The near-infrared morphology of ultraluminous infrared galaxies [PDF]

open access: yesThe Astrophysical Journal, 1990
Near-infrared images at 1.25, 1.65, and 2.2 microns have been obtained of nine galaxies from the IRAS Bright Galaxy Sample with infrared luminosities greater than 10 to the 12th solar luminosities. Two of the 2.2-micron images reveal previously undetected double nuclei, increasing the number of close double nuclei known for this samples from two to ...

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.

From SN 2010da to NGC 300 ULX-1: Ten Years of Observations of an Unusual High Mass X-Ray Binary in NGC 300 [PDF]

open access: yes, 2020
In May 2010, an intermediate luminosity optical transient was discovered in the nearby galaxy NGC 300 by a South African amateur astronomer. In the decade since its discovery, multi-wavelength observations of the misnamed “SN 2010da” have continually ...

The Cosmic History of Black Hole Growth from Deep Multiwavelength Surveys

open access: yesAdvances in Astronomy, Volume 2012, Issue 1, 2012., 2012
Significant progress has been made in the last few years on understanding how supermassive black holes form and grow. In this paper, we begin by reviewing the spectral signatures of active galactic nuclei (AGN) ranging from radio to hard X‐ray wavelengths.

Structural and Morphological Properties of Ultraluminous Infrared Galaxies at 1 < z < 3

open access: yesOpen Astronomy, 2015
Using the Hubble Space Telescope (HST)/Wide Field Camera 3 (WFC3) near-infrared high-resolution imaging from the 3D-HST survey, we analyze the morphology and structure of 502 ultraluminous infrared galaxies (ULIRGs; LIR > 1012L⊙) at 1 < z < 3. Their rest-

The Circumnuclear Environment of IRAS 20551‐4250: A Case Study of AGN/Starburst Connection for JWST

open access: yesAdvances in Astronomy, Volume 2012, Issue 1, 2012., 2012
We present a general review of the current knowledge of IRAS 20551‐4250 and its circumnuclear environment. This Ultraluminous Infrared Galaxy is one of the most puzzling sources of its class in the nearby Universe: the near‐IR spectrum is typical of a galaxy experiencing a very intense starburst, but a highly obscured active nucleus is identified ...

A Practical Guide to the Massive Black Hole Cosmic History

open access: yesAdvances in Astronomy, Volume 2012, Issue 1, 2012., 2012
I review our current understanding of massive black hole (MBH) formation and evolution along the cosmic history. After a brief introductory overview of the relevance of MBHs in the hierarchical structure formation paradigm, I discuss the main viable channels for seed BH formation at high redshift and for their subsequent mass growth and spin evolution.
