The interaction-driven starburst contribution to the cosmic star formation rate density
, 2013 An increasing amount of observational evidence supports the notion that there are two modes of star formation: a quiescent mode in disk-like galaxies, and a starburst mode, which is generally interpreted as driven by merging.

THE RADIO–GAMMA CORRELATION IN STARBURST GALAXIES [PDF]
, 2015 We present a systematic study of non-thermal electron–proton plasma and its emission processes in starburst galaxies in order to explain the correlation between the luminosity in the radio band and the recently observed gamma luminosity.

The Astrophysical JournalRecent observations at low redshift have revealed that some post-starburst galaxies retain significant molecular gas reservoirs despite low ongoing star formation rates, challenging most theoretical predictions that rely on heating or expelling gas ...

The Earliest Stage of Galactic Star Formation
The Astrophysical Journal Letters, 2023 Using a recently developed technique to estimate gas temperatures ( T _SF ) in star-forming regions from large photometric surveys, we propose a diagram, analogous to the Hertzsprung–Russell diagram for individual stars, to probe the evolution of ...

Post-starburst quasars: bridging the gap between post-starburst galaxies and quasars [PDF]
, 2015 In order to better understand the nature of post-starburst quasars (PSQs) in the context of galaxy evolution, we compare their properties to those of post-starburst galaxies and quasars from appropriately selected samples possessing similar redshift ($z \

Cosmic axion background propagation in galaxies
Physics Letters B, 2016 Many extensions of the Standard Model include axions or axion-like particles (ALPs). Here we study ALP to photon conversion in the magnetic field of the Milky Way and starburst galaxies. By modelling the effects of the coherent and random magnetic fields,

, 2009 We investigate the fraction of starbursts, starburst-AGN composites, Seyferts, and LINERs as a function of infrared luminosity (L_IR) and merger progress for ~500 infrared-selected galaxies. Using the new optical classifications afforded by the extremely

On the Origins of Starburst and Poststarburst Galaxies in Nearby Clusters [PDF]
The Astronomical Journal, 1999 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. V (F555W) and I images for an additional PSB galaxy in Coma have been extracted from the archive. Seven of these galaxies were previously classified as E/

HIGH-J CO VERSUS FAR-INFRARED RELATIONS IN NORMAL AND STARBURST GALAXIES [PDF]
, 2015 We present correlations between 9 CO transitions ( J = 4 – 3 ?> to 12 – 11 ?> ) and beam-matched far-infrared (far-IR) luminosities ( L FIR , b ?> ) among 167 local galaxies, using Herschel Spectral and Photometric Imaging Receiver Fourier Transform ...
