Compact X-ray sources: X-ray from self-reflection
X-ray has been an important scientific tool ever since its discovery in the 1890s. X-ray used to be generated by synchrotron machines, which are large and expensive devices. However, laser-based particle acceleration offers a way to reduce the size and cost of hard-X-ray sources. Scientists have now developed a simple scheme that produces a bright flash of hard-X-rays by using a single laser pu...
متن کاملRelativistic Disk Reflection in the Neutron Star X-ray Binary Xte J1709-267 with Nustar
We perform the first reflection study of the soft X-ray transient and Type 1 burst source XTE J1709-267 using NuSTAR observations during its 2016 June outburst. There was an increase in flux near the end of the observations, which corresponds to an increase from ∼0.04 LEdd to ∼0.06 LEdd assuming a distance of 8.5 kpc. We have separately examined spectra from the low and high flux intervals, whi...
متن کاملX - ray reflection spectra from ionized slabs
X-ray reflection spectra are an important component in the X-ray spectra of many active galactic nuclei and Galactic black hole candidates. It is likely that reflection takes place from highly ionized surfaces of the accretion disc in some cases. This can lead to strong Comptonization of the emergent iron, and other, absorption and emission features. We present such reflection spectra here, com...
متن کاملMultiple X-ray reflection from ionized slabs
Multiple reflection of X-rays may be important when an accretion disc and its hot corona have a complicated geometry, or if returning radiation due to gravitational light bending is important, or in emission from a funnel such as proposed in some gamma-ray burst models. We simulate the effects of multiple reflection by modifying the boundary condition for an X-ray illuminated slab. Multiple ref...
