Stellar populations of local infrared-selected galaxies

, 2009
International audienceThe stellar populations of 849 local infrared-selected galaxies from SDSS and IRAS (including 419 star-forming galaxies, 326 composite galaxies, 35 Seyfert 2s, and 69 LINERs in 4 spectral classes) are studied by using STARLIGHT ...

Characterizing the Molecular Gas in Infrared Bright Galaxies with CARMA

The Astrophysical Journal
We present the CO(1–0) maps of 28 infrared-bright galaxies from the Great Observatories All-Sky Luminous Infrared Galaxy Survey (GOALS) taken with the Combined Array for Research in Millimeter Astronomy (CARMA).

Star Clusters in the Near-ultraviolet-optical-near-infrared: Spectral Energy Distribution Modeling with Direct Markers of Gas and Dust Emission

The Astrophysical Journal
The large number of star clusters in nearby galaxies permits us to statistically test the predictions of stellar, dust, and gas models. Using Hubble Space Telescope (HST) broadband plus H α imaging combined with JWST near-infrared imaging, we use a total

Near-infrared diagnostic diagrams of the gas ionization sources in nearby galaxies: A JWST NIRSpec view

Astronomy & Astrophysics
Context. Tracing the origin of the gas emission lines in galaxies can prove challenging in certain cases. Buried active galactic nuclei (AGNs) and obscured young stellar clusters pose significant obstacles with respect to traditional optical diagnostic ...

A JWST MIRI LRS Survey of 37 Massive Star-forming Galaxies and Active Galactic Nuclei at Cosmic Noon: Overview and First Results

The Astrophysical Journal
We present a large spectroscopic survey with JWST’s Mid-Infrared Instrument Low Resolution Spectrometer (LRS) targeting 37 infrared-bright galaxies between z  = 0.65–2.46 with infrared luminosities $\mathrm{log}{L}_{{\rm{IR}}}/{L}_{\odot }\gt 11.5$ and $\

CHARACTERIZING ULTRAVIOLET AND INFRARED OBSERVATIONAL PROPERTIES FOR GALAXIES. II. FEATURES OF ATTENUATION LAW

, 2014
Variations in the attenuation law have a significant impact on observed spectral energy distributions for galaxies. As one important observational property for galaxies at ultraviolet and infrared wavelength bands, the correlation between infrared-to ...

Surface photometry of early-type galaxies in rich clusters [PDF]

, 1998
This thesis investigates the morphology of early-type galaxies in two rich clusters using 2D surface photometry. In particular, the amount of light in the 'disk' component is focussed upon, as the presence of a disk is the main morphological criterion in
