Hubble Ultra Deep Field-JD2: Mid-Infrared Evidence for a z ~ 2 Luminous Infrared Galaxy [PDF]
, 2007 The Hubble Ultra Deep Field source JD2 presented in Mobasher et al. is an unusual galaxy that is very faint at all wavelengths shortward of 1.1 μm. Photometric redshift fits to data between 0.4 and 8 μm yield a significant probability that it is an ...

HerS-3: An Exceptional Einstein Cross Reveals a Massive Dark Matter Halo
The Astrophysical JournalWe present a study of HerS-3, a dusty star-forming galaxy at z _spec = 3.0607, which is gravitationally amplified into an Einstein cross with a fifth image of the background galaxy seen at the center of the cross.

On the Very Bright Dropouts Selected Using the James Webb Space Telescope NIRCam Instrument
The Astrophysical JournalThe selection of candidate high-redshift galaxies using the dropout technique targeting the Lyman-break signature sometimes yields very bright objects that are too luminous to be easily explained if they are indeed at the expected redshifts.

Characterising Nearby Luminous Infrared Galaxies
, 2017 Luminous InfraRed Galaxies (LIRGs) in the local universe are known to be highly interacting galaxies with strong star-formation in obscured environments. LIRGs have diversity in terms of morphology and mode and location of SF, while their even more energetic counterparts, the Ultra-Luminous IR galaxies, ULIRGs, (LIR ≥ 10^12 Lsol ) are normally ...

NICMOS Observations of Interaction-triggered Star Formation in the Luminous Infrared Galaxy NGC 6090 [PDF]
, 1999 High-resolution 1.1, 1.6, and 2.2 μm imaging of the luminous infrared galaxy NGC 6090 obtained with NICMOS on the Hubble Space Telescope is presented. These new observations are centered on the two nuclei of the merger and reveal the spiral structure of ...

Energetic nuclear transients in luminous infrared galaxies
, 2022 There have been a number of observations of infrared (IR) echoes associated with tidal disruption events (TDEs). These arise as a result of re-radiation of the TDE s UV/optical photons by dust in the nuclear environment. Furthermore, there have been multiple fortuitous discoveries of IR echoes in the nuclei of luminous infrared galaxies (LIRGs) over ...

Quantification of the Age Dependence of Mid-infrared Star Formation Rate Indicators
The Astrophysical JournalWe 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 ...

GOALS-JWST: Gas Dynamics and Excitation in NGC 7469 Revealed by NIRSpec
The Astrophysical JournalWe present new JWST NIRSpec integral field spectroscopy (IFS) data for the luminous infrared galaxy NGC 7469, a nearby (70.6 Mpc) active galaxy with a Seyfert 1.5 nucleus that drives a highly ionized gas outflow and a prominent nuclear star-forming ring.
