Beyond Disk Truncation: X-ray Reverberation Signatures of an Outflowing Corona

Ke Qin, Bei You, Adam Ingram +1

The corona in black hole X-ray binaries (BHXRBs) is likely dynamic during outbursts. A mildly relativistic outflowing corona has been proposed to explain hard spectra, weak disk re…

Supermassive Black Hole Winds in X-rays: SUBWAYS IV. Tracing Radio Emission and Unveiling the Role of Winds

E. Amenta, M. Brienza, G. Bruni +30

Most Active Galactic Nuclei (AGN) are Radio Quiet, with radio emission that may arise from star-formation activity, AGN-driven winds, weak jets, and coronal activity. Disentangling…

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…

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…

Characterisation of the stellar wind in Cyg X-1 via modelling of colour-colour diagrams

E. V. Lai, B. De Marco, Y. Cavecchi +11

Cygnus X-1 is a high mass X-ray binary where accretion onto the black hole is mediated by the stellar wind from the blue supergiant companion star HDE 226868. Depending on the posi…
