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…
Exploring the spin dependence on mass inclination and distance for the newly discovered black hole X-ray binary Swift J151857.0-572147
Yujia Song, James F. Steiner, Tong Zhao +7
The black hole X-ray binary (BHXRB) Swift J151857.0-572147 was discovered during its first outburst in March 2024. We review the archive of NICER observations from this outburst, f…
NICER Spectral and Timing Analysis of 4U 163047 and its Heartbeat State
Ningyue Fan, James F. Steiner, Cosimo Bambi +3
We present a spectral and timing analysis of NICER observations of the black hole X-ray binary 4U 1630-47 from 2018 to 2024. We find relativistic reflection features in the hard an…
The X-ray Integral Field Unit at the end of the Athena reformulation phase
Philippe Peille, Didier Barret, Edoardo Cucchetti +279
The Athena mission entered a redefinition phase in July 2022, driven by the imperative to reduce the mission cost at completion for the European Space Agency below an acceptable ta…
