Mapping dark matter in the Bullet Cluster using JWST imaging and spectroscopy

Astronomy & Astrophysics
Context. The Bullet Cluster (1E 0657–56), located at a redshift of 0.296, is among the best-known merging galaxy clusters and a key laboratory for dark matter studies.

MORPHOLOGICAL TYPES OF 254 RICH PF GALAXY CLUSTERS

Odessa Astronomical Publications, 2014
We determined the morphological types for 254 rich galaxy clusters from the PF Catalogue of Galaxy Clusters and Groups. The data set contains the PF galaxy clusters, which have no ACO coinciding ones.

A C‐repeat binding factor–salicylic acid (CBF–SA) module links wound‐induced evaporative cooling to tissue repair in plants

New Phytologist, EarlyView.
A model of the C‐repeat binding factor–salicylic acid (CBF–SA) module in plant wound healing. Summary Repairing damaged tissues is essential for the survival of all organisms. In plants, tissue injury rapidly triggers defense and repair programs. However, the molecular mechanisms linking early injury cues to the later stage of wound repair remain ...

Spectral Energy Distribution Fitting of Globular Clusters in NGC 4874: Masses and Metallicities

The Astrophysical Journal
In most nearby galaxies, photometry of the integrated light of their globular clusters (GCs) has been obtained in only two filters, yielding just a single color index.

Utopia Remembers: The Soviet Past in the Imagined Communist Future

The Russian Review, EarlyView.
Abstract After a twenty‐five‐year hiatus, the reappearance of utopian literature in 1957 prompted Soviet literary watchdogs to corral the subgenre into an ideologically‐acceptable mold. A key requirement was for future generations to be depicted as reverently commemorating the past.

Radial kinematics of brightest cluster galaxies [PDF]

, 2008
This is the first of a series of papers devoted to the investigation of a large sample of brightest cluster galaxies (BCGs), their kinematic and stellar population properties, and the relationships between those and the properties of the cluster. We have

A Solar Analog Model for Decrease in Far Ultraviolet Irradiance Under a Grand Minimum

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Solar analog field stars having a range of magnetic activity can provide an estimate of solar spectral irradiance (SSI) variability relevant to understanding the Sun's influence on terrestrial climate. This approach is particularly useful for far ultraviolet (FUV) irradiance that cannot be observed from the Earth surface.

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 ...

BRIGHTEST CLUSTER GALAXIES AND CORE GAS DENSITY IN REXCESS CLUSTERS [PDF]

The Astrophysical Journal, 2010
We investigate the relationship between brightest cluster galaxies (BCGs) and their host clusters using a sample of nearby galaxy clusters from the Representative XMM Cluster Structure Survey (REXCESS). The sample was imaged with the Southern Observatory for Astrophysical Research (SOAR) in R band to investigate the mass of the old stellar population ...
