p$ the relation is steeper and follows $R_e\propto M_{\ast }^{0.6-0.7}$. For star-forming galaxies, below $\log (M_p/M_{\odot })\sim 10.7$ the relation follows $R_e\propto M_{\ast }^{0.2}$; above $M_p$ the relation evolves with redshift and follows $R_e\propto M_{\ast }^{0.3-0.6}$. The shallow power-law slope for quiescent galaxies below $M_p$ indicates that large low-mass quiescent galaxies have sizes similar to those of their counterpart star-forming galaxies. We take this as evidence that large low-mass quiescent galaxies have been recently quenched (presumably through environment-specific process) without significant structural transformation. Interestingly, the pivot stellar mass of the $R_e-M_{\ast }$ relations coincides with mass at which half of the galaxy population is quiescent, implied that the pivot mass represents the transition of galaxy growth from being dominated by in-situ star formation to being dominated by (dry) mergers.
