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…
Lense-Thirring precession in ULXs as a possible means to constrain the neutron star equation-of-state
M. J. Middleton, P. C. Fragile, M. Bachetti +11
The presence of neutron stars in at least three ultraluminous X-ray sources is now firmly established and offers an unambiguous view of super-critical accretion. All three systems…
