Role of Anharmonicity and Bimetallic Intermixing in the IR and Raman Spectra of Cun$_{n}$ and Pdn$_{n}$Cu6−n$_{6-n}$ Clusters (n<7$n\lt 7$). Ab Initio Benchmarking of DFT

Small Structures, Volume 7, Issue 5, May 2026.
High‐level ab initio and density functional theory calculations reveal a structural and spectroscopic transition from pla nar Cu6 to three‐dimensional Pd6, whose lowest energy triplet state undergoes a Jahn‐Teller distortion. This evolution from molecule‐like to metal‐like bonding produces distinct infrared and Raman fingerprints, providing reliable ...

Generation of internal waves by buoyant bubbles in galaxy clusters and heating of intracluster medium [PDF]

, 2018
Buoyant bubbles of relativistic plasma in cluster cores plausibly play a key role in conveying the energy from a supermassive black hole to the intracluster medium (ICM) - the process known as radio-mode AGN feedback.

Surface Brightness Fluctuations in Two SPT Clusters: A Pilot Study

The Astrophysical Journal
Studies of surface brightness fluctuations in the intracluster medium present an indirect probe of turbulent properties such as the turbulent velocities, injection scales, and the slope of the power spectrum of fluctuations toward smaller scales.

Deep Synoptic Array Science: Two Fast Radio Burst Sources in Massive Galaxy Clusters

The Astrophysical Journal Letters, 2023
The hot gas that constitutes the intracluster medium (ICM) has been studied at X-ray and millimeter/submillimeter wavelengths (Sunyaev–Zel’dovich effect) for decades.

Enrichment of the Intracluster Medium [PDF]

, 1999
The relevance of galaxies of different luminosity and mass for the chemical enrichment of the intracluster medium (ICM) is analysed. For this purpose, I adopt the composite luminosity function of cluster galaxies from Trentham (1998), which exhibits a significant rise at the very faint end.

INTRACLUSTER MEDIUM OF THE MERGING CLUSTER A3395 [PDF]

The Astrophysical Journal, 2011
We present a detailed imaging and spectral analysis of the merging environment of the bimodal cluster A3395 using X-ray and radio observations. X-ray images of the cluster show five main constituents of diffuse emission : A3395 NE, A3395 SW, A3395 NW, A3395 W, and a filament connecting NE to W.

Suppression of AGN-driven Turbulence by Magnetic Fields in a Magnetohydrodynamic Model of the Intracluster Medium [PDF]

, 2018
We investigate the role of active galactic nucleus (AGN) feedback in turbulent heating of galaxy clusters. Specifically, we analyze the production of turbulence by g-modes generated by the supersonic expansion and buoyant rise of AGN-driven bubbles ...

Propagation of cosmic rays and their secondaries in the intracluster medium

, 2021
We present results of the propagation of high-energy cosmic rays (CRs) and their secondaries in the intracluster medium (ICM). To this end, we employ three-dimensional cosmological magnetohydrodynamical simulations of the turbulent intergalactic medium ...

IDLB: An SDN‐Based Load‐Balancing Routing Protocol for Autonomous Satellite Constellation Networks

International Journal of Satellite Communications and Networking, Volume 44, Issue 2, Page 109-127, March/April 2026.
ABSTRACT Routing in satellite constellation networks with intersatellite links has become an important aspect to enable broadband Internet access and to integrate into terrestrial networks. However, their dynamic characteristics and large physical size require specifically tailored solutions.
