Magnetization of the IGM by Starburst Dwarf Galaxies?

, 2011
It is well known that the intergalactic or intracluster medium (IGM, ICM) is pervaded by a weak magnetic field, along with a population of relativistic particles.

Formation and Evolution of E+A Galaxies in Dusty Starburst Galaxies

The Astrophysical Journal, 2001
The formation and evolution of the ``E+A'' (also named ``k+a'' and ``a+k'' types by Dressler et al. 1999) galaxies found in significant numbers in the cores of intermediate redshift clusters has been extensively discussed by many authors. In this paper, we model the spectral, dynamical and morphological evolution of a prime candidate for producing this

Densitometry and Thermometry of Starburst Galaxies

, 2011
With a goal toward deriving the physical conditions in external galaxies, we present a survey of formaldehyde (H2CO) and ammonia (NH3) emission and absorption in a sample of starburst galaxies using the Green Bank Telescope. By extending well-established

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.

Low Dust Mass and High Star Formation Efficiency at z > 12 from Deep ALMA Observations

The Astrophysical Journal
We investigate the dust mass buildup and star formation efficiency of two galaxies at z  > 12—GHZ2 and GS-z14-0—by combining Atacama Large Millimeter/submillimeter Array and JWST observations with an analytical model that assumes dust at thermal ...

H.E.S.S. observations of composite Seyfert–starburst galaxies

Astronomy & Astrophysics
Context. Composite galaxies that contain both Seyfert and starburst components may produce very high-energy (VHE; > 100 GeV) γ-ray emission at a wide range of spatial scales, from a few Schwarzschild radii of a supermassive black hole (SMBH; RS = 10−6 pc

Extreme star formation in starburst galaxies [PDF]

, 2007
Starburst galaxies undergo a phase of vigorous star formation. In these galaxies, gas is turned into stars at such a high rate, that the reservoir of available gas is quickly emptied.

SHELLQs-JWST Unveils the Host Galaxies of 12 Quasars at z > 6

The Astrophysical Journal
The advent of the James Webb Space Telescope (JWST) has opened new horizons in the study of quasar host galaxies during the reionization epoch ( z  > 6).

Spatially Resolved Spectroscopy of Starburst and Post-Starburst Galaxies in the Rich z ∼0.55 Cluster CL 0016+16

, 2010
We have used the Low Resolution Imaging Spectrograph on the W. M. Keck I telescope to obtain spatially resolved spectroscopy of a small sample of six ‘post-starburst’ and three ‘dusty-starburst’ galaxies in the rich cluster CL 0016+16 at z=0.55.
