High performance Stingray

Eleonora Veronica Lai, Matteo Bachetti, Maura Pilia +4

X-ray astrophysical objects show variability on a wide range of timescales, i.e. from fractions of second to years. The open-source Python library stingray is able to perform time…

Studying the Variable Continuum and Emission Line Spectrum of 4U 1700-377 using NuSTAR's Stray Light

Colin J Bourque, McKinley C Brumback, Brian W Grefenstette +4

The high-mass X-ray binary 4U 1700-377 shows strong variation in brightness on timescales of hundreds of seconds due to accretion from a highly clumped stellar wind from the compan…

Emulation of non-linear 1D spectral models: relativistic X-ray reflection

Benjamin J. Ricketts, Tin Hadži Veljković, Daniela Huppenkothen +4

The use of machine learning techniques to approximate computationally expensive models has become increasingly prevalent in a wide variety of fields within astronomy. We discuss th…

The strength of Type-C quasi-periodic oscillations in black hole X-ray binaries correlates with the jet inclination

F. M. Vincentelli, N. Bollemeijer, A. Veledina +10

X-ray quasi-periodic oscillations (QPOs) are a characteristic feature of low-mass X-ray binaries (LMXBs). These oscillations have been studied for decades and revealed a rich and c…

Dust grain chemistry in the diffuse ISM towards the black hole transient GX 339-4

I. Psaradaki, L. Corrales, E. Costantini +10

We present results on X-ray absorption and the dust grain chemistry in the diffuse interstellar medium (ISM), based on a new Cycle 25 Chandra High Energy Transmission Grating Spect…

Systematic assessment of disk truncation in the black hole X-ray binary Swift J1727.8-1613 using NICER

Ole König, James F. Steiner, Niek Bollemeijer +20

The 2023/24 NICER monitoring campaign of the 7 Crab bright black hole X-ray binary Swift J1727.8-1613 covered the outburst in almost all accretion states. High-quality data are ava…

NuSTAR's Intentional Stray Light Observation of Scorpious X-1

S. Li, R. M. Ludlam, M. Sudha +8

We present the first spectral analysis of Scorpius X-1 (Sco X-1) using intentional stray light (SL) observations taken by NuSTAR. Unlike focused observations that have high telemet…

Discovery of Strong Energy-Dependent X-ray Polarization in the Intermediate State of GS 1354-64

Swati Ravi, Lorenzo Marra, James F. Steiner +20

We report the discovery of significant X-ray polarization from the dynamically confirmed black hole X-ray binary (BHXB) GS 1354-64 during its 2025-2026 outburst, obtained with the…
