Multiple mountains on a pulsar: implications for gravitational waves and the spin-down rate
Paritosh Verma, Sudip Bhattacharyya
A pulsar, i.e., a spinning neutron star, with a deformation could emit gravitational waves continuously. Such continuous waves, which have not been detected yet, will be very usefu…

Influence of dark photon on magnetized and charged particle orbits around static spherically symmetric black hole
Marek Rogatko, Paritosh Verma
We elaborate the problem of magnetized particle motion in the spacetime of a static, spherically symmetric black hole influenced by weak magnetic fields stemming from visible and d…

Can synchrotron radiation reveal the presence of {\it dark sector} around black hole?
Marek Rogatko, Paritosh Verma
We studied synchrotron radiation of a massive charged under visible and hidden sector groups, moving in equatorial plane around spherically symmetric weakly magnetized black hole.…
