Intrinsic Mass–Richness Relation of Clusters from THE THREE HUNDRED Hydrodynamic Simulations

The Astrophysical Journal
The main systematics in cluster cosmology is the uncertainty in the mass–observable relation. In this paper, we focus on the most direct cluster observable in optical surveys, i.e., richness, and constrain the intrinsic mass–richness (MR) relation of ...

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.

Efficiency of Turbulent Reacceleration by Solenoidal Turbulence and Its Application to the Origin of Radio Megahalos in Cluster Outskirts

The Astrophysical Journal
Recent radio observations with the Low Frequency Array (LOFAR) discovered diffuse emission extending beyond the scale of classical radio halos. The presence of such megahalos indicates that the amplification of the magnetic field and acceleration of ...

Identification of key gut microbiota and microbial QTL in contributing to the significant differences in body weight between two Chinese local chicken breeds

Animal Genetics, Volume 57, Issue 1, February 2026.
Abstract Previous studies have identified genetic loci that are associated with both feed conversion efficiency and gut microbiota in chickens, suggesting that interactions between the host genome and gut microbiota may influence chicken growth. However, the number of microbial QTL and gut microbiota associated with chicken body weight remains largely ...

Estimating Cluster Masses: A Comparative Study between Machine Learning and Maximum Likelihood

The Astrophysical Journal
We compare an autoencoder convolutional neural network (AE-CNN) with conventional maximum-likelihood estimation (MLE) for inferring cluster virial masses, M _v , directly from the galaxy distribution around clusters, without identifying members or ...
