Semi-Analytic Solutions For Warped, Super-Eddington Accretion Disks with Outflows
Gabriel Wohlfarth, Matthew Middleton, Omer Blaes +1
The discovery of billion solar mass black holes at high redshift challenges any standard Eddington-limited growth model. Previous work has shown that an advective accretion disk ca…
Strongly Magnetized Super-Eddington Accretion: How Spin and Accretion Rate Regulate Energy Output and Mass Loss
Tom Man Kwan, Lixin Dai, Cheuk Kwan Kan +5
Strongly magnetized super-Eddington accretion flows power many important astrophysical systems, but how black hole parameters control their output is unclear. We present 32 general…
The nature of tilted supercritical accretion discs
P. Chris Fragile, Matthew J. Middleton, Brooks Brasseur +2
In this paper, we report on the first 3D general relativistic radiation magnetohydrodynamic simulations of large supercritical accretion discs that are tilted with respect to the b…
Angle-dependent hardening of the reprocessed spectra in ULXs powered by accretion onto neutron stars
Sricheta Karmakar, Alexander A. Mushtukov, Matthew Middleton
It is anticipated that mass accretion rates exceeding approximately in X-ray pulsars lead to radiation-driven outflows from super-critical accretion disc…
GR-RMHD Simulations of Super-Eddington Accretion Flows onto a Neutron Star with Dipole and Quadrupole Magnetic Fields
Akihiro Inoue, Ken Ohsuga, Hiroyuki R. Takahashi +2
Although ultraluminous X-ray pulsars (ULXPs) are believed to be powered by super-Eddington accretion onto a magnetized neutron star (NS), the detailed structures of the inflow-outf…
Drop in the hard pulsed fraction and a candidate cyclotron line in IGR J16320-4751 seen by NuSTAR
Arash Bodaghee, Alan J. -L. Chiu, John A. Tomsick +10
We report on a timing and spectral analysis of a 50-ks NuSTAR observation of IGR J16320-4751 (= AX J1631.9-4752); a high-mass X-ray binary hosting a slowly-rotating neutron star. I…
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…
Modeling the light curves of ultraluminous X-ray sources as precession
T. Dauser, M. Middleton, J. Wilms
We present a freely available xspec model for the modulations seen in the long-term light curves of multiple ultraluminous X-ray sources (ULXs). By incorporating the physics of mul…
