Persistence of the Millihertz X-ray Quasi-Periodic Oscillation in the Active Galactic Nucleus 1ES 1927+654
Megan Masterson, Erin Kara, William N. Alston +15
1ES 1927+654 is an extreme active galactic nucleus (AGN) that has defied our canonical expectations for how AGN appear across the electromagnetic spectrum and how they vary on shor…
Tilted, warped, and eccentric disks
P. Chris Fragile, Adam Ingram, Gibwa Musoke +1
We review some of the interesting consequences that tilts, warps, and eccentricities can introduce into the dynamics, thermodynamics, and observational appearance of accreting syst…
Characterizing the Broadband Reflection Spectrum of MAXI J1803-298 During its 2021 Outburst with NuSTAR and NICER
Oluwashina Adegoke, Javier Garcia, Riley Connors +12
MAXI J1803-298 is a transient black hole candidate discovered in May of 2021 during an outburst that lasted several months. Multiple X-ray observations reveal recurring "dipping" i…
Magnetospheric Flows in X-ray Pulsars I: Instability at super-Eddington regime of accretion
A. A. Mushtukov, A. Ingram, V. F. Suleimanov +5
Within the magnetospheric radius, the geometry of accretion flow in X-ray pulsars is shaped by a strong magnetic field of a neutron star. Starting at the magnetospheric radius, acc…
Variability as a predictor for the hard-to-soft state transition in GX 339-4
Matteo Lucchini, Marina Ten Have, Jingyi Wang +17
During the outbursts of black hole X-ray binaries (BHXRBs), their accretion flows transition through several states. The source luminosity rises in the hard state, dominated by non…
Modelling hard and soft state of Cygnus X-1 with propagating mass accretion rate fluctuations
S. Rapisarda, A. Ingram, M. van der Klis
We present a timing analysis of threeRossi X-ray Timing Explorer observations of the black hole binary Cygnus X-1 with the propagating mass accretion rate fluctuations model PROPFL…
