Extragalactic gamma-ray background from AGN winds and star-forming galaxies in cosmological galaxy formation models [PDF]
, 2017 We derive the contribution to the extragalactic gamma-ray background (EGB) from AGN winds and star-forming galaxies by including a physical model for the gamma-ray emission produced by relativistic protons accelerated by AGN-driven and supernova-driven ...

Starbursts in interacting galaxies: Observations and models [PDF]
Starbursts have been a puzzling field of research for more than a decade. It is evident that they played a significant role in the evolution of many galaxies but still quite little is known about the starburst mechanisms.

Galaxies and Photometric Signature of Starburst [PDF]
Symposium - International Astronomical Union, 1996 In a series of papers (see Rakos & Schombert 1995, ApJ 439, 47), we have carried out CCD photometry of galaxies in rich clusters at various redshifts. We use a modified Strömgren system, modified in the sense that the filter set is “redshifted” to the cluster of galaxies in consideration (i.e., λobs = λ(1 + z), therefore no k-correction).

The Global Schmidt law in star forming galaxies [PDF]
, 1997 Measurements of Hα, H I, and CO distributions in 61 normal spiral galaxies are combined with published far-infrared and CO observations of 36 infrared-selected starburst galaxies, in order to study the form of the global star formation law over the full ...

The Astrophysical JournalPolycyclic aromatic hydrocarbon (PAH) dust emission has been proposed as an effective extinction-independent star formation rate (SFR) indicator in the mid-infrared, but this may depend on conditions in the interstellar medium.

The Flux Ratio Method for Determining the Dust Attenuation of Starburst Galaxies
, 1999 The presence of dust in starburst galaxies complicates the study of their stellar populations as the dust's effects are similar to those associated with changes in the galaxies' stellar age and metallicity.

The Astrophysical Journal, 1989 New multiaperture 1.65 and 2.2 micron photometry has been obtained for the central region of 132 spirals exhibiting 2 orders of magnitude range in central 10-micron luminosity. This multiaperture photometry along with optical spectroscopy indicated that the high central 10-micron luminosity (about 1 billion solar luminosities) is powered by massive ...

The equipartition magnetic field formula in starburst galaxies: accounting for pionic secondaries and strong energy losses [PDF]
, 2013 Equipartition arguments provide an easy way to find a characteristic scale for the magnetic field from radio emission, by assuming the energy densities in cosmic rays and magnetic fields are the same.
