Red Post-Starburst Galaxies

Astrophysics and Space Science, 1994
Observations of nearby star-forming regions suggest that the initial mass function is deficient in low-mass stars when the ambient star formation rate is high. We investigate the consequences of a truncated initial mass function on the photometric evolution of star burst galaxies using new models of stellar population synthesis. A major prediction with

Starburst galaxies – An observer’s view

Astrophysics and Space Science, 2004
Starbursts are the most efficient producers of metals in the Universe at low redshifts. They produce enough energy to drive outflows of material from their disks. This makes them important objects to study in order to understand the chemical evolution not only of the interstellar medium (ISM) in the starburst galaxies themselves, but also of the ...

The starburst galaxy NGC1808: another M82?

Astrophysics and Space Science, 1994
An optical polarization map of the starburst galaxy NGC1808 shows that on kpc scales there is a coherent galactic magnetic field which follows the spiral arms on the galaxy. The inner 750pc surrounding the central region shows characteristics of a huge reflection nebula illuminated by the various hotspots within the starburst.

Dusty starburst galaxies in the early Universe as revealed by gravitational lensing

Nature, 2013
In the past decade, our understanding of galaxy evolution has been revolutionized by the discovery that luminous, dusty starburst galaxies were 1,000 times more abundant in the early Universe than at present.

A massive, cooling-flow-induced starburst in the core of a luminous cluster of galaxies

Nature, 2012
In the cores of some clusters of galaxies the hot intracluster plasma is dense enough that it should cool radiatively in the cluster’s lifetime, leading to continuous ‘cooling flows’ of gas sinking towards the cluster centre, yet no such cooling flow has

Starburst Galaxies: An Infrared Perspective

2005
The infrared regime is a key range for studies of starburst galaxies. It contains a rich variety of tracers of the gas, dust, and star-formation activity and enables us to probe deep into dust-enshrouded star-forming regions. Selected results based on diagnostics at near and mid-infrared wavelengths are highlighted.

Surveys of Starburst Galaxies

1997
A brief review of IRAS galaxy redshift surveys is given. The evolution of starburst galaxies is discussed and a detailed model for source-counts from radio to X-rays is outlined. The role of starbursts in the Hubble Deep Field is explored.

Starbursts in interacting galaxies

2008
We first review the evidence for IR activity in interacting and merging galaxies, based on 10 and 20 µm observations. We then investigate the ‘starbursts vs. monsters’ explanations for the energy source powering the IR activity in these galaxies. Using available IR photometry, and IR, optical, and ultraviolet spectroscopy, we show that, in general, a ...
