Test of Cosmic Web-feeding Model for Star Formation in Galaxy Clusters in the COSMOS Field

The Astrophysical Journal
It is yet to be understood how large-scale environments influence star formation activity in galaxy clusters. One recently proposed mechanism is that galaxy clusters can remain star forming when fed by infalling groups and star-forming galaxies from ...

The SRG/eROSITA All-Sky Survey

Astronomy & Astrophysics
We selected galaxy cluster candidates from the high-redshift (BEST_Z > 0.9) end of the first SRG (Spectrum Roentgen Gamma)/eROSITA All-Sky Survey (eRASS1) galaxy cluster catalogue, for which we obtained moderately deep J-band imaging data with the ...

The effect of simulated intergroup encounters on movement patterns and home range use in banded mongooses

Wildlife Biology, EarlyView.
Intergroup conflicts have a wide range of impacts, including affecting movement and ranging patterns. Previous studies found contrasting movement responses to intergroup conflicts, but no explanation for these differences has been suggested. However, these can be broadly grouped into ‘conflict avoidance' responses: avoiding areas close to the fight ...

Genotyping Contemporary Captive and Historical Wild Western Lowland Gorillas Indicates Captive Breeding Is Maintaining Genetic Diversity in a Critically Endangered Primate

Animal Conservation, EarlyView.
Captive populations of threatened species risk losing genetic diversity over time. We evaluated the genetic status of contemporary captive western lowland gorillas (Gorilla gorilla gorilla) at Howletts and Port Lympne and compared this with specimens from a historical wild population.

The JWST Discovery of the Triply Imaged Type Ia “Supernova H0pe” and Observations of the Galaxy Cluster PLCK G165.7+67.0

The Astrophysical Journal
A Type Ia supernova (SN) at z = 1.78 was discovered in James Webb Space Telescope Near Infrared Camera imaging of the galaxy cluster PLCK G165.7+67.0 (G165; z = 0.35).

A New Algorithm for the Detection of Inter-cluster Galaxy Filaments using Galaxy Orientation Alignments

, 2005
We present a new algorithm to detect inter-cluster galaxy filaments based upon the assumption that the orientations of constituent galaxies along such filaments are non-isotropic.

Toll‐like receptor 4 mediates lipopolysaccharide‐induced emesis

British Journal of Pharmacology, EarlyView.
Background and Purpose Lipopolysaccharide (LPS) induces inflammation and sepsis through Toll‐like receptor 4 (TLR4) activation. Common laboratory animals do not exhibit emesis, but administration of LPS in piglets, cats, and dogs induces emesis via peripheral mechanisms.

Stellar Populations and Radial Migrations in Virgo Disk Galaxies

, 2012
We present stellar age profiles for 64 Virgo cluster disk galaxies whose analysis poses a challenge for current galaxy formation models. Our results can be summarized as follows: first, and contrary to observations of field galaxies, these cluster ...
