XMM-Newton multi-year campaign on NGC 55 ULX-1: Resolving the wind and its variability with RGS
C. Pinto, S. Caserta, F. Barra +12
Winds are an important ingredient in the evolution of X-ray binary (XRB) systems, particularly those at high accretion rates such as ultra-luminous X-ray sources (ULXs), because th…
A New Broadband Spectral State in the Ultraluminous X-ray Source Holmberg IX X-1
D. J. Walton, M. Bachetti, P. Kosec +12
We present a series of five new broadband X-ray observations of the ultraluminous X-ray source Holmberg IX X-1, performed by - and in coordination. The first…
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…
QPEs as Lense-Thirring precession of super-Eddington flows
M. Middleton, A. Gurpide, T. M. Kwan +9
Quasi-periodic eruptions (QPEs) are a recently identified class of X-ray transient associated with tidal disruption events by supermassive black holes, and for which there are mult…
