Extreme-Mass-Ratio Inspirals in Gaseous Disks
Alexander J. Dittmann, Abhishek Hegade K. R., Callum W. Fairbairn
Gravitational waves from extreme mass ratio inspirals (EMRIs) are precise probes of the environment of the supermassive black holes (SMBHs) they orbit. If an SMBH is actively accre…
A New Spin on Dissipative Tides: First-Post-Newtonian Effects in Compact Binary Inspirals
Anand Balivada, Abhishek Hegade K. R., Nicolás Yunes
Tidal dissipation in spinning compact binaries imprints characteristic corrections on the late-inspiral gravitational-wave signal. We develop a next-to-leading order post-Newtonian…
Universal Relations with Dynamical Tides
Jayana A. Saes, Abhishek Hegade K. R., Nicolás Yunes
Observations of neutron stars and the precise measurement of their macroscopic properties have provided valuable insights into fundamental physics, both by constraining the behavio…
The Good, the Bad, and the Subtle: Relativistic mode sums for neutron-star tidal response
Abhishek Hegade K. R., K. J. Kwon, Tejaswi Venumadhav +2
Time-dependent tidal interactions during the late inspiral of binary neutron stars encode valuable information about neutron-star structure, but systematically extending the famili…
Kinetic magnetohydrodynamics and Landau fluid closure in relativity
Abhishek Hegade K. R., James M. Stone
Diffuse accretion flows near a supermassive black hole are fundamentally weakly collisional. In such weakly collisional plasmas, the ion and electron distribution functions can dev…
Relativistic and Dynamical Love
Abhishek Hegade K. R., K. J. Kwon, Tejaswi Venumadhav +2
Gravitational waves emitted in the late inspiral of binary neutron stars are affected by their tidal deformation. We study the tidal dynamics in full general relativity through mat…
