Unveiling the biconical geometry of the outflow in the ultraluminous X-ray source NGC 5204 X-1
S. Caserta, C. Pinto, T. Di Salvo +9
Ultraluminous X-ray sources (ULXs) are non-nuclear X-ray binary systems that exceed the Eddington luminosity for a 10 Msun black hole. The majority of these sources are thought to…
CubeSats Reach the Millisecond X-Ray Domain: Crab Pulsar Timing with SpIRIT/HERMES
Wladimiro Leone, R. Mearns, T. Di Salvo +70
The High Energy Rapid Modular Ensemble of Satellites (HERMES) instrument is a compact X/-ray spectrometer operating on board the 6U (11 kg) SpIRIT CubeSat. The payload is partic…
Flashing fast: characterising the 2025 outburst of MAXI J1957+032
A. Sanna, G. Illiano, M. C. Baglio +13
MAXI J1957+032 is an accreting millisecond X-ray pulsar that shows brief, recurrent outbursts in an ultra-compact ~1 h orbit. We characterise the 2025 outburst using X-ray timing a…
An ultraviolet burst oscillation candidate from the low-mass X-ray binary EXO 0748-676
A. Miraval Zanon, F. Ambrosino, G. Illiano +15
X-ray burst oscillations are quasi-coherent periodic signals at frequencies close to the neutron star spin frequency. They are observed during thermonuclear Type I X-ray bursts fro…
Time domain astrophysics with transient sources. Delay estimate via Cross Correlation Function techniques
W. Leone, L. Burderi, T. di Salvo +10
The timing analysis of transient events allows for investigating numerous still open areas of modern astrophysics. The article explores all the mathematical and physical tools requ…
On the nature of the X-ray binary transient MAXI J1834-021: clues from its first observed outburst
A. Manca, A. Marino, A. Borghese +14
MAXI J1834-021 is a new X-ray transient that was discovered in February 2023. We analysed the spectral and timing properties of MAXI J1834-021 using NICER, NuStar and Swift data co…
