The Athena space X-ray Observatory and the astrophysics of hot plasma
Didier Barret, Anne Decourchelle, Andy Fabian +4
The properties (temperature, density, chemical composition, velocity) of hot astrophysical plasma and the physical processes affecting them (heating/cooling, turbulence, shocks, ac…
Discovery of a soft X-ray lag in the Ultraluminous X-ray Source NGC 1313 X-1
E. Kara, C. Pinto, D. J. Walton +14
Ultraluminous X-ray Sources (ULXs) provide a unique opportunities to probe the geometry and energetics of super-Eddington accretion. The radiative processes involved in super-Eddin…
The nature of the broadband X-ray variability in the dwarf Seyfert galaxy NGC 4395
E. S. Kammoun, E. Nardini, A. Zoghbi +14
We present a flux-resolved X-ray analysis of the dwarf Seyfert 1.8 galaxy NGC 4395, based on three archival and one archival observations. The source is known…
MAXI J1820+070 with NuSTAR I. An increase in variability frequency but a stable reflection spectrum: coronal properties and implications for the inner disc in black hole binaries
D. J. K. Buisson, A. C. Fabian, D. Barret +10
MAXI J1820+070 (optical counterpart ASASSN-18ey) is a black hole candidate discovered through its recent very bright outburst. The low extinction column and long duration at high f…
Thermal X-ray emission identified from the millisecond pulsar PSR J1909-3744
N. A. Webb, D. Leahy, S. Guillot +5
Pulsating thermal X-ray emission from millisecond pulsars can be used to obtain constraints on the neutron star equation of state, but to date only five such sources have been iden…
Inferring black hole spins and probing accretion/ejection flows in AGNs with the Athena X-ray Integral Field Unit
Didier Barret, Massimo Cappi
Active Galactic Nuclei (AGN) display complex X-ray spectra which exhibit a variety of emission and absorption features, that are commonly interpreted as a combination of i) a relat…
