Accuracy of the Photometric Redshifts of Brightest Cluster Galaxies Identified in the CFHTLS-W1

Journal of Advanced Research in Natural and Applied Sciences
We determine the accuracy of photometric redshifts for the brightest cluster galaxies (BCGs) identified in the W1 field of the Canada-France-Hawaii Telescope Legacy Survey (CFHTLS).

Investigating Galactic Cosmic Ray Ionization’s Contribution to Aerosol Formation on Neptune and a Potential Link to the Relationship Between Brightness and Solar Activity

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract In this work we investigate how ionization from Galactic Cosmic Rays (GCRs) can affect aerosol nucleation on Neptune and discuss potential implications for the observed brightness variations that appear to follow the solar cycle. We calculate the planetary vertical cutoff rigidity for Neptune based on the O8 ${\mathrm{O}}_{8}$ magnetic field ...

Genomic Insights Into the Multimetal Resilience and Biofilm‐Templated Nanorod Biosynthesis of Stenotrophomonas bentonitica BII‐R7: Bioremediation and Green Nanotechnology Implications

Microbial Biotechnology, Volume 19, Issue 9, September 2026.
Biofilm extracellular polymeric substances (EPS) in Stenotrophomonas bentonitica BII‐R7 direct the formation of crystalline trigonal selenium nanorods. Comparative genomics identifies a unique genetic toolkit underpinning EPS composition and metal resilience, positioning this strain as a platform for bioremediation and green nanomaterial synthesis ...

Visual Icons

Philosophy and Phenomenological Research, Volume 113, Issue 2, Page 327-345, September 2026.
ABSTRACT Philosophers often characterize perception as image‐like. There is little agreement, however, about what constitutes an imagistic or iconic representation. This article identifies five signature properties of iconic representations endorsed in the philosophical and scientific literature: item‐richness, feature‐richness, spatiotemporal ...

Brightest cluster galaxies and the intracluster light

In this chapter, we delve into the formation and primary characteristics of two significant components within galaxy clusters: the brightest cluster galaxies (BCGs) and the intracluster light (ICL). Drawing upon recent and pertinent studies in the field, we explore the mechanisms driving their growth from high redshift to the present day, i.e., mergers

The Shape of the Chameleon Fifth-Force on the Mass Components of Galaxy Clusters

Universe
In the context of chameleon gravity, we present a semi-analytical solution of the chameleon field profile in an accurately modelled galaxy cluster’s mass components, namely the stellar mass of the Brightest Cluster Galaxy (BCG), the baryonic mass in ...

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.
