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.<br>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.</i><br><br>Zoom link: <a href="https://uniroma1.zoom.us/j/81283707469?pwd=SzkyMk5jRm0xcEN3WE5MYVh1RVFtQT09" target="_blank">https://uniroma1.zoom.us/j/81283707469?pwd=SzkyMk5jRm0xcEN3WE5MYVh1RVFtQT09</a><br>ID meeting: 812 8370 7469<br>Passcode: 915450</div><div><br></div><div>Have a nice weekend,</div><div>Paolo</div><br>-- <br>Paolo Pani <br>Associate Professor<br>ERC StG Fellow, DarkGRA project<br>Junior Fellow, Scuola Superiore di Studi Avanzati Sapienza<br><br>Physics Department (Marconi Building), 3rd floor, room 334<br>Sapienza University of Rome<br>Piazzale Aldo Moro 5 - 00185 Rome (Italy) <br>+39 06 4991 4472 (int 24472)</div>
