EXPO: a quantum leap in fast, wide-band X-ray polarimetry for astrophysics
Paolo Soffitta, Sebastien Guillot, Ian Hutchinson +137
The Enhanced X-ray Polarimetry Observatory (EXPO) is a mission concept proposed to ESA as an M8 candidate, with a prospective launch in 2041. Building on the scientific success of…
Two Peas in a Pod: The First Confirmed Dual Active Galactic Nucleus within a Green Pea Galaxy System
Konstantinos Kouroumpatzakis, Peter G. Boorman, Jiří Svoboda +5
The growth of galaxies in the early Universe is thought to be dominated by compact, intensely star-forming systems, yet the corresponding growth of supermassive black holes (SMBHs)…
Blackholistic 2026 meeting report
Rob Fender, Jane Dai, Erin Kara +4
Accretion and relativistic jet formation take place across the black hole mass range, from black holes of just a few solar masses to those in excess of ten billion. Despite the eno…
Blueberry and Green Pea galaxies live in low density environments
Maitrayee Gupta, Jiří Svoboda, Konstantinos Kouroumpatzakis +3
Little is currently known about the large-scale environments of Green Pea (GP) and Blueberry (BB) galaxies, which are low-mass, compact systems with extreme specific star-formation…
Discovery of ultra-fast outflows with v in local bright active galactic nuclei
Laura Borrelli, Matteo Guainazzi, Giorgio Lanzuisi +5
Ultra-fast outflows (UFOs) are mildly relativistic (outflow velocity ) nuclear winds detected as blueshifted absorption lines from highly ionized, dense gas in the X-…
Systematic assessment of disk truncation in the black hole X-ray binary Swift J1727.8-1613 using NICER
Ole König, James F. Steiner, Niek Bollemeijer +20
The 2023/24 NICER monitoring campaign of the 7 Crab bright black hole X-ray binary Swift J1727.8-1613 covered the outburst in almost all accretion states. High-quality data are ava…
Discovery of Strong Energy-Dependent X-ray Polarization in the Intermediate State of GS 1354-64
Swati Ravi, Lorenzo Marra, James F. Steiner +20
We report the discovery of significant X-ray polarization from the dynamically confirmed black hole X-ray binary (BHXB) GS 1354-64 during its 2025-2026 outburst, obtained with the…
XPE and VLT /FORS2 polarimetry challenge the Seyfert-1.9 classification of MCG-05-23-16
Frédéric Marin, Daniele Tagliacozzo, Francesco Ursini +21
We report the third observation of the Seyfert-1.9 active galactic nucleus (AGN) MCG-05-23-16 with the Imaging X-ray Polarimetry Explorer (\textit{IXPE}), together with optical spe…
