Aretakis Hair for Extreme Kerr Black Holes with Axisymmetric Scalar Perturbations
Lior M. Burko, Gaurav Khanna, Subir Sabharwal
We study the evolution of axially-symmetric scalar field perturbations on an extreme Kerr spacetime for initial data with multipole moments higher than the least ra…
New Horizons for Fundamental Physics with LISA
K. G. Arun, Enis Belgacem, Robert Benkel +138
The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders about the fundamental theory of nature at play in the extreme gravity regime, where the gravitatio…
Climbing up the memory staircase: Equatorial zoom-whirl orbits
Lior M. Burko, Gaurav Khanna
The nonlinear, or null gravitational memory effect for zoom-whirl orbits around fast spinning Kerr black holes for extreme mass ratio systems has a staircase structure. The latter…
Scalar and gravitational hair for extreme Kerr black holes
Lior M. Burko, Gaurav Khanna, Subir Sabharwal
For scalar perturbations of an extreme Reissner-Nordstr{\" o}m black hole we show numerically that the Ori pre-factor equals the Aretakis conserved charge. We demonstrate a linear…
Repeated Ringing of the Black Hole's Bell: Quasi-Normal Bursts from Highly Eccentric, Extreme Mass-Ratio Binaries
Nur E. M. Rifat, Gaurav Khanna, Lior M. Burko
Recent studies of scalar and gravitational waveforms from high-eccentricity, extreme mass-ratio black hole binaries show the presence of quasi-normal bursts (QNB) -- lingering high…
(Transient) Scalar Hair for (Nearly) Extreme Black Holes
Lior M. Burko, Gaurav Khanna, Subir Sabharwal
It has been shown recently that extreme Reissner-Nordström black holes perturbed by a minimally coupled, free, massless scalar field have permanent scalar hair. The hair - a conser…
