Pulse profiles of accreting neutron stars - A review of analysis methods, observations, and theoretical models
Katja Pottschmidt, Peter Kretschmar, Ekaterina Sokolova-Lapa +25
X-ray pulsars are highly magnetized ( G) neutron stars accreting from a donor star. Their characteristic X-ray emission arises from accreted material decelerated fro…
GeoCache: Training-Free Acceleration of Multi-View Texture Diffusion via Geometric Delta Transport
Haotang Li, Zhenyu Qi, Shaohan Henry Wang +6
Geometry-conditioned multi-view diffusion enables high-quality 3D texture generation, but its repeated per-view denoiser evaluations introduce substantial computational cost. Exist…
The emergence of X-ray emission lines during relativistic radio-jet formation in the changing-look active galactic nucleus 1ES 1927+654
Dev R. Sadaula, Sibasish Laha, Eileen T. Meyer +27
We present results from a comprehensive multi-wavelength monitoring campaign of the changing-look active galactic nucleus 1ES 1927+654 during the onset and evolution of a relativis…
Chemical enrichment of the Perseus cluster core seen by XRISM/Resolve
XRISM Collaboration, Marc Audard, Hisamitsu Awaki +147
The intracluster medium (ICM) is rich in chemical elements, produced by core-collapse (SNcc) and Type Ia supernovae (SNIa) over the last 12 Gyr. Whereas cluster outskirts are…
Spectroscopic modeling of ionic structure in stellar winds of high-mass X-ray binaries
G. Sanjurjo-FerrÃn, V. Grinberg, I. El Mellah +6
High-mass X-ray binaries (HMXBs) provide a natural laboratory to study radiatively driven stellar winds under strong external X-ray irradiation. As the compact object moves along i…
The line modulations of H-like Fe, Ca, Ar, and S observed with /Resolve in Cyg X-3
Tomohiro Hakamata, Hirokazu Odaka, Ryota Tomaru +13
Cygnus X-3, hosting a Wolf-Rayet (WR) star whose dense wind produces various spectral lines due to photoionization by X-rays from a compact object, provides an ideal laboratory for…
