Relativistic reflection within an extended hot plasma geometry
Alexey D. Nekrasov, Thomas Dauser, Javier A. Garcia +9
The reflection of X-rays at the inner accretion disk around black holes imprints relativistically broadened features in the observed spectrum. Aside from the black hole properties…
The nature of an imaginary quasi-periodic oscillation in the soft-to-hard transition of MAXI J1820+070
Candela Bellavita, Mariano Méndez, Federico García +2
A recent study shows that if the power spectra (PS) of accreting compact objects consist of a combination of Lorentzian functions that are coherent in different energy bands but in…
The X-ray Integral Field Unit at the end of the Athena reformulation phase
Philippe Peille, Didier Barret, Edoardo Cucchetti +279
The Athena mission entered a redefinition phase in July 2022, driven by the imperative to reduce the mission cost at completion for the European Space Agency below an acceptable ta…
Geometry of the comptonization region of MAXI J1348630 through type-C quasi-periodic oscillations with NICER
Kevin Alabarta, Mariano Méndez, Federico García +5
We use the rms and lag spectra of the type-C quasi-periodic oscillation (QPO) to study the properties of the Comptonisation region (aka corona) during the low/hard and hard-interme…
The Athena X-ray Integral Field Unit: a consolidated design for the system requirement review of the preliminary definition phase
Didier Barret, Vincent Albouys, Jan-Willem den Herder +296
The Athena X-ray Integral Unit (X-IFU) is the high resolution X-ray spectrometer, studied since 2015 for flying in the mid-30s on the Athena space X-ray Observatory, a versatile ob…
Modelling correlated variability in accreting black holes: the effect of high density and variable ionisation on reverberation lags
Guglielmo Mastroserio, Adam Ingram, Jingyi Wang +9
We present a new release of the RELTRANS model to fit the complex cross-spectrum of accreting black holes as a function of energy. The model accounts for continuum lags and reverbe…
