We investigate the relationship between the quenching of star formation and the structural transformation of massive galaxies, using a large sample of photometrically-selected poststarburst galaxies in the UKIDSS UDS field. We find that post-starburst galaxies at highredshift (z > 1) show high Sersic indices, significantly higher than those of active star-forming galaxies, but with a distribution that is indistinguishable from the old quiescent population. We conclude that the morphological… Expand

The star formation histories of z ∼ 1 post-starburst galaxies
We present the star formation histories of 39 galaxies with high quality rest-frame optical spectra at 0.5<z<1.3 selected to have strong Balmer absorption lines and/or Balmer break, and compare to aExpand
The Colors and Sizes of Recently Quenched Galaxies: A Result of Compact Starburst before Quenching
We analyze the colors and sizes of 32 quiescent (UVJ-selected) galaxies with strong Balmer absorption (EW(Hδ) ≥ 4 A) at z ∼ 0.8 drawn from DR2 of the LEGA-C survey to test the hypothesis that theseExpand
Inverse stellar population age gradients of post-starburst galaxies at z = 0.8 with LEGA-C

Evolution of the cold gas properties of simulated post-starburst galaxies
Post-starburst galaxies are typically considered to be a transition population, en route to the red sequence after a recent quenching event. Despite this, recent observations have shown that theseExpand
Are All Post-starbursts Mergers? HST Reveals Hidden Disturbances in the Majority of PSBs
How do galaxies transform from blue, star-forming spirals to red, quiescent early-type galaxies? To answer this question, we analyzed a set of 26 gas-rich, shocked post-starburst galaxies with HubbleExpand
Stellar Metallicities and Elemental Abundance Ratios of z ∼ 1.4 Massive Quiescent Galaxies
The chemical composition of galaxies has been measured out to z~4. However, nearly all studies beyond z~0.7 are based on strong-line emission from HII regions within star-forming galaxies. MeasuringExpand

Abstract The spatial distribution of the dust and stars contains crucial information about the evolutionary pathways of galaxies. We present results of our study combing high-resolution ALMA and HSTExpand
Major Mergers Are Not the Dominant Trigger for High-accretion AGNs at z ∼ 2
Research over the past decade has shown diminishing empirical evidence for major galaxy mergers being a dominating or even important mechanism for the growth of supermassive black holes in galaxiesExpand
The diverse evolutionary pathways of post-starburst galaxies
About 35 years ago a class of galaxies with unusually strong Balmer absorption lines and weak emission lines was discovered in distant galaxy clusters1,2. These objects, alternatively referred to asExpand
