The stochastic signal detected by NANOGrav, PPTA, EPTA, and CPTA can be explained by
the scalar-induced gravitational waves. In order to determine the scalar-induced …

Recently released data from pulsar timing array (PTA) collaborations provide strong
evidence for a stochastic signal consistent with a gravitational-wave background, potentially …

We derive the hyperbolic orbit of binary black holes with electric and magnetic charges. In
the low-velocity and weak-field regime, by using the Newtonian method, we calculate the …

We consider accretion of charged test matter by rotating, magnetic black holes and discuss a
number of aspects in which the interaction of the angular momentum contained in the …

Extreme mass ratio inspirals (EMRIs) are excellent sources for space-based observatories to
explore the properties of black holes and test no-hair theorems. We consider EMRIs with a …

Black holes can be electromagnetically charged or carry vector charge from new
fundamental fields. Their response to small fluctuations is of paramount importance to study …

The recent stochastic signal observed jointly by NANOGrav, parkes pulsar timing array,
European pulsar timing array, and Chinese pulsar timing array can be accounted for by …

We derive the approximate “analytic-kludge” waveforms for the inspiral of a charged stellar-
mass compact object (CO) into a charged massive Kerr-Newman black hole. The …

We consider extreme mass ratio inspirals during which an electrically charged compact
object with mass mp and the charge to mass ratio q inspirals around a Schwarzschild black …

During the fourth observing run of the LIGO-Virgo-KAGRA detector network, the LIGO
Livingston observatory detected a coalescing compact binary, GW230529_181500, with …
