Spectroscopy of Luminous Infrared Galaxies [PDF]

open access: yesSymposium - International Astronomical Union, 1999
A review of recent optical and infrared spectroscopic results on luminous infrared galaxies is presented. The main emphasis is on the ultraluminous objects. Possible correlations with infrared luminosity are identified. These results are used to constrain the nature of the dominant energy source in luminous infrared galaxies, and to test whether these ...

Fading AGNs in Poststarburst Galaxies

open access: yesThe Astrophysical Journal, 2023
The role of active galactic nuclei (AGNs) in quenching galaxies and driving the evolution from star forming to quiescence remains a key question in galaxy evolution.

A Diverse Population of z ∼ 2 ULIRGs Revealed by JWST Imaging

open access: yesThe Astrophysical Journal, 2023
Four ultraluminous infrared galaxies (ULIRGs) observed with JWST/NIRcam in the Cosmos Evolution Early Release Science program offer an unbiased preview of the z ∼ 2 ULIRG population.

GOALS-JWST: Resolving the Circumnuclear Gas Dynamics in NGC 7469 in the Mid-infrared

open access: yesThe Astrophysical Journal Letters, 2022
The nearby, luminous infrared galaxy NGC 7469 hosts a Seyfert nucleus with a circumnuclear star-forming ring and is thus the ideal local laboratory for investigating the starburst–AGN (active galactic nucleus) connection in detail.

High-Resolution Mid-Infrared Imaging of Infrared-Luminous Starburst Galaxies [PDF]

open access: yesThe Astronomical Journal, 2001
Observations for seven infrared luminous starburst galaxies are reported in the mid-infrared from 8 - 18 microns using the Keck Telescopes with spatial resolution approaching the diffraction limit. All of the galaxies observed show evidence of strong interactions based on optical morphologies.

Two Candidates for Dual AGN in Dwarf-dwarf Galaxy Mergers

open access: yesThe Astrophysical Journal, 2023
Dual active galactic nuclei (DAGN) are important for understanding galaxy-merger-triggered fueling of black holes and the hierarchical growth of structures.

Silicates in Ultraluminous Infrared Galaxies

open access: yesThe Astrophysical Journal, 2008
We analyze the mid-infrared (MIR) spectra of ultraluminous infrared galaxies (ULIRGs) observed with the Spitzer Space Telescope's Infrared Spectrograph. Dust emission dominates the MIR spectra of ULIRGs, and the reprocessed radiation that emerges is independent of the underlying heating spectrum.

Infrared magnitude–redshift relations for luminous radio galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2002
Infrared magnitude-redshift relations for the 3CR and 6C samples of radio galaxies are presented for a wide range of plausible cosmological models, including those with non-zero cosmological constant OmegaLambda. Variations in the galaxy formation redshift, metallicity and star formation history are also considered.

A Comprehensive Study of Galaxies at z ∼ 9–16 Found in the Early JWST Data: Ultraviolet Luminosity Functions and Cosmic Star Formation History at the Pre-reionization Epoch

open access: yesThe Astrophysical Journal Supplement Series, 2023
We conduct a comprehensive study on dropout galaxy candidates at z ∼ 9–16 using the first 90 arcmin ^2 James Webb Space Telescope (JWST) Near Infrared Camera images taken by the early release observations (ERO) and early release science programs.
