**Goal**: investigate the idea of relieving the Hubble tension with primordial magnetic fields, generalize and make forecasts

**Tools**: MCMC/nested sampling with Cobaya using CLASS Boltzmann code

**Open source**: modified CLASS with clumping models.

(Dr. Omer Bromberg, Prof. Alexander Tchekhovskoy)

**Goal**: study their launching, propagation, instabilities, energy dissipation

**Tools**: GRMHD simulations in H-AMR code (improved version of HARM and harmpi)

**My contribution**: implementing the rotating perfect conductor BC, matter injection, grid modifications, tilting the jet to avoid pole singularity issues

**Open source**: harmpi with the neutron star boundary condition.

(Prof. Vasily Beskin, Dr. Alexander Philippov)

**Goal**: understanding the reason of discrepancy between numerical simulations and theoretical considerations - the first give that total energy loss rate increases with inclination angle (between magnetic dipole and rotation axis), while the second gave the opposite trend

**Key results**: additional separatrix currents are important factor of radiopulsar losses reproduced in simulations; most of the energy starts flowing along open magnetic field lines already within the light cylinder; losses in numerical simulations are not dipolar

**My contribution**: analysis of electromagnetic field configuration in a force-free simulation snapshot; a method to separate polar cap from closed field lines region

**Publication**: Beskin, V. S., A. K. Galishnikova, E. M. Novoselov, A. A. Philippov, and **M. M. Rashkovetskyi**, 2017. So how do radio pulsars slow-down?. Journal of Physics Conference Series 932, 012012.

(Prof. Vasily Beskin, Egor Novoselov, Alisa Galishnikova, Dr. Anton Biryukov)

**Goal**: test two key models of radiopulsar period and inclination angle evolution (one theoretical by Beskin, Gurevich and Istomin (BGI) with one based on MHD and force-free simulations by Spitkovsky, Tchekhovskoy, Philippov and others) by predicting seen orthogonal pulsar numbers and comparing them to observed ones

**My contribution**: sampling pulsar distribution functions with Monte-Carlo simulation, making predictions based on it

**Publication**: Novoselov, E. M., V. S. Beskin, A. K. Galishnikova, **M. M. Rashkovetskyi**, and A. V. Biryukov, 2020. Orthogonal pulsars as a key test for pulsar evolution. Monthly Notices of the Royal Astronomical Society 494, 3899-3911.

**Open source**: pulsar distribution sampling code.

(Prof. Vasily Beskin, Dr. Alexander Philippov)

**Goal**: understand the morphology of pulsar light-curves; find observational evidence of separatrix currents

**Method**: ray-tracing and integrating the polarization parameters according to Kravtsov-Orlov equation
