Winds and Outflows in Starburst Galaxies and AGN [PDF]

Symposium - International Astronomical Union, 2004
Winds and outflows in starburst galaxies and AGN provide important information on the physics of the ‘central engine’, the presence and evolution of (nuclear) starbursts, and the metal enrichment of the nuclear environment and the intergalactic medium.

Post-starburst galaxies and the transformation of blue into red galaxies [PDF]

, 2016
We present deep single-dish radio observations of a sample of nearby post-starburst galaxies (0.05 < z < 0.1). About 50% of these post-starburst galaxies are detected at 21 cm, with H I masses of ~109M⊙, up to ~1010M⊙.

Starburst Galaxies in Their Last Billion Years: An Hδ Absorption Line Selected Sample

The Astrophysical Journal
In this paper, we focus on the study of starburst galaxies in their final billion years. Our galaxy selection is based solely on the presence of the H δ absorption line, which permits the later evolution of starburst galaxies to be traced, coinciding ...

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.

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,

Local starburst galaxies and their descendants

, 2016
Aims. 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. We also

First Detection of CO Isotopologues in a High-redshift Main-sequence Galaxy: Evidence of a Top-heavy Stellar Initial Mass Function

The Astrophysical Journal
Recent observations and theories have presented a strong challenge to the universality of the stellar initial mass function (IMF) in extreme environments. A notable example has been found for starburst conditions, where evidence favors a top-heavy IMF, i.

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 ...

Starburst galaxies as seen by gamma-ray telescopes [PDF]

, 2016
Starburst galaxies have a highly increased star-formation rate compared to regular galaxies and inject huge amounts of kinetic power into the interstellar medium via supersonic stellar winds, and supernova explosions.
