Mid-Infrared Diagnostics of LINERs [PDF]

, 2006
We report results from the first mid-infrared spectroscopic study of a comprehensive sample of 33 LINERs, observed with the Spitzer Space Telescope. We compare the properties of two different LINER populations: infrared-faint LINERs, with LINER emission ...

Luminous Infrared Galaxies in a Merging Sequence: ISO Observations [PDF]

Symposium - International Astronomical Union, 1999
We report mid-infrared images of several luminous infrared galaxies (LIGs) taken with ISOCAM on the Infrared Space Observatory (ISO). These LIGs were chosen to represent different phases of a merger sequence of galaxy-galaxy interaction with special emphasis on early/intermediate stages of merging.

The HST Large Programme on NGC 6752 ‐ V. Differences in luminosity and mass function among stellar populations

Astronomische Nachrichten, Volume 345, Issue 5, June 2024.
Abstract We exploit the astro‐photometric dataset of the multi‐epoch infrared parallel field of a Hubble Space Telescope Large Programme aimed at studying the faintest stars of the globular cluster NGC 6752 to determine the luminosity and mass functions of the multiple stellar populations of this cluster. Thanks to the measurement of proper motions and

Warm Molecular Gas in the Central Parsecs of the Buried Nucleus of NGC 4418 Traced with the Fundamental CO Rovibrational Absorptions

The Astrophysical Journal, 2023
We investigated the inner buried nucleus of a nearby luminous infrared galaxy, NGC 4418, using high-resolution spectroscopy of fundamental carbon monoxide (CO) rovibrational absorptions around 4.67 μ m for the first time.

ChAInGeS: The Chandra Arp Interacting Galaxies Survey

, 2011
We have conducted a statistical analysis of the ultra-luminous X-ray point sources (ULXs; L(X) >= 10^39 erg/s) in a sample of galaxies selected from the Arp Atlas of Peculiar Galaxies.

Pairing statistics for infrared-luminous galaxies

The Astronomical Journal, 1993
A knowledge of the pairing fraction of IR-selected galaxies is important in understanding the role of interactions in star formation and nuclear activity. It is clear that interactions are extremely common among the most IR-luminous systems, but results have been inconsistent for less luminous systems; this may result from using peculiar morphology as ...

A MULTIPLY IMAGED LUMINOUS INFRARED GALAXY BEHIND THE BULLET CLUSTER (1E0657-56) [PDF]

, 2008
We present evidence for a Spitzer-selected luminous infrared galaxy (LIRG) behind the Bullet Cluster (1E0657-56). The galaxy, originally identified as a multiply imaged source using Infrared Array Camera (IRAC) photometry, has a spectral energy ...

Heavy Elements and Electromagnetic Transients from Neutron Star Mergers

Annalen der Physik, Volume 536, Issue 2, February 2024.
Astro‐(physics) has made major leaps forward through the combined information provided by both gravitational waves and electromagnetic emission from the first detected neutron star merger event. This review provides an up‐to‐date overview of today's understanding of neutron star mergers and their electromagnetic emission and it discusses possible ...
