Origin of Radio Emission in Three Nearby Ultraluminous Infrared Galaxies with Signatures of Luminous Buried Active Galactic Nuclei

The Astrophysical Journal
We report multifrequency Very Long Baseline Array (VLBA) observations at 2.3 and 8.4 GHz of three nearby ultraluminous infrared galaxies, identified via mid-infrared spectroscopic analyses as hosting deeply embedded active galactic nuclei (AGNs ...

Spectroscopic Constraints on the Mid-infrared Attenuation Curve. I. Attenuation Model Using Polycyclic Aromatic Hydrocarbon Emission

The Astrophysical Journal
We introduce a novel model to spectroscopically constrain the mid-infrared (MIR) extinction/attenuation curve from 3–17 μ m, using polycyclic aromatic hydrocarbon (PAH) emission drawn from an AKARI–Spitzer extragalactic cross-archival data set. Currently

Spectropolarimetric search for hidden active galactic nuclei in four southern ultraluminous infrared galaxies

, 2003
We report on a spectropolarimetric analysis of four southern ultraluminous infrared galaxies (ULIRGs), aimed at constraining the presence of hidden broad active galactic nucleus (AGN) lines.

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

The 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.

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

The 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.
