Jellyfish galaxies, characterised by long filaments of stripped interstellar medium extending from their disks, are prime laboratories to study the results of ram pressure  stripping and to explore the astrophysics of galaxies under extreme conditions. I will  present a series of recent results in this field made by the GASP (GAs Stripping  phenomena in galaxies with MUSE) team based on a multi-wavelength survey of ram pressure-stripped galaxies. Using a combination of radio and optical observations, we have explored how the non-thermal components of the interstellar medium, namely magnetic fields and cosmic rays, evolve under the influence of ram pressure. I will present a model that explains the origin of non-thermal radio continuum tails and how the tail magnetic field can regulate the interplay between the stripped interstellar medium and the surrounding intracluster medium. I will also show how we can use the stripped ionised plasma tails to probe the microphysics of the intracluster medium. Finally, I will discuss the ongoing research and our future goals. 

Breve CV del Dr. Alessandro Ignesti:

ha ottenuto un Ph.D. in Astrophisica nel 2021 all'Università di Bologna e all'INAF-Istituto di Radioastronomia con una tesi sul ruolo dell'ICM nell'evoluzione delle sorgenti radio in ammassi di galassie "rilassati" (“Interplay between relativistic and thermal plasma in relaxed galaxy clusters ” usotto la supervisione del Prof. M. Gitti e del Dr. G. Brunetti.). Successivamente si è trasferito all'INAF-Padova per un postdoc (2021-attuale posizione) per lavorare con la collaborazione GASP dove è responsabile degli studi radio ed X delle galassie "jellyfish". E' membro del LOFAR Survey Key Project - Cluster Working group e del SKAO Extragalactic continuum working group.
