A search for candidate radio supernova remnants in the nearby irregular starburst galaxies NGC 4214 and NGC 4395 [PDF]

open access: yesSerbian Astronomical Journal, 2005
We present the results of a search for new candidate radio su­pernova remnants (SNRs) in the nearby starburst irregular galaxies NGC 4214 and NGC 4395 using archived radio observations made with the Very Large Array (VLA) at the wavelengths of 3.5 cm, 6 ...

Low-luminosity AGN and Normal Galaxies [PDF]

open access: yes, 2000
Low-luminosity AGN (with X-ray luminosity < 1e42 ergs/s) far outnumber ordinary AGN, and are therefore perhaps more relevant to our understanding of AGN phenomena and the relationship between AGN and host galaxies.

Large turbulent reservoirs of cold molecular gas around high-redshift starburst galaxies [PDF]

open access: yesNature, 2017
Starburst galaxies at the peak of cosmic star formation are among the most extreme star-forming engines in the Universe, producing stars over about 100 million years (ref. 2).

An Explanation for the Overrepresentation of Tidal Disruption Events in Post-starburst Galaxies

open access: yesThe Astrophysical Journal, 2023
Tidal disruption events (TDEs) provide a valuable probe for studying the dynamics of stars in the nuclear environments of galaxies. Recent observations show that TDEs are strongly overrepresented in post-starburst or “green valley” galaxies, although the

Current Star Formation in Post-Starburst Galaxies? [PDF]

open access: yes, 2001
Radio continuum observations are a probe of star formation in galaxies, and are unaffected by dust extinction. Observations of the distant rich cluster Cl 0939+4713 have detected radio galaxies classified as post-starburst (``k+a'') on the basis of their

The evolution of post-starburst galaxies from z=2 to 0.5 [PDF]

open access: yes, 2016
We present the evolution in the number density and stellar mass functions of photometrically selected post-starburst galaxies in the UKIDSSUltraDeep Survey,with redshifts of 0.5 10.

SYNCHRONIZED FORMATION OF STARBURST AND POST-STARBURST GALAXIES IN MERGING CLUSTERS OF GALAXIES [PDF]

open access: yesThe Astrophysical Journal, 2010
We propose that synchronized triggering of star formation in gas-rich galaxies is possible during major mergers of cluster of galaxies, based on new numerical simulations of the time evolution of the physical properties of the intracluster medium (ICM) during such a merger event.

DIRECT DETECTION OF LYMAN CONTINUUM ESCAPE FROM LOCAL STARBURST GALAXIES WITH THE COSMIC ORIGINS SPECTROGRAPH [PDF]

open access: yes, 2016
We report on the detection of Lyman continuum radiation in two nearby starburst galaxies. Tol 0440-381, Tol 1247-232, and Mrk 54 were observed with the Cosmic Origins Spectrograph on board the Hubble Space Telescope.

Methods for identifying high‐redshift galaxy cluster candidates

open access: yesAstronomische Nachrichten, Volume 340, Issue 7, Page 618-621, August 2019., 2019
Abstract Recent theories linked long gamma ray bursts (GRBs) to galaxies with rapid star formation or starburst; thus, we expect that long GRBs (LGRBs) are more frequent in midcluster galaxies where mergers and tidal interactions between gas‐rich galaxies are more likely to occur. Yet there is no galaxy cluster known to be associated with LGRBs.

Starburst radio galaxies: general properties, evolutionary histories and triggering [PDF]

open access: yes, 2010
In this paper we discuss the results of a programme of spectral synthesis modelling of a sample of starburst radio galaxies in the context of scenarios for the triggering of the activity and the evolution of the host galaxies.
