X-ray emission from clusters and groups of galaxies [PDF]

Proceedings of the National Academy of Sciences, 1998
Recent major advances in x-ray imaging and spectroscopy of clusters have allowed the determination of their mass and mass profile out to ≈1/2 the virial radius. In rich clusters, most of the baryonic mass is in the gas phase, and the ratio of mass in gas/stars varies by a factor of 2–4.

Characterization of Transcriptional, Epigenetic, and Phenotypic Plasticity and Discovery of Biomarkers in Acute and Chronic Murine Schistosomiasis Infection

The FASEB Journal, Volume 40, Issue 3, 15 February 2026.
Workflow for discovering parasitological and molecular changes related to Schistosoma mansoni infection. ABSTRACT Parasites can induce changes in their hosts, favoring the success of the infection and its development at each stage of their life cycle.

Genomic Resources for Imperiled Caribbean Reef‐Forming Corals (Hexacorallia: Scleractinia): Complete Mitochondrial Genomes of Dichocoenia stokesii, Diploria labyrinthiformis, Oculina patagonica, and Stephanocoenia intersepta

Ecology and Evolution, Volume 16, Issue 2, February 2026.
Mitochondrial genomes of imperiled Caribbean corals are sequenced. These genomic resources will support conservation initiatives. ABSTRACT Coral reefs provide a wide variety of services essential to both marine ecosystems and human societies yet reef‐forming corals are currently facing a multitude of global and local environmental stressors.

Hot Gas in Galaxy Groups: Recent Observations

, 2012
Galaxy groups are the least massive systems where the bulk of baryons begin to be accounted for. Not simply the scaled-down versions of rich clusters following self-similar relations, galaxy groups are ideal systems to study baryon physics, which is ...

The DEEP2 Galaxy Redshift Survey: Clustering of Groups and Group Galaxies atz ∼ 1

The Astrophysical Journal, 2006
We study the clustering properties of groups and of galaxies in groups in the DEEP2 Galaxy Redshift Survey dataset at z~1. Four clustering measures are presented: 1) the group correlation function for 460 groups with estimated velocity dispersions of sigma>200 km/s, 2) the galaxy correlation for the full galaxy sample, using a flux-limited sample of

Residual eDNA in eRNA Extracts Skews eRNA‐Based Biodiversity Assessment: Call for Optimised DNase Treatment

Molecular Ecology Resources, Volume 26, Issue 2, February 2026.
ABSTRACT Environmental RNA (eRNA) metabarcoding has rapidly emerged as a powerful tool for assessing contemporary biodiversity patterns across diverse ecosystems. However, the potential for false positive detections caused by co‐extracted environmental DNA (eDNA) remains unquantified.

The evolution of the star formation activity per halo mass up to redshift ~1.6 as seen by Herschel [PDF]

, 2012
Aims. Star formation in massive galaxies is quenched at some point during hierarchical mass assembly. To understand where and when the quenching processes takes place, we study the evolution of the total star formation rate per unit total halo mass (Σ ...

Deciphering the Transcriptomic Signatures of Aging Across Organs in Mice

Aging Cell, Volume 25, Issue 2, February 2026.
Comprehensive transcriptomic profiling of eight mouse organs across six ages reveals how aging reshapes biological processes. Trajectory and network analyses distinguish shared and organ‐specific signatures, charting the molecular landscape of systemic aging.

The Truncated Lindley Distribution with Applications in Astrophysics

Galaxies, 2019
This paper reviews the Lindley distribution and then introduces the scale and the double truncation. The unknown parameters of the truncated Lindley distribution are evaluated with the maximum likelihood estimators.
