One of the longest-standing science targets of gravitational-wave detectors are spinning deformed neutron stars. While exceedingly weak and hence still eluding detection, "continuous waves" from such individual objects will bring a new regime of gravitational astrophysics where we can keep observing the same source over and over and perform rich multi-messenger studies. They promise an...
Neutron stars are expected to produce continuous gravitational waves arising due to precession and, crucially, deformations in the crust, also called mountains. The microscopical resistance to breaking used in ellipticity calculations is obtained from Molecular Dynamics simulations. In this talk I will show our results from our simulations, that incorporate finite size and magnetic fields. I...
While standard analyses of black-hole mergers assume these happen in vacuum, it is expected that these will happen in dense environments. This is particularly true for mergers involving component black holes populating the so-called pair-instability supernova gap, which should form hierarchically as the result of a previous merger in an environment dense enough to retain the remnant black...
Black holes and neutron stars are the leading candidates for the sources of currently observed gravitational waves. However, exotic compact objects have been proposed as potential alternatives, capable of mimicking the gravitational-wave signatures of these standard sources. Among them, Proca stars—Bose-Einstein condensates of complex vector ultralight bosons—have attracted...
Binary supermassive black holes are expected to form and merge at galactic centers. Their dynamics encode information on their formation and environments, and can be observed by low frequency gravitational-wave detectors, potentially offering a multi-messenger source. Despite this interest, no close-by (sub parsec) binaries have been confidently identified yet.
I will describe a new method...
