Massive black hole binaries (MBHBs) are expected to be the loudest gravitational wave (GW) sources in the milli-Hz window which will be probed by the future Laser Interferometer Space Antenna. MBHs are also known to radiate at large luminosities, opening the possibility of future multimessenger observations of MBHBs. I will describe the dynamics of MBHBs, their expected GW and electromagnetic...
Pulsar timing arrays (PTAs) are long-term monitoring campaigns of many millisecond pulsars (MSPs). Their key science goal is the detection and characterization of the few-nHz gravitational wave background (GWB) expected primarily from the mergers of supermassive black holes. These waves are random (stochastic), but the shared vantage point of the earth introduces hallmark correlations in the...
In $\sim 2034$ LISA will be able to detect the gravitational waves (GWs) from the coalescence of massive black hole binaries (MBHBs) in between $[10^5,10^7] \, \rm M_{\odot}$ solar mass up to $z\sim 10$. If the merger happens in a wet environment, copious amounts of radiation across the entire electromagnetic (EM) spectrum is expected to be produced by the accretion of the gas onto the...
While most stars orbit about the center of their host galaxy for their entire lifetime, a few of them are less fortunate. Two-body interactions can scatter an unlucky star towards the supermassive black hole at the center of the galaxy. This star will suffer a tidal disruption and the resulting stellar debris gets accreted into the black hole. These stellar tidal disruptions events are rare...
Neutrinos are the most elusive particles in the Universe, capable of travelling nearly unimpeded across it. Despite the vast amount of data collected, a long standing and unsolved issue is still the association of high-energy neutrinos with the astrophysical sources that originate them. Amongst the candidate sources of neutrinos there are blazars, a class of extragalactic sources powered by...
