LOFAR Detection of Post-starburst Galaxies

Research Notes of the AAS, 2023
Abstract We report detection of 104 radio counterparts in a sample of 1204 Sloan Digital Sky Survey-detected post-starburst (PSB) galaxies using the 144 MHz LOw-Frequency ARray (LOFAR) Two-meter Sky Survey Data Release 2 (LoTSS2). The detection rate of optically selected PSB galaxies in the 144 MHz images is ∼8.6% while that in the 1.4 ...

CO-Observations of Post-Starburst Galaxies

Astrophysics and Space Science, 2001
The so-called starburst phenomenon is an issue of great importance for the evolution of galaxies. Although a lot of progress has been made in this field, it is still unknown how they evolve.

The Typical Massive Quiescent Galaxy at z ∼ 3 is a Post-starburst [PDF]

The Astrophysical Journal Letters, 2020
Abstract We have obtained spectroscopic confirmation with Hubble Space Telescope WFC3/G141 of a first sizeable sample of nine quiescent galaxies at 2.4 < z < 3.3. Their average near-UV/optical rest-frame spectrum is characterized by low attenuation (AV ∼ 0.6 mag) and a strong Balmer break, larger than the 4000 Å ...

Post-Starburst Galaxies in Clusters from the GASP Survey. [PDF]

, 2022
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

Star formation and molecular gas properties of post-starburst galaxies [PDF]

, 2023
Post-starburst galaxies are believed to be in a rapid transition between major merger starbursts and quiescent ellipticals. Their optical spectrum is dominated by A-type stars, suggesting a starburst that was quenched recently. While optical observations

Evolution Through the Post-starburst Phase: Using Post-starburst Galaxies as Laboratories for Understanding the Processes that Drive Galaxy Evolution [PDF]

Publications of the Astronomical Society of the Pacific, 2021
Post-starburst (or "E+A") galaxies trace the fastest and most dramatic processes in galaxy evolution. Recent work studying the evolution of galaxies through this phase have revealed insights on how galaxies undergo structural and stellar population changes as well as the role of various feedback mechanisms.

Post-starburst Galaxies in the Centers of Intermediate-redshift Clusters

The Astrophysical Journal, 2022
Abstract We present results from MUSE spatially resolved spectroscopy of 21 post-starburst galaxies in the centers of eight clusters from z ∼ 0.3 to z ∼ 0.4. We measure spatially resolved star formation histories (SFHs), the time since quenching (t Q ), and the fraction of stellar

AGB populations in post-starburst galaxies [PDF]

Astronomy & Astrophysics, 2014
In a previous paper we compared the SEDs of a sample of 808 K+A galaxies from the FUV to the MIR to the predictions of the spectrum synthesis models explicitly using AGB components. Here we use the new AGB-light models from C. Maraston (including less fuel for the later stages of stellar evolution and improved calibrations) to address the discrepancies

Growth of Accreting Supermassive Black Hole Seeds and Neutrino Radiation

Journal of Astrophysics, Volume 2015, Issue 1, 2015., 2015
In the framework of microscopic theory of black hole (MTBH), which explores the most important processes of rearrangement of vacuum state and spontaneous breaking of gravitation gauge symmetry at huge energies, we have undertaken a large series of numerical simulations with the goal to trace an evolution of the mass assembly history of 377 plausible ...
