Mid-Infrared Spectral Diagnostics of Luminous Infrared Galaxies [PDF]

The Astrophysical Journal, 2010
We present a statistical analysis of the mid-infrared (MIR) spectra of 248 luminous infrared (IR) galaxies (LIRGs) which comprise the Great Observatories All-sky LIRG Survey (GOALS) observed with the Infrared Spectrograph (IRS) on-board the Spitzer Space

A Spitzer Study of Interacting Luminous and Ultra-Luminous Infrared Galaxies [PDF]

Proceedings of the International Astronomical Union, 2012
We conducted a Spitzer Space Telescope survey of 28 Luminous (11 < log(LIR/L_odot) < 12, LIRGs) and Ultra-Luminous Infrared Galaxies (log(LIR/L_odot) > 12, ULIRGs).

AKARI Near-Infrared Spectroscopy of Luminous Infrared Galaxies [PDF]

The Astrophysical Journal, 2012
We present the AKARI near-infrared (NIR; 2.5-5 micron) spectroscopic study of 36 (ultra)luminous infrared galaxies [(U)LIRGs] at z=0.01-0.4. We measure the NIR spectral features including the strengths of 3.3 micron polycyclic aromatic hydrocarbon (PAH ...

The Role of AGN in Luminous Infrared Galaxies from the Multiwavelength Perspective

Universe, 2022
Galaxy mergers provide a mechanism for galaxies to effectively funnel gas and materials toward their nuclei and fuel the central starbursts and accretion of supermassive black holes.

Dynamical Masses in Luminous Infrared Galaxies [PDF]

The Astrophysical Journal, 2006
We have studied the dynamics and masses of a sample of ten nearby luminous and ultraluminous infrared galaxies (LIRGS and ULIRGs), using 2.3 micron CO absorption line spectroscopy and near-infrared H- and Ks-band imaging.

NICMOS Imaging of Infrared-Luminous Galaxies [PDF]

The Astronomical Journal, 1999
We present near-infrared images obtained with the HST NICMOS camera for a sample of 9 luminous (LIGs: L_IR (8-1000 microns) >~ 10^11 L_sun) and 15 ultra-luminous (ULIGS: L_IR >~ 10^12 L_sun) infrared galaxies.

Evolution of the ISM in luminous infrared galaxies [PDF]

Astronomy and Astrophysics, 2010
Aims. Molecules that trace the high-density regions of the interstellar medium may be used to evaluate the changing physical and chemical environment during the ongoing nuclear activity in (ultra-) luminous infrared galaxies (ULIRGs).Methods. The changing ratios of the HCN (1-0), HNC (1-0), HCO(+) (1-0), CN (1-0) and CN (2-1), and CS (3-2) transitions ...

z-GAL – A Comprehensive Redshift Survey of the Brightest Herschel Galaxies [PDF]

EPJ Web of Conferences, 2022
We here introduce z-GAL, a Large Program using NOEMA, aimed at a comprehensive 3 and 2-mm spectroscopic redshift survey of a large sample of 137 bright (S500μm > 80mJy) Herschel-selected high-z dusty star forming galaxies, probing the peak of cosmic ...

Warm Molecular Gas in the Central Parsecs of the Buried Nucleus of NGC 4418 Traced with the Fundamental CO Rovibrational Absorptions

The Astrophysical Journal, 2023
We investigated the inner buried nucleus of a nearby luminous infrared galaxy, NGC 4418, using high-resolution spectroscopy of fundamental carbon monoxide (CO) rovibrational absorptions around 4.67 μ m for the first time.
