Aql X-1 from dawn 'til dusk: the early rise, fast state transition and decay of its 2024 outburst
A. Marino, F. Coti Zelati, K. Alabarta +36
Transient Low-Mass X-ray Binaries (LMXBs) are usually first detected by all-sky X-ray monitors when they enter new outbursts, typically at X-ray luminosities above 10…
The odyssey of the black hole low mass X-ray binary GX339-4: Five years of dense multi-wavelength monitoring
E. Tremou, S. Corbel, R. Fender +15
We present the longest and the densest quasi-simultaneous radio, X-ray and optical campaign of the black hole low mass X-ray binary GX339-4, covering five years of weekly GX339-4 m…
The peculiar hard state behaviour of the black hole X-ray binary Swift J1727.81613
A. K. Hughes, F. Carotenuto, T. D. Russell +37
Tracking the correlation between radio and X-ray luminosities during black hole X-ray binary outbursts is a key diagnostic of the coupling between accretion inflows (traced by X-ra…
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…
Optical and X-ray timing analysis of the 2018-2020 outburst and rebrightening of the black-hole transient MAXI J1820+070
M. Fiori, L. Zampieri, A. Burtovoi +15
We report the results of a comprehensive analysis of the multiwavelength (in optical and X-rays) and multitimescale (from months to tenths of a second) variability of the 2018-2020…
A new pulsating neutron star in the Ultraluminous X-ray source NGC 4559 X7?
F. Pintore, C. Pinto, G. Rodriguez-Castillo +17
Ultraluminous X-ray sources (ULX) are extragalactic objects with X-ray luminosities above the Eddington limit for a 10 Msun black hole (BH). ULXs may host super-Eddington accreting…
