The NICER "Reverberation Machine": A Systematic Study of Time Lags in Black Hole X-Ray Binaries
Jingyi Wang, Erin Kara, Matteo Lucchini +12
We perform the first systematic search of all NICER archival observations of black hole (and candidate) low-mass X-ray binaries for signatures of reverberation. Reverberation lags…
Disk, Corona, Jet Connection in the Intermediate State of MAXI J1820+070 Revealed by NICER Spectral-Timing Analysis
Jingyi Wang, Guglielmo Mastroserio, Erin Kara +14
We analyze 5 epochs of NICER data of the black hole X-ray binary MAXI J1820+070 during the bright hard-to-soft state transition in its 2018 outburst with both reflection spectrosco…
Relativistic reflection and reverberation in GX 339-4 with NICER and NuSTAR
Jingyi Wang, Erin Kara, James Steiner +8
We analyze seven NICER and NuSTAR epochs of the black hole X-ray binary GX 339-4 in the hard state during its two most recent hard-only outbursts in 2017 and 2019. These observatio…
The 2017 Failed Outburst of GX 339-4: Relativistic X-ray Reflection near the Black Hole Revealed by NuSTAR and Swift Spectroscopy
Javier A. García, John A. Tomsick, Navin Sridhar +12
We report on the spectroscopic analysis of the black hole binary GX 339-4 during its recent 2017-2018 outburst, observed simultaneously by the Swift and NuSTAR observatories. Altho…
Testing the Kerr metric using X-ray reflection spectroscopy: spectral analysis of GX 339-4
Jingyi Wang, Askar B. Abdikamalov, Dimitry Ayzenberg +5
Signatures of X-ray reprocessing (reflection) out of an accretion disk are commonly observed in the high-energy spectrum of accreting black holes, and can be used to probe the stro…
