"Galaxy clusters in the LoTSS-DR3:
Catalogues and detection pipeline for diffuse radio emission" by Chiara Stuardi et al. including me
https://arxiv.org/pdf/2605.06400It presents the automated detection of diffuse radio emission in clusters observed in radio, using a Convolutional neural network (RADIO-UNET) trained on my #SimulatedUniverses !
Once in a while, a decent use of #AI to do something humans cannot do on this scale (as quickly).

"The Impact of the Magnetised Cosmic Web on Ultra High Energy Cosmic Ray Propagation" by Allegra Firinu, myself and Carmelo Evoli.
We investigated the role of realistic extragalactic magnetic fields in deflecting E>1e18eV cosmic rays, effectively creating "an horizon" beyond which particles cannot reach us, as they are trapped by magnetic fields.

"Cold gas formation triggered by active galactic nuclei jet
feedback in galaxy cluster cores" by Stefano Sotira (PhD student with me at University of Bologna), and others, https://arxiv.org/pdf/2601.14391, submitted.It presents a sophisticated analysis of the formation of cold clumps forming stars, as an effect of "positive" feedback by AGN jets. Simulations using the moving mesh code AREPO.

"Magnetic field spreading from stellar and galactic dynamos into the exterior" by A. Brandenburg, O. Ghosh, myself and A. Neronovhttps://arxiv.org/pdf/2512.17770
It is the direct numerical simulation, using the PENCIL code, of how magnetic fields produced by the mean-field dynamo in (very idealised) galaxies distribute over large distances (i.e. potentially into voids).

"The network analysis of the cosmic web as a tool to constrain
cosmology and cosmic magnetism"
by Anton Rudakovskyi, myself and M. Tsizh (@mtsizh )https://arxiv.org/pdf/2511.22573
It's the exploration, using new (many) cosmological simulations, if the presence of large-scale primordial magnetic fields, or variations in the initial cosmological parameters, can be detected using #ComplexNetwork analysis of the cosmic web.

"Simulated rotation measure sky from primordial magnetic fields" by S. Mtchedlidze, myself et al.https://arxiv.org/abs/2511.19508
discussing the little explored use of the **average** Faraday Rotation from background polarised radio sources as a tool to constrain large scale (primordial?) magnetic fields in between galaxies and filaments.

#paperday (sort of): here is the final accepted version of our
"On the interpretation of XRISM X-ray measurements of #turbulence in the intracluster medium: a comparison with cosmological simulations" by myself and G. Brunetti
https://arxiv.org/abs/2507.04727
I did an earlier thread here: https://mastodon.social/@franco_vazza/114816701059679474
The paper only have a useful appendix, which explains why homogenous kolmogorov turbulent models are useful, until they get too simplistic! #astrophysics #astronomy #science

"Can galactic magnetic fields diffuse into the voids?"
(answer: NO!)https://arxiv.org/abs/2510.26918 by O. Ghosh et al., (including me) on #astroph today .
It is a necessary rebuttal to a recent paper (https://arxiv.org/abs/2505.14774) who claimed the possible magnetisation of voids by propagating a dipole solution for the magnetic fields of galaxies, assuming cosmic voids are textbook "vacua"
Not good at all! -
