Disk, Corona, Jet Connection in the Intermediate State of MAXI J1820+070 Revealed by NICER Spectral-Timing Analysis

no code implementations9 Mar 2021 Jingyi Wang, Guglielmo Mastroserio, Erin Kara, Javier García, Adam Ingram, Riley Connors, Michiel van der Klis, Thomas Dauser, James Steiner, Douglas Buisson, Jeroen Homan, Matteo Lucchini, Andrew Fabian, Joe Bright, Rob Fender, Edward Cackett, Ron Remillard

We find the corona expansion (as probed by reverberation) precedes a radio flare by ~5 days, which may suggest that the hard-to-soft transition is marked by the corona expanding vertically and launching a jet knot that propagates along the jet stream at relativistic velocities.

No Time for Dead Time: Timing analysis of bright black hole binaries with NuSTAR

The most obvious effect is a distortion of the white noise level in the power density spectrum (PDS) that cannot be modeled easily with the standard techniques due to the variable nature of the dead time.
