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…
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…
Probing Direct Waves in Black Hole Ringdowns
Naritaka Oshita, Sizheng Ma, Yanbei Chen +1
Merger gravitational waves from binary black hole coalescence carry rich information about the underlying spacetime dynamics. We analyze merger waves from comparable-mass and extre…
Emergent Turbulence in Nonlinear Gravity
Sizheng Ma, Luis Lehner, Huan Yang +3
Gravity in nonlinear and dynamical regimes underpins spectacular astrophysical phenomena and observable consequences, from the early universe to black hole collisions. In these ext…
Black hole spectroscopy: from theory to experiment
Emanuele Berti, Vitor Cardoso, Gregorio Carullo +65
The "ringdown" radiation emitted by oscillating black holes has great scientific potential. By carefully predicting the frequencies and amplitudes of black hole quasinormal modes a…
Physics of Pair Producing Gaps in Black Hole Magnetospheres
Alexander Y. Chen, Yajie Yuan, Huan Yang
In some low-luminosity accreting supermassive black hole systems, the supply of plasma in the funnel region can be a problem. It is believed that a local region with unscreened ele…
