Wolf–Rayet stars in starburst galaxies [PDF]

New Astronomy Reviews, 2000
Wolf-Rayet stars have been detected in a large number of galaxies experiencing intense bursts of star formation. All stars initially more massive than a certain, metallicity-dependent, value are believed to experience the Wolf-Rayet phase at the end of their evolution, just before collapsing in supernova explosion.

Local starburst galaxies and their descendants. Statistics from the Sloan Digital Sky Survey [PDF]

, 2015
Despite strong interest in the starburst phenomenon in extragalactic astronomy, the concept remains ill-defined. Here we use a strict definition of starburst to examine the statistical properties of starburst galaxies in the local universe.

COSMOS-Web: The Role of Galaxy Interactions and Disk Instabilities in Producing Starbursts at z < 4

The Astrophysical Journal
We study of the role of galaxy–galaxy interactions and disk instabilities in producing starburst activity in galaxies out to z = 4. For this, we use a sample of 387 galaxies with robust total star formation rate measurements from Herschel, gas masses ...

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,

Spectral Properties of Some IRAS Starburst Galaxies at HI 21-cm statistic study [PDF]

مجلة جامعة الانبار للعلوم الصرفة, 2012
Many research deal with physical properties of HI gas in all types of galaxies.The 21cm data analysis allows to measure spectral and radio properties for galaxies, so it allows to study physical operation that assistant in starformation. We interest here

UV excess galaxies: Wolf-Rayet galaxies [PDF]

, 2000
We discuss V and R band photometry for 67% of the Sullivan et al. 2000 SA57 ultraviolet-selected galaxy sample. In a sample of 176 UV-selected galaxies, Sullivan et al.

The Nature of Starburst Galaxies

The Astrophysical Journal, 1996
Utilizing a large sample of infrared-selected starburst galaxies having optical images and long-slit spectra, we explore the interrelationships between the properties of starbursts and relate these properties to those of the "host" galaxy. We find that the half-light radius of the Hα-emitting region (re, Hα) enters into several correlations that ...

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 ...

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 Mitchell Spectrograph: Studying Nearby Galaxies with the VIRUS Prototype

Advances in Astronomy, Volume 2013, Issue 1, 2013., 2013
The Mitchell Spectrograph (a.k.a. VIRUS‐P) on the 2.7 m Harlan J. Smith telescope at McDonald Observatory is currently the largest field of view (FOV) integral field unit (IFU) spectrograph in the world (1.7′ × 1.7′). It was designed as a prototype for the highly replicable VIRUS spectrograph which consists of a mosaic of IFUs spread over a 16 ...
