AKARINEAR-INFRARED SPECTROSCOPY OF LUMINOUS INFRARED GALAXIES [PDF]

open access: yesThe Astrophysical Journal, 2012
We present the AKARI near-infrared (NIR; 2.5-5 micron) spectroscopic study of 36 (ultra)luminous infrared galaxies [(U)LIRGs] at z=0.01-0.4. We measure the NIR spectral features including the strengths of 3.3 micron polycyclic aromatic hydrocarbon (PAH) emission and hydrogen recombination lines (Br .

ChAInGeS: The Chandra Arp Interacting Galaxies Survey

open access: yes, 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.

The differential magnification of high-redshift ultraluminous infrared galaxies [PDF]

open access: yes, 1998
A class of extremely luminous high-redshift galaxies has recently been detected in unbiased submillimetre-wave surveys using the Submillimetre Common-User Bolometer Array (SCUBA) camera at the James Clerk Maxwell Telescope.

Vision at high latitudes: High sensitivity without specific boreal adaptations in photoreception in reindeer (Rangifer tarandus L.)

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The light climate at high latitudes, in particular the extended twilight of winter and the reduced diel variation in light level in midsummer and midwinter, potentially constrains visual function and the synchronisation of temporal organisation in polar species. In this

The mid-infrared emission of local Luminous Infrared Galaxies

open access: yesRevista Mexicana De Astronomia Y Astrofisica, 2006
En este art´ıculo se combinan la sensibilidad de Spitzer y la alta resolucion espacial de T-ReCS en el GeminiSouth para estudiar las propiedades en el infrarrojo (IR) medio de galaxias luminosas infrarrojas (LIRGs) locales (d < 75 Mpc). Las im´agenes de T-ReCS en 8 − 10 µm nos han permitido separar la emision nuclear (formacion estelar y/o AGN) de la ...

Neutral Gas Outflows and Inflows in Infrared-Faint Seyfert Galaxies

open access: yes, 2009
Previous studies of the Na I D interstellar absorption line doublet have shown that galactic winds occur in most galaxies with high infrared luminosities.

Decomposing Star Formation and Active Galactic Nucleus with Spitzer Mid-Infrared Spectra: Luminosity Functions and Co-Evolution [PDF]

open access: yes, 2010
We present Spitzer 7-38um spectra for a 24um flux limited sample of galaxies at z~0.7 in the COSMOS field. The detailed high-quality spectra allow us to cleanly separate star formation (SF) and active galactic nucleus (AGN) in individual galaxies.

Review of asteroid, meteor, and meteorite‐type links

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 4, Page 928-973, April 2025.
Abstract With the goal to determine the origin of our meteorites in the asteroid belt, video and photographic observations of meteors have now tracked 75 meteorite falls. Six years ago, there were just hints that different meteorite types arrived on different orbits, but now, the number of orbits (N) is high enough for distinct patterns to emerge.

Unveiling the Distant Universe: Characterizing z ≥ 9 Galaxies in the First Epoch of COSMOS-Web

open access: yesThe Astrophysical Journal
We report the identification of 15 galaxy candidates at z ≥ 9 using the initial COSMOS-Web JWST observations over 77 arcmin ^2 through four Near Infrared Camera filters (F115W, F150W, F277W, and F444W) with an overlap with the Mid-Infrared Imager (F770W)

Two Candidates for Dual AGN in Dwarf-dwarf Galaxy Mergers

open access: yesThe Astrophysical Journal, 2023
Dual active galactic nuclei (DAGN) are important for understanding galaxy-merger-triggered fueling of black holes and the hierarchical growth of structures.
