Stellar population analysis on local infrared-selected galaxies

, 2009
International audienceAims: We study the stellar population of local infrared galaxies, which contain star-forming galaxies, composite galaxies, LINERs, and Seyfert 2s.

Infrared images of merging galaxies

, 1990
Infrared imaging of interacting galaxies is especially interesting because their optical appearance is often so chaotic due to extinction by dust and emission from star formation regions, that it is impossible to locate the nuclei or determine the true ...

Infrared spectroscopy of star formation in galaxies

, 1987
The Brackett alpha and beta lines with 7.2 seconds angular and 350 km/s velocity resolution were observed in 11 infrared-bright galaxies. From these measurements extinctions, Lyman continuum fluxes, and luminosities due to OB stars were derived.

X-ray emission from star-forming galaxies [PDF]

, 2011
In this dissertation we study the properties of high-mass X-ray binaries (HMXBs) and hot inter-stellar medium in star-forming galaxies and their relation with the star formation rate (SFR), based on the data from Chandra, Spitzer, GALEX and 2MASS public ...

CO in infrared luminous galaxies

, 1988
There has been considerable recent interest in the properties of infrared galaxies due to the discovery by the Infrared Astronomical Satellite (IRAS) of a class of luminous galaxies which emit the bulk of their energy in the far-infrared (Houck et al ...

Far-infrared properties of optically-selected quasars and Seyfert galaxies

, 1987
Pointed IRAS observations and ground based observations are used to determine the infrared properties of optically selected galaxies and quasars. The use of complete, unbiased, optically selected samples means that statistical tests can be applied to ...

Far-infrared properties of cluster galaxies

, 1987
Far-infrared properties are derived for a sample of over 200 galaxies in seven clusters: A262, Cancer, A1367, A1656 (Coma), A2147, A2151 (Hercules), and Pegasus.

Increasing AGN sample completeness using long-term near-infrared variability

In this work, we use 8 years of deep near-infrared imaging to select and study a new set of 601 active galaxies identified through long-term near-infrared (NIR) variability in the UKIDSS Ultra Deep Survey (UDS).
