ALP searches on Mrk 421 & BL Lac

• PI: Ivana Batkovic [29]. Team: Giacomo D'Amico, Michele Doro, Marina Manganaro, Sami Caroff, Pooja Bhattacharjee, Francesca Calore and David Sanchez . Contact us if interested
• Abstract: Axion Like Particles can be detected as wiggles in the spectra of faraway targets whose high energy emission crossed intense and ample region of magnetic fields. Such targets are the high energy emission from galaxies in Galaxy Cluster's core or those emitted within relativistic jets. Here we focus on the second class, and in particular on Mrk421 jet. The investigation relies on the modelization of the B-field in the ultrarelativistic jet.
