On the nature of the ultraluminous X-ray source Holmberg II X-1
F. Barra, C. Pinto, M. Middleton +4
We present a comprehensive spectral analysis of the ultraluminous X-ray source Holmberg II X-1 using broadband and high-resolution X-ray spectra taken with the XMM-Newton satellite…
A soft and transient ultraluminous X-ray source with 6-h modulation in the NGC 300 galaxy
A. Sacchi, P. Esposito, D. de Martino +13
We investigate the nature of CXOU J005440.5-374320 (J0054), a peculiar bright ( erg/s) and soft X-ray transient in the spiral galaxy NGC 300 with a 6-hour per…
The accretion/ejection link in the neutron star X-ray binary 4U 1820-30 I: A boundary layer-jet coupling?
A. Marino, T. D. Russell, M. Del Santo +16
The accretion flow / jet correlation in neutron star (NS) low-mass X-ray binaries (LMXBs) is far less understood when compared to black hole (BH) LMXBs. In this paper we will prese…
An ultrafast outflow in the black hole candidate MAXI J1810-222?
M. Del Santo, C. Pinto, A. Marino +9
The transient X-ray source MAXI J1810-222 was discovered in 2018 and has been active ever since. A long combined radio and X-ray monitoring campaign was performed with ATCA and Swi…
Transient obscuration event captured in NGC 3227 IV. Origin of the obscuring cloud variability
S. Grafton-Waters, J. Mao, M. Mehdipour +13
Obscuration events in type I active galactic nuclei (AGN) have been detected more frequently in recent years. The strong flux decrease in the soft X-ray band between observations h…
