The High Energy X-ray Probe (HEX-P): Studying Extreme Accretion with Ultraluminous X-ray Sources
Matteo Bachetti, Matthew J. Middleton, Ciro Pinto +25
Ultraluminous X-ray sources (ULXs) represent an extreme class of accreting compact objects: from the identification of some of the accretors as neutron stars to the detection of po…
Tormund's return: Hints of quasi-periodic eruption features from a recent optical tidal disruption event
E. Quintin, N. A. Webb, S. Guillot +8
Quasi-periodic eruptions (QPEs) are repeating thermal X-ray bursts associated with accreting massive black holes, the precise underlying physical mechanisms of which are still uncl…
Observing the onset of the accretion wake in Vela X-1
C. M. Diez, V. Grinberg, F. Fürst +7
High-Mass X-ray Binaries (HMXBs) offer a unique opportunity for the investigation of accretion onto compact objects and of wind structure in massive stars. A key source for such st…
The ultraluminous X-ray source M81 X-6: a weakly magnetised neutron star with a precessing accretion disc?
Roberta Amato, Andres Gúrpide, Natalie A. Webb +2
We investigate the nature of the ULX M81 X-6, which has been suggested to harbour a neutron star (NS), by studying its long-term X-ray spectral and temporal evolution, using the ri…
Disk precession to explain the super-orbital modulation of LMC X-4: results from the Swift monitoring campaign
Elena Ambrosi, Antonino d'Aì, Melania del Santo +4
We studied the spectral changes of the high-mass X-ray binary system LMC X-4 to understand the origin and mechanisms beyond its super-orbital modulation (30.4 days). To this aim, w…
Looking through the photoionisation wake: Vela X-1 at with Chandra/HETG
R. Amato, V. Grinberg, N. Hell +6
The Supergiant X-ray binary Vela X-1 represents one of the best astrophysical sources to investigate the wind environment of a O/B star irradiated by an accreting neutron star. Pre…
Search for multiwavelength emission from the binary millisecond pulsar PSR J1836-2354A in the globular cluster M22
R. Amato, A. D'Aì, M. Del Santo +5
We present a multi-band search for X-ray, optical and -ray emission of the radio binary millisecond pulsar J1836-2354A, hosted in the globular cluster M22. X-ray emission is sig…
