Is the Gravitational-Wave Ringdown a Probe of the Event Horizon?
- V. Cardoso, E. Franzin, P. Pani
- Physics, Medicine
- Physical review letters
- 23 February 2016
It is commonly believed that the ringdown signal from a binary coalescence provides a conclusive proof for the formation of an event horizon after the merger. This expectation is based on the… Expand
Testing the nature of dark compact objects: a status report
- V. Cardoso, P. Pani
- Physics
- 10 April 2019
Very compact objects probe extreme gravitational fields and may be the key to understand outstanding puzzles in fundamental physics. These include the nature of dark matter, the fate of spacetime… Expand
Testing general relativity with present and future astrophysical observations
- E. Berti, E. Barausse, +50 authors M. Zilhão
- Physics
- 28 January 2015
One century after its formulation, Einstein's general relativity (GR) has made remarkable predictions and turned out to be compatible with all experimental tests. Most of these tests probe the theory… Expand
Testing strong-field gravity with tidal Love numbers
- V. Cardoso, E. Franzin, A. Maselli, P. Pani, G. Raposo
- Physics
- 4 January 2017
The tidal Love numbers (TLNs) encode the deformability of a self-gravitating object immersed in a tidal environment and depend significantly both on the object's internal structure and on the… Expand
Black holes as particle detectors: evolution of superradiant instabilities
- R. Brito, V. Cardoso, P. Pani
- Physics
- 3 November 2014
Superradiant instabilities of spinning black holes can be used to impose strong constraints on ultralight bosons, thus turning black holes into effective particle detectors. However, very little is… Expand
Gravitational-wave signatures of exotic compact objects and of quantum corrections at the horizon scale
- V. Cardoso, Seth Hopper, C. F. Macedo, C. Palenzuela, P. Pani
- Physics
- 30 August 2016
Gravitational waves from binary coalescences provide one of the cleanest signatures of the nature of compact objects. It has been recently argued that the postmerger ringdown waveform of exotic… Expand
Equation-of-state-independent relations in neutron stars
- A. Maselli, V. Cardoso, V. Ferrari, L. Gualtieri, P. Pani
- Physics
- 7 April 2013
Neutron stars are extremely relativistic objects which abound in our universe and yet are poorly understood, due to the high uncertainty on how matter behaves in the extreme conditions which prevail… Expand
Tidal Love numbers of a slowly spinning neutron star
- P. Pani, L. Gualtieri, V. Ferrari
- Physics
- 7 September 2015
By extending our recent framework to describe the tidal deformations of a spinning compact object, we compute for the first time the tidal Love numbers of a spinning neutron star to linear order in… Expand
Perturbations of slowly rotating black holes: massive vector fields in the Kerr metric
- P. Pani, V. Cardoso, L. Gualtieri, E. Berti, A. Ishibashi
- Physics
- 4 September 2012
We discuss a general method to study linear perturbations of slowly rotating black holes which is valid for any perturbation field, and particularly advantageous when the field equations are not… Expand
Massive spin-2 fields on black hole spacetimes: Instability of the Schwarzschild and Kerr solutions and bounds on the graviton mass
- R. Brito, V. Cardoso, P. Pani
- Physics
- 24 April 2013
Massive bosonic fields of arbitrary spin are predicted by general extensions of the standard model. It has been recently shown that there exists a family of bimetric theories of gravity—including… Expand
