Restrictions on Extended Gravity at Galaxy Clusters Scales

EPJ Web of Conferences, 2018
Following [1] we discuss the predictions of Starobinsky model of f(R)-gravity with vanishing cosmological constant at galaxy and galaxy clusters scales.

A spectroscopic census of the M82 stellar cluster population

, 2009
We present a spectroscopic study of the stellar cluster population of M82, the archetype starburst galaxy, based primarily on new Gemini-North multi-object spectroscopy of 49 star clusters.

Gut Mycobiota of Three Rhinopithecus Species Provide New Insights Into the Association Between Diet and Environment

Integrative Zoology, EarlyView.
This study revealed the basic structures of gut mycobiota of three wild Rhinopithecus species. The gut mycobiota of Rhinopithecus showed close connection with their feeding habits, and there were associations between gut mycobiota and the host's living environments.

Multiobject Spectroscopy of Galaxy Clusters at z ∼ 0.95 in the Ultra Deep Survey Field with Different Star Formation Properties and Large-scale Environments

The Astrophysical Journal Supplement Series
While galaxy clusters are dominated by quiescent galaxies in the local Universe, they show a wide range in quiescent galaxy fraction (QF) at higher redshifts.

Taxon‐specific BLAST percent identity thresholds for identification of unknown sequences using metabarcoding

Methods in Ecology and Evolution, EarlyView.
Abstract The identification of organisms in environmental samples using metabarcoding relies on factors such as taxonomic assignment methods, genetic markers, reference databases and confidence thresholds for taxonomic assignment. Because lineages evolve at different rates, a global threshold (e.g.

Quantifying the Velocity Anisotropy Profile of Galaxy Clusters Using the Uchuu Cosmological Simulation

The Astrophysical Journal
Galaxy clusters are powerful laboratories for studying both cosmic structure formation and galaxy evolution. We present a comprehensive analysis of the velocity anisotropy profile, β ( r ), in galaxy clusters using the Uchuu-UniverseMachine mock galaxy ...

Cell‐Surface LAMP1 is a Senescence Marker in Aging and Idiopathic Pulmonary Fibrosis

Aging Cell, EarlyView.
We have validated the selective upregulation of LAMP1 in SEN in culture, and the percentage of Lamp1+ cells increases in various tissues with age, as well as in fibrotic lungs following BLM instillation. The RNA‐Sequencing analysis of the Lamp1‐enriched populations confirmed the enrichment of senescence‐related genes.

Distribution of Merging and Post-merger Galaxies in Nearby Galaxy Clusters

The Astrophysical Journal
We study the incidence and spatial distribution of galaxies that are currently undergoing gravitational merging (M) or that have signs of being post-merger (PM) in six galaxy clusters (A754, A2399, A2670, A3558, A3562, and A3716) within the redshift ...
