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…
Rapid onset of a Comptonisation zone in the repeating tidal disruption event XMMSL2 J140446.9-251135
R. D. Saxton, T. Wevers, S. van Velzen +11
We report here on observations of a tidal disruption event, XMMSL2 J1404-2511, discovered in an XMM-Newton slew, in a quiescent galaxy at z=0.043. X-ray monitoring covered the epoc…
The NICER view of Scorpius X-1
J. López-Miralles, S. E. Motta, J. C. A. Miller-Jones +3
The Neutron Star X-ray binary Sco X-1 is one of the brightest Z-type sources in our Galaxy, showing frequent periods of flaring activity and different types of relativistic outflow…
Euclid Quick Data Release (Q1). The active galaxies of Euclid
Euclid Collaboration, T. Matamoro Zatarain, S. Fotopoulou +355
We present a catalogue of candidate active galactic nuclei (AGN) in the Quick Release (Q1) fields. For each source we collect multi-wavelength photometry and spec…
NICER observations of type-I X-ray bursts from the ultra-compact X-ray binary M15 X-2
María Alejandra Díaz Teodori, Jari J. E. Kajava, Celia Sánchez-Fernández +3
Type-I X-ray bursts are thermonuclear explosions caused by the unstable burning of accreted material on the surface of neutron stars. We report the detection of seven type-I X-ray…
Fragments of harmony amid apparent chaos: a closer look at the X-ray quasi-periodic eruptions of the galaxy RX J1301.9+2747
Margherita Giustini, Giovanni Miniutti, Riccardo Arcodia +17
Quasi-periodic eruptions (QPEs) are an extreme X-ray variability phenomenon associated with low-mass supermassive black holes. First discovered in the nucleus of the galaxy GSN 069…
