Properties of Ly-alpha emitters around the radio galaxy MRC 0316-257

open access: yes, 2005
Observations of the radio galaxy MRC 0316-257 at z=3.13 and the surrounding field are presented. Using narrow- and broad-band imaging obtained with the VLT, 77 candidate Ly-alpha emitters with a rest-frame equivalent width of > 15 A were selected in a ~7'

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

open access: yesAstronomische 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 ...

Phytochemical Profiling and Characterization of Honeydew, Cantaloupe, and Galia Melon Peel Extracts for Potential Prebiotic Activities

open access: yesFood Science &Nutrition, Volume 14, Issue 3, March 2026.
Bioactive compounds are recovered from Honeydew, Cantaloupe, and Galia melon peels through aqueous and ethanolic extraction followed by freeze‐drying. The resulting extracts undergo comprehensive characterization using HPLC, FTIR, and NMR spectroscopy to define their chemical profiles.

The Cosmic Owl: Twin Active Collisional Ring Galaxies with Starburst Merging Front at z = 1.14

open access: yesThe Astrophysical Journal
Galaxy mergers play a critical role in driving galaxy evolution, especially by transforming galaxy morphology, redistributing gas around galaxies, triggering active galactic nuclei (AGN), and stimulating star formation.

Exploring the galaxy cluster-group transition regime at high redshifts: Physical properties of two newly detected z > 1 systems

open access: yes, 2011
Context: Multi-wavelength surveys for clusters of galaxies are opening a window on the elusive high-redshift (z>1) cluster population. Well controlled statistical samples of distant clusters will enable us to answer questions about their cosmological ...

Akkermansia muciniphila enhances chicken resistance to infectious bronchitis virus by boosting GABA synthesis and suppressing the NF‐κB inflammatory pathway

open access: yesiMetaOmics, Volume 3, Issue 1, March 2026.
Infectious bronchitis virus (IBV) represents a major threat to poultry production, with current control strategies offering limited protection. In this study, we demonstrate gut microbiome is a critical determinant of IBV resistance using fecal microbiota transplantation.

Clinical Application of Peripheral Blood Biomarkers for Solid Tumors

open access: yesMedComm, Volume 7, Issue 3, March 2026.
Peripheral blood biomarkers provide a minimally invasive, dynamic, and potentially more accurate means to obtain a comprehensive tumor profile. Technologies for detecting them are advancing, and with the help of artificial intelligence, they are being used more and more often for cancer diagnosis, prognostic assessment, and therapeutic monitoring ...
