A Generative Model for Realistic Galaxy Cluster X-Ray Morphologies

The Astrophysical Journal
The X-ray morphologies of clusters of galaxies display significant variations, reflecting their dynamical histories and the nonlinear dependence of X-ray emissivity on the density of the intracluster gas. Qualitative and quantitative assessments of X-ray

Substrate‐Affinitive P‐Type Azapolycyclic Photosensitizer for Chemoselective Nitrilization Under Mild Conditions

Advanced Science, Volume 13, Issue 36, 29 June 2026.
We developed a series of quinoxalinoquinoxaline (QQ) photosensitizers featuring high and tunable excited‐state reduction potentials (E(PC•+/PC*) = –1.76 to –2.05 V vs. SCE). Their hydrogen‐bonding interaction with carbonyl substrates enables selective single‐electron transfer events for selective nitrilization of 1° amides, offering a tunable ...

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.

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.

Sustainable Livestock Decisions in a Post‐Conflict Frontier: Evidence From Colombia's Orinoquía

Journal of Agricultural Economics, Volume 77, Issue 2, Page 304-319, June 2026.
ABSTRACT The Orinoquía region is one of Colombia's principal agricultural frontiers and has been shaped by long‐standing armed‐conflict dynamics that continue to influence land governance, producer incentives, and investment decisions. Efforts to promote sustainable cattle production emphasize two key practices: sustainable pasture management ...

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.

Machine Learning–Driven Insights Into the Self‐Assembly of Gold–Thiolate Nanoclusters

Aggregate, Volume 7, Issue 5, May 2026.
A machine‐learned atomistic potential, trained by data from density‐functional theory calculations on thiolate‐protected gold nanoclusters, is applied to investigate cluster–cluster reactions in 0.1 µs timescale molecular dynamics simulations. Starting from a few experimentally known cluster stoichiometries and structures, the simulations show a ...

Sound waves in the intracluster medium [PDF]

Monthly Notices of the Royal Astronomical Society, 2009
We present an analysis of the behaviour of a perturbed radio cocoon. Comparisons with observations of sound waves detected in the Perseus and Virgo clusters suggest the separations of observed ripples correspond to the natural oscillation frequency of the cocoon.

Histidine Protonation and the Oxidizing Power of the Oxygen‐Evolving Complex

ChemPhotoChem, Volume 10, Issue 5, May 2026.
Protonation of D1‐His337 governs the oxidizing power of the Mn4CaO5 cluster in photosystem II. Its singly protonated form is unstable, resulting in histidine oxidation and disruption of Mn oxidation, whereas the doubly protonated form is stable and upshifts the cluster redox potential, enabling efficient water oxidation.
