Imaging of Ultraluminous Infrared Galaxies in the Near-UV

open access: yes, 2000
We present the first ground-based U' (3410 angstroms) images of Ultraluminous Infrared Galaxies (ULIGs). Strong U' emission (median total M_U' = -20.8) is seen in all systems and in some cases the extended tidal features (both the smooth stellar distribution and compact star-forming features) contribute up to 60-80% of the total flux.

Discovery of Powerful Multivelocity Ultrafast Outflows in the Starburst Merger Galaxy IRAS 05189–2524 with XRISM

open access: yesThe Astrophysical Journal Letters
We observed the X-ray-bright ultraluminous infrared galaxy IRAS 05189−2524 with XRISM during its performance verification phase. The unprecedented energy resolution of the onboard X-ray microcalorimeter revealed complex spectral features at ∼7–9 keV ...

Local Ultraluminous Infrared Galaxies and Quasars

open access: yes, 2006
This paper reviews the recent results from a comprehensive investigation of the most luminous mergers in the local universe, the ultraluminous infrared galaxies (ULIRGs) and the quasars. First, the frequency of occurrence and importance of black hole driven nuclear activity in ULIRGs are discussed using the latest sets of optical, near-infrared, mid ...

A catalog to unite them all: REGALADE, a revised galaxy compilation for the advanced detector era

open access: yesAstronomy & Astrophysics
Context. Many applications in transient science, gravitational wave follow-up, and galaxy population studies require all-sky galaxy catalogs with reliable distances, extents, and stellar masses.

Observations of Ultraluminous Infrared Galaxies with the IRS on Spitzer [PDF]

open access: yes, 2006
We present spectra taken with the Infrared Spectrograph on Spitzer covering the 5−38μm region of the ten Ultraluminous Infrared Galaxies (ULIRGs) found in the IRAS Bright Galaxy Sample.

Evidence of a Forming Nucleus in the Fourcade–Figueroa Galaxy

open access: yesThe Astrophysical Journal
We analyze data from the IRAS, Wide-field Infrared Survey Explorer, and Planck satellites, revealing an unresolved dust condensation at the center of the Fourcade–Figueroa galaxy (ESO270-G017), which may correspond to a forming nucleus.

Systematic Study of the Inner Structure of Molecular Tori in Nearby U/LIRGs Using Velocity Decomposition of CO Rovibrational Absorption Lines

open access: yesThe Astrophysical Journal
Determining the inner structure of the molecular torus around an active galactic nucleus is essential for understanding its formation mechanism. However, spatially resolving the torus is difficult because of its small size.

A z ≃ 0.4 Galaxy Reflecting the High-redshift Little Red Dots: An Extended Starburst with an Overmassive Black Hole

open access: yesThe Astrophysical Journal
One of the most remarkable discoveries of JWST is a population of compact, red sources at z > 4, commonly referred to as Little Red Dots (LRDs). Spectroscopic identifications reported that most LRDs are active galactic nuclei, which are preferentially ...

Exploring the star formation histories of galaxies [PDF]

open access: yes, 1999
In this thesis, I explore the star formation histories of both spiral and elliptical galaxies. In Part 1,1 present an in-depth study of the star formation histories of spiral galaxies with a wide range of properties. Optical and near-infrared colours are
