The Early Ophthalmic Effects of Vatinoxan in Healthy Detomidine‐Sedated Horses

Veterinary Ophthalmology, Volume 29, Issue 4, July 2026.
ABSTRACT Objective To evaluate the short‐term ophthalmic effects of vatinoxan, a peripherally selective alpha2‐adrenoceptor antagonist, in detomidine‐sedated horses. Animals Studied Seven healthy horses without ophthalmic disease in a randomized, masked, two‐period crossover study design, with a ≥ 7‐day rest period.

Mapping the dynamics, star-formation rates, and chemical properties of galaxies with integral field spectroscopy [PDF]

, 2005
Major advances in the development of instruments for eight and ten meter class telescopes are revolutionising our understanding of galaxy formation. In particular, Integral Field Spectrographs (which produce a three dimensional {x, y, velocity) map of a ...

Repeating Nuclear Transients From Repeating Partial Tidal Disruption Events

Astronomische Nachrichten, Volume 347, Issue 5, June 2026.
ABSTRACT Extragalactic nuclear transients that exhibit repeating outbursts can be modeled as the repeated dynamical interaction between bound stars and supermassive black holes (SMBHs). A subset of these transients, with recurrence timescales of months‐to‐years, have been explained as accretion flares from the repeated tidal stripping of a star by an ...

Hidden No More: Spotlight on Tidal Disruption Events in Active Galactic Nuclei

Astronomische Nachrichten, Volume 347, Issue 5, June 2026.
ABSTRACT Tidal disruption events (TDEs) are typically discovered in previously quiescent galaxies. However, earlier studies have revealed a handful of TDEs occurring in pre‐existing active galactic nuclei (AGN). We discuss AT2019aalc, a promising TDE candidate in an AGN, and compare it to similar sources.

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

The 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)

Mid-Infrared Spectral Diagnostics of Luminous Infrared Galaxies [PDF]

AIP Conference Proceedings, 2010
We present a statistical analysis of 248 luminous infrared galaxies (LIRGs) which comprise the Great Observatories All‐sky LIRG Survey (GOALS) observed with the Infrared Spectrograph (IRS) on‐board Spitzer in the rest‐frame wavelength range between 5 and 38 μm.

Discovery and Initial Investigation of a New Low Surface Brightness Planetary Nebula Candidate at High Galactic Latitude

Astronomische Nachrichten, Volume 347, Issue 3, March 2026.
ABSTRACT Planetary nebulae represent a late evolutionary phase of low‐ to intermediate‐mass stars. In this article, we present the serendipitous discovery of a previously unknown, faint potential Galactic planetary nebula (PN) in the constellation Camelopardalis, identified during a survey‐inspection, aiming at the detection of dwarf companions of the ...

The clustering of galaxies in hierarchical galaxy formation models [PDF]

, 2010
Galaxy clustering encodes information about the values of cosmological parameters and also about the physical processes behind galaxy formation and evolution. The GALFORM semi-analytical model is the theoretical approach we used to model galaxy formation.

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 ...
