Newborn spheroids at high redshift : When and how did the dominant, old stars in today's massive galaxies form?
(2013-01-11)
We study ~330 massive (M > 10M), newborn spheroidal galaxies (SGs) around the epoch of peak star formation (1 <z <3) to explore the high-redshift origin of SGs and gain insight into when and how the old stellar populations ...
Minor-merger-driven growth of early-type galaxies over the last 8 billion years
(Cambridge University Press, 2011-09)
We summarise recent progress in understanding the star formation activity in early-type galaxies (ETGs), using recent studies that leverage photometry in the rest-frame ultraviolet (UV) wavelengths. While classically thought ...
