Spitzer mid-infrared spectroscopy of 70 μm-selected distant luminous infrared galaxies [PDF]

, 2008
We present mid-infrared spectroscopy obtained with the Spitzer Space Telescope of a sample of 11 optically faint, infrared luminous galaxies selected from a Spitzer MIPS 70 μm imaging survey of the NDWFS Boötes field.

A Spitzer/IRS Study of Local Luminous Infrared Galaxies

, 2010
We present the first results of our program to study a sample of local luminous infrared galaxies (LIRGs, L_IR = 10^11-10^12 L_sun) with the Spitzer infrared spectrograph (IRS). In these proceedings we investigate the behavior of the 9.7 um silicate feature in LIRGs.

UGC 2369S: A Kiloparsec-scale Triple Merger Candidate Identified in a Nearby Luminous Infrared Galaxy

The Astrophysical Journal
We present high-spatial-resolution (≲1 $\mathop{.}\limits{^{\prime\prime} }$ 0), multiwavelength observations of UGC 2369S, a nearby luminous infrared galaxy showing three distinct cores separated on kiloparsec scales in near-infrared (NIR) imaging with ...

Comparison of dust-to-gas ratios in luminous, ultraluminous, and hyperluminous infrared galaxies

, 2007
19 pages+ 7 figures. in press in ANInternational audienceThe dust-to-gas ratios in three different samples of luminous, ultraluminous, and hyperluminous infrared galaxies are calculated by modelling their radio to soft X-ray spectral energy distributions

An ALMA Spectroscopic Survey of the Brightest Submillimeter Galaxies in the SCUBA-2-COSMOS Field (AS2COSPEC): Physical Properties of z = 2–5 Ultra- and Hyperluminous Infrared Galaxies

The Astrophysical Journal
We report the physical properties of the 18 brightest ( S _870 _μ _m = 12.4–19.2 mJy) and not strongly lensed 870 μ m–selected dusty star-forming galaxies (DSFGs), also known as submillimeter galaxies (SMGs), in the COSMOS field.

Quantification of the Age Dependence of Mid-infrared Star Formation Rate Indicators

The Astrophysical Journal
We combine James Webb Space Telescope images of the nearby galaxy NGC 5194 in the hydrogen recombination line Pa α (1.8756 μ m) from the Cycle 1 program JWST-FEAST with 21 μ m dust continuum images from the Cycle 2 Treasury program JWGT to quantify the ...

Over half of the far-infrared background light comes from galaxies at z ≥ 1.2 [PDF]

, 2009
Submillimetre surveys during the past decade have discovered a population of luminous, high-redshift, dusty starburst galaxies¹⁻⁸. In the redshift range 1 ≤ z ≤ 4, these massive submillimetre galaxies go through a phase characterized by optically ...

The Evolution of the Size and Merger Fraction of Submillimeter Galaxies across 1 < z ≲ 6 as Observed by JWST

The Astrophysical Journal
Precise tracking of the growth in galaxy size and the evolution of merger fractions with redshift is vital for understanding the formation history of submillimeter galaxies (SMGs). This study investigates this evolution over a broad redshift range (1
