The First X-Ray Polarimetry of an Eclipsing Low-Mass X-Ray Binary: Serendipitous IXPE Observation of AX J1745.6-2901

Romana Mikušincová, Lorenzo Marra, Hemanth Manikantan +38

We present the first X-ray polarimetric measurement of the neutron star low-mass X-ray binary system AX J1745.6-2901 conducted by the Imaging X-ray Polarimetry Explorer (IXPE) sate…

XRISM/Resolve reveals the complex iron structure of NGC 7213: Evidence for radial stratification between inner disk and broad-line region

E. Kammoun, T. Kawamuro, K. Murakami +48

We present the first high-resolution X-ray spectrum of NGC 7213 obtained with XRISM/Resolve, supported by simultaneous XMM-Newton, NuSTAR, and SOAR optical data. The XRISM spectrum…

Exploring MAXI J1744-294: IXPE insights into a Newly Discovered X-ray Transient

Lorenzo Marra, Romana Mikušincová, Federico M. Vincentelli +33

We present the first IXPE spectro-polarimetric observation of the black hole candidate MAXI J1744294, a transient X-ray source discovered during a bright 2025 outburst in the Ga…

A systematic search for AGN obscuration variability in the Chandra archive

Isaiah S. Cox, Núria Torres-Albà, Stefano Marchesi +5

The nature of the obscuring material in active galactic nuclei (AGN) can be studied by measuring changes in the line-of-sight column density, , over time. This can b…

20 years of disk winds in 4U 1630-47 -- I. Long-term behavior and influence of hard X-rays

M. Parra, S. Bianchi, P. -O. Petrucci +7

Highly ionized X-ray wind signatures have been found in the soft states of high-inclination Black Hole Low Mass X-ray Binaries (BHLMXBs) for more than two decades. Yet signs of a s…
