#paperday on #astroph:
another chapter contribution to the Advancing Astrophysics with the SKAII big collection of papers trying to outline what the SKA may and should be doing in a few years 🤞🏼

In this one I helped giving a sense of what might be detectable with a few different survey configurations for SKA-LOW and MID, on the scale of filaments of the cosmic web:

SKA lenses" by Cuciti et al.

"An SKA-Low RM Grid for constraining the origin of cosmic magnetism" by S. O'Sullivan, myself and others

https://arxiv.org/abs/2606.25096

in one of the many contribution to the Advancing Astrophysics with the SKA II collection of works.

Here we discuss the many directions in which the SKA is going to improve our understanding of cosmic magnetism using its polarisation capabilities, to study the Faraday Rotation effect across the cosmic web

"Isochrones in primordial magnetic field evolution"
by A. Brandenburg, Cielo, Iarygina & myself
https://arxiv.org/pdf/2606.10863

where we present Pencil simulations of the evolution of different stochastic magnetic field configurations in the early universe, with the goal of finding simple ways to rescale them to the same evolutionary sequence.

"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/2605.06400

It 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.

"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.
