The UV-upturn in brightest cluster galaxies

, 2010
This paper is part of a series devoted to the investigation of a large sample of brightest cluster galaxies (BCGs), their properties and the relationships between these and the properties of the host clusters.

The Look-back Time Evolution of Far-Ultraviolet Flux from the Brightest Cluster Elliptical Galaxies at z < 0.2 [PDF]

, 2007
We present the GALEX UV photometry of the elliptical galaxies in Abell clusters at moderate redshifts (z < 0.2) for the study of the look-back time evolution of the UV upturn phenomenon. The brightest elliptical galaxies (M_r < -22) in 12 remote clusters

Brightest Cluster Galaxy Alignments in Merging Clusters [PDF]

The Astrophysical Journal, 2019
Abstract The orientations of brightest cluster galaxies (BCGs) and their host clusters tend to be aligned, but the mechanism driving this is not clear. To probe the role of cluster mergers in this process, we quantify alignments of 38 BCGs in 22 clusters undergoing major mergers (up to ∼1 Gyr after first pericenter).

Evaluation of the SWAN Game‐Based Approach to Re‐Building Numeracy Skills in Aphasia: Feasibility and Preliminary Findings

International Journal of Language &Communication Disorders, Volume 61, Issue 3, May/June 2026.
ABSTRACT Background Numeracy difficulties are common in individuals with post‐stroke aphasia, yet assessments and therapies addressing these are limited. This study investigated the feasibility and effectiveness of SWAN, a game‐based digital intervention targeting foundational number language skills: counting and transcoding.

A Catalog of 1.58 Million Clusters of Galaxies Identified from the DESI Legacy Imaging Surveys

The Astrophysical Journal Supplement Series
Based on the DESI Legacy Imaging Surveys released data and available spectroscopic redshifts, we identify 1.58 million clusters of galaxies by searching for the overdensity of the stellar mass distribution of galaxies within redshift slices around ...

Evaluating the Color of Chocolate Chip Cookies: Comparative Performance of Instrumental Colorimetry, Digital Image Analysis, and Computer Vision Relative to Human Perception

Journal of Food Science, Volume 91, Issue 5, May 2026.
ABSTRACT Food color is commonly quantified using colorimeters; however, these instruments may be impractical in home‐based or small‐scale production settings. More accessible alternatives, such as digital image analysis and computer vision, may offer reliable color quantification when conventional instrumentation is unavailable.

Investigating the M GCS–M h Relation in the Most Massive Galaxies

The Astrophysical Journal, 2023
The relation between the total mass contained in the globular clusters of a galaxy and the mass of its dark-matter halo has been found observationally to be nearly linear over five decades of mass.

Stellar formation in Brightest Cluster Galaxies [PDF]

Proceedings of the International Astronomical Union, 2009
AbstractWe study the interplay between stellar population of the Brightest Cluster Galaxies (BCG) and cluster global properties. We use X-ray properties from Chandra, ROSAT and ASCA observations and BCGs spectra from SDSS-DR6. Using STARLIGHT we determined the star formation history of the BCGs and look for relations with the intra-cluster gas ...

CI chondrite Oued Chebeika 002 links asteroids Bennu and Ryugu to common parent body

Meteoritics &Planetary Science, Volume 61, Issue 5, Page 801-818, May 2026.
Abstract CI chondrites are a compositionally primitive group of meteorites that have undergone extensive aqueous alteration, providing insights into the evolution of primitive planetesimals. Oued Chebeika 002 is the most pristine CI chondrite to date.
