Analysis of 3 million HSC galaxies finds that galaxy bulge-to-total ratio depends on environment at fixed stellar mass, with the strength and scale of this dependence varying by redshift and galaxy mass.
The SFR-M_* relation develops a high-mass decline at low redshifts, driven mainly by morphological quenching from internal structure rather than environmental effects on star-forming galaxies.
