Context. Galaxies may suffer some starburst and quenched periods in their history due to galaxy mergers and feedback. However, semi-numerical simulations of the Epoch of Reionization (EoR) do not accurately model the effects of the star formation history

Post-starburst galaxies in the COSMOS field at z < 0.45

open access: yes
Post-starburst galaxies (PSBs) are key to understanding how galaxies transition from active star formation to quiescence. We identify 36 PSBs by spectroscopic selection in the COSMOS field at z < 0.45.

Spatially resolved star-formation histories of local post-starburst galaxies: Starburst and quenching spatial patterns consistent with recent mergers

open access: yes
Post-starburst (PSB) galaxies, having recently experienced a starburst followed by rapid quenching, are excellent laboratories to probe physical mechanisms that drive starbursts and shutting down of star formation. Integral-field spectroscopy reveals the

Population Models for Star Formation Timescales in Early Galaxies: The First Step toward Solving Outshining in Star Formation History Inference

open access: yesThe Astrophysical Journal
James Webb Space Telescope (JWST) has revealed temporarily quenched and ultraviolet-luminous galaxies in the early Universe, suggesting enhanced star formation stochasticity. Verifying this hypothesis is critical yet challenging.

A Tale of Tails: Star Formation and Stripping in Jellyfish Galaxies in the Strong Lensing Cluster MACS J0138.0-2155

open access: yesThe Open Journal of Astrophysics
We investigate the effects of ram-pressure stripping on four galaxies within the massive, strong-lensing cluster MACS-J0138.0-2155 ($z=0.336$). Of these, three are classified as jellyfish galaxies, with significant elongated tails. Two of these jellyfish

Quiescent Host Galaxies of Extended Quasars Revealed by Spectrophotometric Decomposition

open access: yesThe Astrophysical Journal
Previous works of low-redshift quasar host galaxies have focused on compact quasars and found that their host galaxies are mainly star-forming galaxies.

Post-Starburst Galaxies in Clusters from the GASP Survey.

open access: yes, 2018
Post-starburst galaxies, also known as k+a galaxies, show no sign of emission lines and prominent Balmer absorption lines in their spectra. They are in a transitional phase between the star forming and the passive galaxies. I present here the study of a

New Methods for Tracking Galaxy and Black Hole Evolution Using Post-Starburst Galaxies

open access: yes, 2017
Galaxies in transition from star-forming to quiescence are a natural laboratory for exploring the processes responsible for this evolution. Using a sample of post-starburst galaxies identified to have recently experienced a recent burst of star formation
