Hierarchical constraints on gravitational waves from horizonless compact objects
Rajrupa Mondal, Julian Westerweck, Yotam Sherf +2
We use the data of several promising gravitational wave observations to obtain increasingly stringent bounds on near-horizon deviations of their sources from the Kerr geometry. A r…
Discovering Love numbers through resonance excitation during extreme mass ratio inspirals
Shani Avitan, Ram Brustein, Yotam Sherf
General Relativity predicts that black holes do not possess an internal structure and consequently cannot be excited. This leads to a specific prediction about the waveform of grav…
Sub-atomic constraints on the Kerr geometry of GW150914
Julian Westerweck, Yotam Sherf, Collin D. Capano +1
We obtain stringent constraints on near-horizon deviations of a black hole from the Kerr geometry by performing a long-duration Bayesian analysis of the gravitational-wave data imm…
Classical Love for Quantum Blackholes
Ram Brustein, Yotam Sherf
We present a method for comparing the classical and quantum calculations of the electric quadrupolar Love number and show that our previous derivation of the quantum Love num…
Tidal-heating/viscous dissipation correspondence in black holes and viscous compact objects
Yotam Sherf
The effect of energy absorption during the binary evolution of Exotic-compact-objects (ECOs) is extensively studied. We review the underlying mechanism that provides the energy dis…
Quantum Love
Ram Brustein, Yotam Sherf
The response of a gravitating object to an external tidal field is encoded in its Love numbers, which identically vanish for classical blackholes (BHs). Here we show, using standar…
Hyperbolicity Constraints in Extended Gravity Theories
Yotam Sherf
We study the characteristic structure of the Einstein-Hilbert (EH) action when modifications of the form of , and are included. We show th…
