Modeling surface radiation of rotating neutron stars with Monk-NS
Wenda Zhang, Wenfei Yu
Neutron stars serve as unique laboratories for studying ultra-dense nuclear matter. The equation of state of neutron star matter can be effectively constrained by their masses and…
Interaction between disk and extended corona in a general relativistic framework
Sudeb Ranjan Datta, Michal Bursa, Michal Dovciak +1
The energy equilibrium between the corona and the underlying disk in a two-phase accretion flow sets a lower limit on the achievable photon index. A slab corona may not explain the…
Possible Coronal Geometry in the Hard and Soft State of Black Hole X-ray Binaries from MONK Simulations
Ningyue Fan, Cosimo Bambi, James F. Steiner +1
Understanding the coronal geometry in different states of black hole X-ray binaries is important for more accurate modeling of the system. However, it is difficult to distinguish d…
Probing the Strong Gravity Region of Black Holes with eXTP
Qingcui Bu, Cosimo Bambi, Lijun Gou +42
We present the novel capabilities of the enhanced X-ray Timing and Polarimetry (eXTP) mission to study the strong gravity region around stellar-mass black holes in X-ray binary sys…
Dense Matter in Neutron Stars with eXTP
Ang Li, Anna L. Watts, Guobao Zhang +82
In this White Paper, we present the potential of the enhanced X-ray Timing and Polarimetry (eXTP) mission to constrain the equation of state of dense matter in neutron stars, explo…
First X-ray polarimetric view of a Low-Luminosity Active Galactic Nucleus: the case of NGC 2110
Sudip Chakraborty, Ajay Ratheesh, Daniele Tagliacozzo +20
Low-Luminosity Active Galactic Nuclei (LLAGN) provides a unique view of Comptonization and non-thermal emission from accreting black holes in the low-accretion rate regime. However…
