Fading AGNs in Poststarburst Galaxies

The 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.

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

AIP Conference Proceedings, 2010
We present a statistical analysis of 248 luminous infrared galaxies (LIRGs) which comprise the Great Observatories All‐sky LIRG Survey (GOALS) observed with the Infrared Spectrograph (IRS) on‐board Spitzer in the rest‐frame wavelength range between 5 and 38 μm.

Star-formation histories of local luminous infrared galaxies [PDF]

Astronomy & Astrophysics, 2015
We present the analysis of the integrated spectral energy distribution (SED) from the ultraviolet (UV) to the far-infrared and H$ $ of a sample of 29 local systems and individual galaxies with infrared (IR) luminosities between 10^11 Lsun and 10^11.8 Lsun.

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

The 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.
