Bundesregierung verlängert Treuhandverwaltung von Rosneft Deutschland
Die Bundesregierung hat die Treuhandverwaltung der deutschen Tochterfirma des russischen Ölkonzerns Rosneft ein weiteres Mal verlängert. "Mit der Verlängerung behält die Bundesnetzagentur weiterhin die Kontrolle über Rosneft Deutschland und damit auch über den jeweiligen Anteil in den drei Raffinerien PCK Schwedt, Miro (Karlsruhe) und Bayernoil (Vohburg)", …

Ukraine-Liveblog: ++ Russland greift ukrainische Energieanlage an ++
Das russische Militär hat ukrainischen Angaben zufolge bei neuen Luftangriffen ein Wärmekraftwerk in der Region Kiew attackiert. Außenminister Wadephul betonte, Deutschland werde sich an Sicherheitsgarantien für die Ukraine beteiligen.

Ums Eck von #Karlsruhe:
"Es klingt unglaublich, fast wie ein Serienplot. In einem Kurort im Nordschwarzwald sind Schmierereien aufgetaucht, die auf ein Terrornetzwerk hindeuten. Das Erschreckende: Das Landesamt für Verfassungsschutz weiß von nichts."

Schmierereien in Bad Herrenalb: Die Welt zerstören als Ziel
In Bad Herrenalb sind Graffiti aufgetaucht, die auf satanistische oder rechtsextreme Netzwerke verweisen wie "no lives matter" und "Milikolosskrieg".

A New Framework to Detect Multi-Messenger Signals from Bright Sporadic Stochastic Gravitational Wave Background
The temporal dependence of the astrophysical stochastic gravitational-wave (GW) background (SGWB) in the hecto-hertz band brings a unique avenue to identify multi-messenger signals to these sources by using coincident detection in both GW and multi-band EM signals. We developed a new analysis pipeline, \textit{Multi-messenger Cross-Correlation} (MC$^2$) that can search for EM counterparts to the SGWB signal originating from both modeled and unmodeled sources by harnessing the nearly full-sky ga…

Modeling Gravitational Wave Bias from 3D Power Spectra of Spectroscopic Surveys
We present a framework for relating gravitational wave (GW) sources to the astrophysical properties of spectroscopic galaxy samples. We show how this can enable using clustering measurements of gravitational wave (GW) sources to infer the relationship between the GW sources and the astrophysical properties of their host galaxies. We accomplish this by creating mock GW catalogs from the spectroscopic Sloan Digital Sky Survey (SDSS) DR7 galaxy survey. We populate the GWs using a joint host-galaxy…

GPU accelerated MHD in the DISPATCH framework using directive-based programming
We present a GPU-accelerated implementation of a magnetohydrodynamic (MHD) solver using directive-based programming with OpenMP target offloading. The solver is integrated into the DISPATCH framework, which organises the computational domain into a collection of asynchronously updated patches. To reduce GPU kernel launch overhead, patches are grouped into "bunches" that are updated collectively. While porting the particular solver required a complete code refactoring, it yielded performance gai…

Probing neutrino emission at GeV energies from compact binary mergers detected during O1-O4a with the IceCube Neutrino Observatory
Compact binary mergers, detected in gravitational waves since 2015, are candidate sources for astrophysical neutrinos in the GeV regime from proton-proton and proton-neutron collisions. This contribution presents the results of the search for such a signal using mergers detected during the fourth observing run of the LIGO, Virgo, and KAGRA interferometers. We use the dense infill array at the center of the IceCube detector, IceCube-DeepCore, to select neutrino candidates in the 0.5-5 GeV energy…
