The cascade of kinetic and magnetic energy from large to small scales in galactic-style turbulence behaves significantly different to the theoretical models that we usually assume work. nature.com/articles/s4155… Published in Nature Astronomy.

If there’s any #astrotwitter folks left here check out two new papers on arxiv today description the #ASKAP #EMU survey arxiv.org/abs/2505.08271 and the #POSSUM survey arxiv.org/abs/2505.08272

Thin filaments in the tails of A2255, by Emanuele De Rubeis+ (w/ myself++) A2255 is known to be a "mess" (arxiv.org/abs/2006.04808). The new Low Frequency Array-VLBI images add further complexity in the system, this time revealing small-scale structures in its radio galaxies arxiv.org/abs/2505.13595

The central region of A3667 in hard X-rays, by Mohammad Mirakhor+Stephen A Walker A NASA NuSTAR mission observation of the cluster is presented. The spectrum is better described by a 2T thermal model. An updated limit of B > 0.2 muG is provided from the lack of IC emission arxiv.org/abs/2505.20453

📢Paper and press releases day! We report the first-ever unambiguous detection of WHIM/missing baryons in a single cosmic filament using ESA XMM-Newton and JAXA(Japan Aerospace Exploration Agency) Suzaku data! It's the first time observations agree with LCDM simulations for the nature of WHIM aanda.org/component/cont…

MeerKAT observations of CHEX-MATE clusters, by Balboni+ (w/ Fabio Gastaldello, Rossella Cassano, Giacomo Riva, Max Gaspari, Mariachiara Rossetti, myself++) A sample of 21 massive clusters is studied. Diffuse radio emission is detected in all systems (new halos and relics!) arxiv.org/abs/2507.00133

The magnetic field in A2142, by Pagliotta+ (w/ Chiara Stuardi, FraLoi++) A rotation measure and polarization study is performed with MeerKAT. The magnetic field profile of the ICM is drawn, indicating a central field strength of 9.5 muG at the cluster center. arxiv.org/abs/2507.00114

.XRISM obs of the Ophiuchus cluster, by Fujita+ A low velocity dispersion is measured in the inner and outer regions (115 km/s at <25kpc, 186 km/s at 25-50 kpc). The same goes for the bulk velocity (8 km/s vs 104 km/s): is the sloshing at its minimum? arxiv.org/abs/2507.00126
