Normal Galaxies in the Infrared [PDF]
, 2007 This review addresses what can be learned from infrared observations about galaxies powered predominantly by star formation. Infrared techniques mostly probe the interstellar medium of galaxies, yielding physical and chemical information on the medium out of which stars form, which is in turn affected by those stars.

The Search for Very High Energy γ-rays from Misaligned AGN [PDF]
, 2013 The aim of this work is to study the potential for emission at very high energies (100 GeV) by misaligned active galactic nuclei (AGN) and the future prospects for observations of these objects with the next generation imaging atmospheric Cherenkov ...

The middle infrared properties of OH megamaser host galaxies
, 2014 We compiled all 119 OH maser galaxies (110 out of them are megamasers, i.e., L-OH > 10 L-circle dot) published so far and cross-identified these OH masers with the Wide-Field Infrared Survey Explorer (WISE) catalog, to investigate the middle infrared ...

Constraining dark energy using real and mock galaxy surveys [PDF]
, 2009 In this thesis, we study how dark energy may be constrained by measurements of large-scale clustering in future galaxy surveys, and through the imprint of a time-varying large-scale potential on the CMB (the integrated Sachs-Wolfe effect).

Near-infrared imaging of interacting galaxies
The Astrophysical Journal, 1990 Galaxy-galaxy interactions are known to cause dramatic changes in morphology and at the same time often induce large bursts of star formation activity. While optical images are sufficient to reveal the overall morphological peculiarities of these systems, they suffer from several problems, the greatest of which is obscuration by dust within the ...

Dissecting Starburst Galaxies with Infrared Observations [PDF]
, 2005 The infrared regime contains a number of unique diagnostic features for probing the astrophysics of starburst galaxies. After a brief summary of the most important tracers, we focus in detail on the use of emission lines to probe the upper part of the main sequence in a young superstarcluster in the Antennae, and the compact, dusty starburst in the ...

Near-infrared surface photometry of a sample of barred galaxies [PDF]
, 2007 We have obtained deep J and Ks images of a sample of nine barred galaxies in order to collect a reliable and homogeneous set of images to which N-body simulations of barred galaxies will be compared.

Global properties of infrared bright galaxies
The Astrophysical Journal Supplement Series, 1989 Infrared flux densities of 182 galaxies, including 50 galaxies in the Virgo cluster, were analyzed using IRAS data for 12, 25, 60, and 100 microns, and the results were compared with data listed in the Point Source Catalog (PSC, 1985). In addition, IR luminosities, L(IRs), colors, and warm dust masses were derived for these galaxies and were compared ...

Chemical and kinematical evolution in nearby dwarf spheroidal galaxies [PDF]
, 2006 Dwarf spheroidal (dSph) galaxies are the least massive and luminous objects known to exist. These galaxies are often considered as the fossil building blocks of massive systems predicted by some cosmological models.
