The properties of discrete X-ray sources in star-forming galaxies [PDF]
, 2012 Observations of starburst galaxies have revealed a large number of point-like X-ray sources located within these systems, including active galactic nuclei (AGN), X-ray binaries (XRBs), and utraluminous X-ray sources (ULXs).

An investigation of the active galaxies M82 and NGC 5128 [PDF]
, 1995 In this thesis we present multi-waveband imaging polarimetry and spectropolarime- try of the starburst galaxy M82 and multi-waveband imaging polarimetry of the active galaxy NGC 5128. A review of previous studies of these galaxies is given.

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

The star formation history of early-type galaxies in the fornax cluster [PDF]
, 1998 We have measured central line strengths and line-strength gradients for a complete sample of early-type galaxies in the Fornax cluster, comprising 11 elliptical and 11 lenticular galaxies, more luminous than M(_B) = -17.

Modelling the UV to sub-mm SED of starburst galaxies
, 2015 This paper reviews the theoretical modelling of starburst galaxies with particular emphasis on the importance of the gas-phase physics in determining the form of the continuum SED and the emission line spectrum.

Star formation and molecular gas properties of post-starburst galaxies
, 2023 Post-starburst galaxies are believed to be in a rapid transition between major merger starbursts and quiescent ellipticals. Their optical spectrum is dominated by A-type stars, suggesting a starburst that was quenched recently. While optical observations

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
