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.

Energetic nuclear transients in luminous and ultraluminous infrared galaxies [PDF]

Astronomy & Astrophysics, 2022
Energetic nuclear outbursts have been discovered in luminous and ultraluminous infrared galaxies (U/LIRGs) at unexpectedly high rates. To investigate this population of transients, we performed a search in mid-IR data from the Wide-field Infrared Survey Explorer (WISE) satellite and its NEOWISE survey to detect and characterise luminous and smoothly ...

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

The 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.

Asca Observations of Luminous Infrared Starburst Galaxies [PDF]

Symposium - International Astronomical Union, 1999
We present recent results of X-ray observations of two luminous infrared galaxies, NGC3690+IC694 (Arp299) and NGC1614 obtained by the Japanese X-ray astronomical satellite ASCA. Both galaxies have quite high infrared luminosity (> 1011L⊙) and strong evidence of merger.

Probing Cool and Warm Infrared Galaxies using Photometric and Structural Measures [PDF]

, 2006
We have analyzed a sample of nearby cool and warm infrared (IR) galaxies using photometric and structural parameters. The set of measures include far-infrared color ($C = \log_{10}[S_{60\mu m}/S_{100\mu m}]$), total IR luminosity ($L_{TIR}$), radio ...

A Significant Population of Very Luminous Dust-Obscured Galaxies at Redshift z ~ 2 [PDF]

, 2008
Observations with Spitzer Space Telescope have recently revealed a significant population of high-redshift z~2 dust-obscured galaxies (DOGs) with large mid-IR to UV luminosity ratios.

The Accretion History of AGN: The Spectral Energy Distributions of X-Ray-luminous Active Galactic Nuclei

The Astrophysical Journal, 2023
Spectral energy distributions (SEDs) from X-ray to far-infrared (FIR) wavelengths are presented for a sample of 1246 X-ray-luminous active galactic nuclei (AGNs; L _0.5–10 keV > 10 ^43 erg s ^−1 ), with z _spec < 1.2, selected from Stripe 82X, COSMOS ...

Resolved CO(1–0) Emission and Gas Properties in Luminous Dusty Star-forming Galaxies at z = 2–4

The Astrophysical Journal, 2023
We present the results of a survey of CO(1−0) emission in 14 infrared luminous dusty star-forming galaxies (DSFGs) at 2 < z < 4 with the NSF’s Karl G. Jansky Very Large Array.

Disentangling Accretion Disk and Dust Emissions in the Infrared Spectrum of Type 1 AGN

Frontiers in Astronomy and Space Sciences, 2017
We use a semi-empirical model to reproduce the 0.1–10 μm spectral energy distribution (SED) of a sample of 85 luminous quasars. In the model, the continuum emission from the accretion disk as well as the nebular lines are represented by a single ...
