Where within the 3C 84 jet are -rays produced?

Georgios F. Paraschos, Ioannis Liodakis, Svetlana Jorstad +49

The location of -ray creation and emission within extra-galactic jets is a matter of active debate. One particularly well-suited source to pinpoint the location is the nearby,…

Disentangling Multiple Gas Kinematic Drivers in the Perseus Galaxy Cluster

XRISM Collaboration, Marc Audard, Hisamitsu Awaki +143

Galaxy clusters, the Universe's largest halo structures, are filled with 10-100 million degree X-ray-emitting gas. Their evolution is shaped by energetic processes such as feedback…

Detection of Compton scattering in the jet of 3C 84

Ioannis Liodakis, Sudip Chakraborty, Frédéric Marin +77

3C 84 is the brightest cluster galaxy in the Perseus Cluster. It is among the closest radio-loud active galaxies and among the very few that can be detected from low frequency radi…

A Yin-Yang Galaxy Cluster Merger in Abell 1914 Revealed by XRISM

Annie Heinrich, Congyao Zhang, Irina Zhuravleva +4

Hierarchical mergers of galaxy clusters play a key role in converting gravitational energy into thermal and kinetic energy in the local universe. Understanding this process require…

The bulk motion of gas in the core of the Centaurus galaxy cluster

XRISM collaboration

Galaxy clusters, the largest gravitationally bound structures in the Universe, contain vast amounts of dark matter, galaxies, and hot ionised gas known as the intracluster medium (…

Decoding AGN Feedback with X-arithmetic: From Morphology to Physical Mechanisms

Hannah McCall, Irina Zhuravleva, Eugene Churazov +4

Feedback from Active Galactic Nuclei (AGN) is a key process in the evolution of massive halos in the Universe. New observational information on feedback is crucial for improving th…
