XFit: Global Optimization and Degeneracy Mapping in X-ray Spectral Modeling
Austin MacMaster, Adam Rogers, Jason Fiege +2
The standard approach to modeling X-ray spectral data relies on local optimization methods, such as the Levenberg-Marquardt algorithm. While effective for simple models and speedy…
The Advanced X-ray Imaging Satellite (AXIS) Community Science Book
Michael Koss, Nafisa Aftab, Steven W. Allen +395
The AXIS Community Science Book represents the collective effort of 592 scientists worldwide to define the transformative science enabled by the Advanced X-ray Imaging Satellite (A…
A new model for the continuum spectra of AM CVn binaries and multi-messenger inference with normalizing flows
Nathan Steinle, Samar Safi-Harb, Austin MacMaster +5
The paper presents a forward model that connects the physical parameters of AM CVn ultra‑compact binaries to their X‑ray, optical, and ultraviolet continuum emission, and estimates…
Deciphering the Nature of the Pulsar Wind Nebula CTB 87 with XMM-Newton
Benson Guest, Samar Safi-Harb, Austin MacMaster +5
CTB 87 (G74.9+1.2) is an evolved supernova remnant (SNR) which hosts a peculiar pulsar wind nebula (PWN). The X-ray peak is offset from that observed in radio and lies towards the…
Simulation-calibrated Bayesian inference for progenitor properties of the microquasar SS 433
Nathan Steinle, Matthew Mould, Sarah Al-Humaikani +3
SS433 is one of the most extreme Galactic X-ray binaries, launching semi-relativistic jets and showing clear signs of super-critical accretion onto what is likely a black hole.…
