[astroseminar at Sapienza] Gravity theory webinar Mon, May 10th @noon: Alexandre Toubiana (APC Paris) - "Modeling gravitational waves from exotic compact objects"

[Paolo Pani]

Announcement of the next gravity-theory webinar:

*Alexandre Toubiana (APC Paris)** - "*Modeling gravitational waves from
exotic compact objects*"*
*Mon, May 10th @noon*

Abstract:

*In the standard astrophysical paradigm, the only compact objects (with
C>0.1) are black holes (BHs) and neutron stars (NSs). However, extensions
of General Relativity (GR) and/or of the Standard Model can give rise to
``exotic compact objects'' (ECOs), which mimic the gravitational behavior
of BHs and NSs to varying degrees. Thus, exotic compact objects can be
difficult to distinguish from BHs and NSs in the inspiral phase of the
binaries observed by gravitational-wave detectors, but significant
differences may be present in the merger and post-merger signal.In this
talk I will briefly review some models of ECOs and numerical simulations of
non-BH binaries. Based on these results, I will present a toy model aiming
to capture the main features of the full GW signal emitted by ECO binaries
and use it to assess the detectability of such exotic signals with current
and future detectors, and whether they can be distinguished from black hole
binaries.*
