THE NATURE OF STARBURSTS. II. THE DURATION OF STARBURSTS IN DWARF GALAXIES [PDF]
The Astrophysical Journal, 2010 The starburst phenomenon can shape the evolution of the host galaxy and the surrounding intergalactic medium. The extent of the evolutionary impact is partly determined by the duration of the starburst, which has a direct correlation with both the amount of stellar feedback and the development of galactic winds, particularly for smaller mass dwarf ...

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

Starbursts in barred spiral galaxies [PDF]
Astronomy and Astrophysics Supplement Series, 1998 This paper presents optical long-slit spectroscopic observations of 105 barred Markarian IRAS galaxies. These observations are used to determine the spectral type of emission-line regions in the nucleus and along the bar of the galaxies, in order to define a homogeneous sample of Starburst Nucleus Galaxies (SBNGs). Our selection criteria have been very

Methods for identifying high‐redshift galaxy cluster candidates
Astronomische 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.

Estimation of the detected background by the future gamma ray transient mission CAMELOT
Astronomische Nachrichten, Volume 340, Issue 7, Page 666-673, August 2019., 2019 Abstract This study presents a background estimation for the CubeSats Applied for MEasuring and LOcalising Transients (CAMELOT), which is a proposed fleet of nanosatellites for the all‐sky monitoring and timing‐based localization of gamma ray transients with precise localization capability at low Earth orbits.

The History of Starburst Galaxies [PDF]
, 2001 Dusty galaxies with luminosities in excess of 10^11 solar luminosities have been detected out to redshifts of about unity by the Infrared Space Observatory (ISO), and to higher redshifts using millimetre(mm)- and submm-wave cameras on ground-based telescopes.

Chimneys in the starburst galaxy M 82 [PDF]
Symposium - International Astronomical Union, 1999 A new radio image of the core of the starburst galaxy M82 is presented. A pair of probable galactic chimneys are evident. Such structures have been conjectured to result when a giant shell of ionized gas breaks out of the dense plane of a galaxy and ejects hot gas into the halo.

Star Formation Law at Sub‐kpc Scale in the Elliptical Galaxy Centaurus A as Seen by ALMA
Advances in Astronomy, Volume 2017, Issue 1, 2017., 2017 We present an extensive analysis of the relationship between star formation rate surface density (∑SFR) and molecular gas surface density (∑H2) at sub‐kpc scale in the elliptical galaxy Centaurus A (also known as NGC 5128) at the distance 3.8 Mpc. 12CO (J = 2‐1) data from Atacama Large Millimetre/Sub‐Millimetre Array SV data with very high resolution ...

The Observer’s Guide to the Gamma‐Ray Burst Supernova Connection
Advances in Astronomy, Volume 2017, Issue 1, 2017., 2017 We present a detailed report of the connection between long‐duration gamma‐ray bursts (GRBs) and their accompanying supernovae (SNe). The discussion presented here places emphasis on how observations, and the modelling of observations, have constrained what we know about GRB‐SNe.
