An X-ray Extremely wide-field Spectroscopic Surveyor (XESS, or "chess")
W. P. Maksym, M. Ulmer, S. Friedrich +20
We propose an X-ray observatory, the X-ray Extremely wide-field Spectroscopic Surveyor (XESS, pronounced "Chess") to bring high energy resolution X-ray spectroscopy into the era of…
X-ray polarization of the Compton-thin Seyfert galaxy NGC 5506 with IXPE
Daniele Tagliacozzo, Alessandro Leonardo Lai, Andrea Gnarini +14
We report on the observation of the Compton-thin Seyfert galaxy NGC~5506 performed with the Imaging X-ray Polarimetry Explorer (IXPE). The observation, with a net observing time of…
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…
X-ray polarization of Z-type neutron star low-mass X-ray binaries -- II. Spectropolarimetric analysis
Andrea Gnarini, Francesco Ursini, Giorgio Matt +8
IXPE has provided for the first time detailed energy- and time-resolved X-ray polarimetry of Z-type neutron star low-mass X-ray binaries (NS-LMXBs) as they move along their color-c…
X-Ray Polarization from the Gamma-Ray Binary LS I +61 303
Philip Kaaret, Sudip Chakraborty, Daniel Golonka +5
The gamma-ray emitting binary stellar system LS I +61 303 was observed with the Imaging X-ray Polarimetry Explorer (IXPE) on two successive orbits over orbital phases of 0.74 to 1.…
The first IXPE view of the eclipsing ADC source 4U 1822-37
A. Anitra, A. Gnarini, T. Di Salvo +17
Accretion-disc corona sources are high-inclination low-mass X-ray binaries in which the innermost regions are hidden and the observed X-ray emission is dominated by radiation scatt…
X-Ray Polarization from the Atoll 4U 1735-44 Suggests a Low Inclination
M. A. Díaz Teodori, A. Bobrikova, A. Gnarini +17
X-ray polarimetry is a new tool capable of probing the geometry of accretion onto weakly magnetized neutron stars. Here we present the first X-ray spectropolarimetric results from…
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…
Discovery of High X-Ray Polarization from the Neutron Star Low-Mass X-Ray Binary Cyg X-2 in the Horizontal Branch
Andrea Gnarini, Swati Ravi, Philip Kaaret +17
We present results from simultaneous X-ray polarimetric and spectroscopic observations of the bright neutron star low-mass X-ray binary Cyg X-2, performed by the Imaging X-ray Pola…
