Dense, multi-phase accretion disk atmosphere in the low-luminosity state of black hole transientV4641 Sgr
Zuobin Zhang, Rob Fender, James H. Matthews +11
We present soft X-ray spectroscopy of the black-hole X-ray binary V4641~Sgr with the \textit{XMM-Newton} Reflection Grating Spectrometer (RGS). The RGS spectrum shows narrow emissi…
Bright flare in the obscured state of GRS 1915+105 as seen by NICER and Swift
Shuaitongze Zhao, Honghui Liu, Menglei Zhou +3
We report time-resolved NICER and Swift X-ray spectroscopy of a bright flare from the black hole X-ray binary GRS 1915+105 during its obscured state, which is characterized by heav…
First detection of X-ray polarization from the long-period X-ray pulsar 4U 1954+319
Alexander Salganik, Lingda Kong, Sofia V. Forsblom +6
We report the first detection of X-ray polarization with the Imaging X-ray Polarimetry Explorer from the X-ray pulsar (XRP) 4U 1954319. The source belongs to an extremely rare c…
Spin Constraints on 4U 1630-47 via combined Continuum Fitting and Reflection methods: a comparative study using Frequentist and Bayesian statistics
Debtroy Das, Honghui Liu, Zuobin Zhang +5
We present a comprehensive Bayesian spectral analysis of the black hole X-ray binary 4U 1630-47 during its 2022 outburst, using simultaneous NICER and NuSTAR observations. Using th…
Probing the emission geometry of the X-ray pulsar 2S 1417624 during a weak outburst with NICER, IXPE, and NuSTAR
Menglei Zhou, Pengju Wang, Honghui Liu +12
We report results from a multi-mission observational campaign of the transient X-ray pulsar 2S~1417624 during its 2025 outburst, using data from NICER, IXPE, and NuSTAR. Phase-a…
Probing the polarized emission from the accretion-powered pulsar 4U 1907+09 with IXPE
Menglei Zhou, Lorenzo Ducci, Honghui Liu +12
We present observations of the accretion-powered X-ray pulsar (XRP) 4U 1907+09, conducted with the Imaging X-ray Polarimetry Explorer (IXPE) that delivers the first high-quality po…
An IXPE-Led X-ray Spectro-Polarimetric Campaign on the Soft State of Cygnus X-1: X-ray Polarimetric Evidence for Strong Gravitational Lensing
James F. Steiner, Edward Nathan, Kun Hu +134
We present the first X-ray spectropolarimetric results for Cygnus X-1 in its soft state from a campaign of five IXPE observations conducted during 2023 May-June. Companion multiwav…
