A Systematic Study of Type Ia Supernova Remnants: Using Nucleosynthesis to Probe their Supernova Progenitors
Cole Treyturik, Samar Safi-Harb, Gilles Ferrand
We present the first systematic, spatially resolved X-ray spectroscopic study of a largely thermonuclear (Type Ia) sample of supernova remnants (SNRs), aimed at probing the explosi…
The G347.3-0.5 outlier from O3: a follow-up case study for continuous gravitational-wave candidates
L. Mirasola, F. Amicucci, M. Carrio +31
We report a multi-pipeline follow-up study of the continuous gravitational-wave (CW) outlier identified by the Ming et al. Einstein@Home directed search for the young supernova rem…
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…
Constraining Disk-to-Corona Power Transfer Fraction, Soft X-ray Excess Origin, and Black Hole Spin Population of Type-1 AGN across Mass Scales
Labani Mallick, Ciro Pinto, John Tomsick +6
Understanding the nature of the accretion disk, its interplay with the X-ray corona, and assessing black hole spin demographics remain open challenges in astrophysics. In this pape…
A MUSE View of the Optical Torus within the Supernova Remnant 1E 0102.2-7219
Janette Suherli, Samar Safi-Harb, Ivo R. Seitenzahl +7
We present new MUSE Narrow Field Mode with Adaptive Optics observations of the optical torus surrounding a Central Compact Object (CCO) candidate within the oxygen-rich supernova r…
The Western Jet of SS 433/W50: Hard X-ray Emission, Spectral Evolution, and Comparison to the Eastern Jet
Brydyn Mac Intyre, Samar Safi-Harb, Dmitry Khangulyan +5
The W50 nebula powered by the microquasar SS 433 is a unique laboratory for exploring several fundamental astrophysical phenomena. This study presents observations from NuSTAR and…
