Star Formation in QSO Host Galaxies

, 2006
Many of the conditions that are necessary for starbursts appear to be important in the triggering of QSOs. However, it is still debatable whether starbursts are ubiquitously present in galaxies harboring QSOs.

The infrared luminosity of retired and post-starburst galaxies: A cautionary tale for star formation rate measurements

The Open Journal of Astrophysics
In galaxies with significant ongoing star formation there is an impressively tight correlation between total infrared luminosity (L${\mathstrut}_{TIR}$) and H$\alpha$ luminosity (L${\mathstrut}_{H\alpha}$), when H$\alpha$ is properly corrected for ...

Dissecting the γ-Ray Emissions of the Nearby Galaxies NGC 1068 and NGC 253

The Astrophysical Journal
Intrigued by recent high-energy study results for nearby galaxies with γ -ray emission and in particular NGC 1068 that has been detected as a neutrino-emitting source by the IceCube Neutrino Observatory, we conduct a detailed analysis of the γ -ray data ...

Can Supernovae Quench Star Formation in High-z Galaxies?

The Astrophysical Journal
JWST is providing a unique opportunity to directly study the feedback processes regulating star formation (SF) in early galaxies. The two z > 5 quiescent systems (JADES-GS-z7-01-QU and MACS0417-z5BBG) detected so far show a recent starburst after which ...

Resolving the Nuclear Environments of Tidal Disruption Event Host Galaxies within 45 pc

The Astrophysical Journal
Using Hubble Space Telescope/Space Telescope Imaging Spectrograph observations, we present the highest-spatial-resolution spectroscopic study to date of four tidal disruption event (TDE) host galaxies, with the best observed being the post-starburst host

On the Origins of Starburst and Post-Starburst Galaxies in Nearby Clusters

, 1998
HST WFPC2 images in B (F450W) and I (F814W) have been obtained for three starburst (SB) and two post-starburst (PSB) galaxies in the Coma cluster, and for three such galaxies in the cluster DC2048-52.

Strong Scatterings Invalidate Proposed Models of Enhanced Tidal Disruption Event Rates in Post-starburst Galaxies

The Astrophysical Journal
Stars wandering too close to supermassive black holes (SMBHs) can be ripped apart by the tidal forces of the black hole. Recent optical surveys have revealed that E+A galaxies are over-represented by a factor of ∼30, while green galaxies are over ...

Do Red Galaxies Form More Stars than Blue Galaxies?

The Astrophysical Journal
A new model is proposed in which typical galaxies form most of their stellar mass in a phase with an intrinsically red stellar population. In the standard picture, galaxies with intrinsically red stellar populations are believed to have old stellar ...
