Recent focus of Philippov's research group has been on: (i) developing models of coherent radio emission produced during pair production lightnings and relativistic magnetic reconnection occurring in magnetospheres of neutron stars, in application to rotation-powered pulsars and Fast Radio Bursts; (ii) understanding mechanisms of producing electromagnetic flares in accretion flows around supermassive black holes and magnetospheres of merging neutron stars and magnetars; (iii) exploring the role of kinetic plasma effects in shaping the dynamics and observational appearance of accreting plasmas around black holes in M87 and Milky Way; (iv) investigating electron and proton acceleration in radiative plasma turbulence occurring in the magnetized coronae of black holes. These ongoing efforts contribute to interpreting the observed signatures of black holes and neutron stars using first-principles physics.
