Mapping the Perseus Galaxy Cluster with XRISM: Gas Kinematic Features and their Implications for Turbulence
In this paper, we present extended gas kinematic maps of the Perseus cluster by combining five new XRISM/Resolve pointings observed in 2025 with four Performance Verification datasets from 2024, totaling 745 ks net exposure. To date, Perseus remains the only cluster that has been extensively mapped out to ~0.7$r_{2500}$ by XRISM/Resolve, while simultaneously offering sufficient spatial resolution to resolve gaseous substructures driven by mergers and AGN feedback. Our observations cover multipl…

Analyse: Möglicher Asteroideneinschlag in den Mond ließe sich noch verhindern
Noch ist nicht auszuschließen, dass der Asteroid 2024 YR₄ in sieben Jahren in den Mond einschlägt, mit gefährlichen Folgen. Gegenwehr wäre jetzt noch möglich.

Champagne, chauffeur privé… Jordan Bardella encore retoqué sur ses frais de campagne aux Européennes
La justice a confirmé que le contribuable n’avait pas à rembourser une partie des dépenses de la tête de liste du Rassemblement national lors du scrutin de 2024. Plusieurs centaines de milliers d’euros de coûts « excessifs » ou « sans finalité électorale ».

CNN's Daniel Dale fact checks Trump & calls outright B.S. on his blatant lies about inflation being 'defeated'.
Groceries costs are sky high due to Trump's immigration crackdown & wild tariffs, with all-up consumer prices are up 3.0% since Sept 2024.

Quadratic Kernel for Cliques or Trees Vertex Deletion
We consider \textsc{Cliques or Trees Vertex Deletion}, which is a hybrid of two fundamental parameterized problems: \textsc{Cluster Vertex Deletion} and \textsc{Feedback Vertex Set}. In this problem, we are given an undirected graph $G$ and an integer $k$, and asked to find a vertex subset $X$ of size at most $k$ such that each connected component of $G-X$ is either a clique or a tree. Jacob et al. (ISAAC, 2024) provided a kernel of $O(k^5)$ vertices for this problem, which was recently improve…

Trump started the verbal war with Canada shortly after the 2024 election.
He invited Prime Minister Trudeau to dine with him at Mar-a-Lago on November 29.
Trump said then that Canada should be the fifty-first state and that Trudeau should be its governor. (Later, Trump switched to Gretzky.)
“I look forward to seeing the governor again soon so that we may continue our in depth talks on tariffs and trade,” Trump posted on social media.
To this, Trudeau responded:

The New Detroit-Windsor Bridge Can’t Repair the Damage Trump Has Done
The opening of the Gordie Howe bridge has been delayed. It’s an apt metaphor for where U.S.-Canada relations have gone under Trump 2.0.
