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…

A multiwavelength study of the Galactic center black hole candidate MAXI J1744-294

Shifra Mandel, Kaya Mori, Paul A. Draghis +37

For the first time in nearly a decade, a bright transient was detected in the central parsec (pc) of the Galaxy. MAXI J1744-294, or -- as it was known in its previous life -- Swift…

The CUbesat Solar Polarimeter (CUSP): mission overview II

Sergio Fabiani, Ettore Del Monte, Andrea Alimenti +46

The CUbesat Solar Polarimeter (CUSP) project is an Earth-orbiting CubeSat mission designed to measure the linear polarization of solar flares in the hard X-ray band using a Compton…

X-ray polarization of reflected thermal emission

J. Podgorný, M. Dovčiak, R. Goosmann +5

We compute rest-frame reflection spectra and the corresponding energy-dependent linear polarization degree and angle for (un)polarized single-temperature blackbody spectra impingin…

Polarization properties of thermal accretion disk emission. I. Direct radiation

L. Marra, J. Podgorný, R. Taverna +4

The X-ray polarimetric observing window re-opening is shedding new light on our current understanding of compact accreting sources. This is true, in particular, for stellar-mass bl…

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…

The very high X-ray polarisation of accreting black hole IGRJ17091-3624 in the hard state

Melissa Ewing, Maxime Parra, Guglielmo Mastroserio +26

We report the first detection of the X-ray polarisation of the transient black hole X-ray binary IGRJ17091-3624 taken with the Imaging X-ray polarimetry Explorer (IXPE) in March 20…
