The three-dimensional shapes of the galaxy cluster intracluster medium in eRASS1 [PDF]
Astronomy & AstrophysicsAims. The three-dimensional shapes of clusters are important for understanding the astrophysics of the clusters and as a probe in cosmological studies. Methods. We estimate the most probable three-dimensional shape of galaxy clusters in the first eROSITA

Interface-Directed High Fluorescence Efficiency Two-Dimensional Molecular Crystals With Surface-Exposed Active Sites. [PDF]
Adv Sci (Weinh)Here, we designed the Me‐FBSe molecule and prepared a two‐dimensional molecular crystal via liquid‐liquid interface assembly. The crystal preserves the high photoluminescence quantum while simultaneously ensuring the high‐density surface exposure of active sites.

oMEGACat. VII. Tracing Interstellar and Intracluster Medium of ω Centauri Using Sodium Absorptions [PDF]
The Astrophysical JournalWe investigate the foreground interstellar medium along the line of sight and intracluster medium of ω Centauri ( ω Cen) by measuring the equivalent width of Na I D absorptions from MUSE observations. The large line-of-sight velocity difference between ω

Shock Acceleration in the Intracluster Medium: Implications of Micromirror Confinement
The Astrophysical JournalMerging galaxy clusters exhibit strong observational evidence for efficient particle acceleration in the intracluster medium (ICM), particularly in the form of synchrotron-emitting radio relics and halos. Cosmic-ray (CR) electrons are likely accelerated (

From observations to simulations: A neural-network approach to intracluster medium kinematics
Astronomy & AstrophysicsWe present a systematic comparison between XMM-Newton velocity maps of the Virgo, Centaurus, Ophiuchus, and A3266 clusters and synthetic velocity maps generated from the Illustris TNG-300 simulated clusters.

Gas motion in the intracluster medium of the Virgo cluster replica
Astronomy & AstrophysicsWithin the deep gravitational potential of galaxy clusters lies the intracluster medium (ICM). At the first order, it is considered to be at hydrostatic equilibrium within the potential well.

SDSS-C4 3028: the Nearest Blue Galaxy Cluster Devoid of an Intracluster Medium
The Open Journal of AstrophysicsSDSS-C4 3028 is a galaxy cluster at $z=0.061$, notable for its unusually high fraction of star-forming galaxies with 19 star-forming and 11 quiescent spectroscopically-confirmed member galaxies. From Subaru/HSC imaging, we derived a weak lensing mass of $

CHANDRA X-Ray Observations of A119: Cold Fronts and a Shock in an Evolved Off-axis Merger
The Astrophysical Journal, 2023 We present Chandra X-ray observations of the dynamically complex galaxy cluster A119 ( z = 0.044). A119 is host to two narrow-angle-tail (NAT) radio sources (0053-015 and 0053-016), whose tails are oriented parallel to each other, despite orthogonally ...
