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

open access: yesThe 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 ...

A Spitzer/IRS Study of Local Luminous Infrared Galaxies

open access: yes, 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.

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

open access: yesThe 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.

Pahs, Ionized Gas, and Molecular Hydrogen in Brightest Cluster Galaxies of Cool Core Clusters of Galaxies

open access: yes, 2011
We present measurements of 5-25 {\mu}m emission features of brightest cluster galaxies (BCGs) with strong optical emission lines in a sample of 9 cool-core clusters of galaxies observed with the Infrared Spectrograph on board the Spitzer Space Telescope.

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

open access: yesThe 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

JADES: Resolving the Stellar Component and Filamentary Overdense Environment of Hubble Space Telescope (HST)-dark Submillimeter Galaxy HDF850.1 at z = 5.18

open access: yesThe Astrophysical Journal
HDF850.1 is the brightest submillimeter galaxy (SMG) in the Hubble Deep Field. It is known as a heavily dust-obscured star-forming galaxy embedded in an overdense environment at z = 5.18.

Shockingly Effective: Cluster Winds as Engines of Feedback in Starburst Galaxy VV 114

open access: yesThe Astrophysical Journal
We present high-resolution Keck Cosmic Web Imager and MUSE integral field unit spectroscopy of VV 114, a local IR-luminous merger undergoing a vigorous starburst and showing evidence of galactic-scale feedback. The high-resolution data allow for spectral

The mid-infrared emission of local Luminous Infrared Galaxies

open access: yes, 2006
En este art´ıculo se combinan la sensibilidad de Spitzer y la alta resolucion espacial de T-ReCS en el GeminiSouth para estudiar las propiedades en el infrarrojo (IR) medio de galaxias luminosas infrarrojas (LIRGs) locales (d < 75 Mpc). Las im´agenes de T-ReCS en 8 − 10 µm nos han permitido separar la emision nuclear (formacion estelar y/o AGN) de la ...

Possibility of Using 3.3 μm Polycyclic Aromatic Hydrocarbon Luminosity as a Molecular Gas Mass Estimator

open access: yesThe Astrophysical Journal
We present CO(1–0) observations of 50 star-forming galaxies at 0.01 < z < 0.35, for which 3.3 μ m polycyclic aromatic hydrocarbon (PAH) emission flux or its upper limit is available.
