The insignificance of major mergers in driving star formation at z ≃ 2
We study the significance of major-merger-driven star formation in the early Universe, by quantifying the contribution of this process to the total star formation budget in 80 massive (M* > 1010 M) galaxies at z ≃ 2. ...
Newborn spheroids at high redshift : When and how did the dominant, old stars in today's massive galaxies form?
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 ...
