Spectral and polarization properties of black hole accretion disc emission: including absorption effects
Roberto Taverna, Lorenzo Marra, Stefano Bianchi +5
The study of radiation emitted from black hole accretion discs represents a crucial way to understand the main physical properties of these sources, and in particular the black hol…
Strongly pulsed thermal X-rays from a single extended hot spot on PSR J2021+4026
Michela Rigoselli, Sandro Mereghetti, Roberto Taverna +2
The radio-quiet pulsar PSR J2021+4026 is mostly known because it is the only rotation-powered pulsar that shows variability in its γ-ray emission. Using XMM-Newton archival data, w…
3D modelling of magneto-thermal evolution of neutron stars: method and test cases
Davide De Grandis, Roberto Turolla, Toby S. Wood +3
Neutron stars harbour extremely strong magnetic fields within their solid outer crust. The topology of this field strongly influences the surface temperature distribution, and henc…
Towards a complete description of spectra and polarization of black hole accretion disks: albedo profiles and returning radiation
Roberto Taverna, Wenda Zhang, Michal Dovčiak +4
Accretion disks around stellar-mass black holes (BHs) emit radiation peaking in the soft X-rays when the source is in the thermal state. The emerging photons are polarized and, for…
X-ray spectra and polarization from magnetar candidates
Roberto Taverna, Roberto Turolla, Valery Suleimanov +2
Magnetars are believed to host the strongest magnetic fields in the present universe ( G) and the study of their persistent emission in the X-ray band offers an un…
