Dynamics of a switchback-like magnetic deflection induced by a propagating coronal jet
Jade Touresse, Etienne Pariat, Clara Froment +1
Parker Solar Probe (PSP) revealed the ubiquity of switchbacks (SBs), sharp, localised magnetic deflections in the nascent solar wind, renewing interest in their origin. One propose…
Tidal Excitation of Relativistic Stars
Zhiqiang Miao, Junquan Su, Neev Khera +1
How a relativistic star responds to a time-dependent tide has lacked a first-principles counterpart of the Newtonian normal-mode expansion. In general relativity, the tidal field i…
From the Test-Mass Limit to Binary Black-Hole Waveforms in Higher-Derivative Gravity
Chaoyi Yang, Neev Khera, Dongjun Li +1
Many higher-derivative theories predict stronger deviations from General Relativity for lower-mass black holes, while their nonlinear field equations often prevent reliable simulat…
Gravitational Waves from Green's Function Decomposition for a Kerr black hole: I. Equatorial ISCO Plunge
Junquan Su, Neev Khera, Abhishek Chowdhuri +2
We present a decomposition of the Kerr Green's function in the time domain, motivated by the frequency-domain split previously studied in the Schwarzschild limit. We show that the…
Modified Teukolsky Formalism for Extreme Mass-Ratio Inspirals in Higher-Derivative Gravity
Chaoyi Yang, Neev Khera, Dongjun Li +1
In this work, we study a model problem involving a point particle spiraling into a non-rotating black hole in higher-derivative theories of gravity. In such theories, both the back…
A nonlinear voice from GW250114 ringdown
Yi-Fan Wang, Sizheng Ma, Neev Khera +2
Gravitational-wave astronomy, by detecting ripples in spacetime, has opened a new window to observe compact objects and probe theories of gravity in the nonlinear strong-field regi…
Decomposition of Schwarzschild Green's Function
Junquan Su, Neev Khera, Marc Casals +3
We present a formulation of the spherically decomposed Green's function for a Schwarzschild black hole, based on a decomposition into two components, and , based on thei…
