Conditions for use of two-dimensional photon-counting detectors in Speckle interferometry.
The microchannel plates, on which are based the operation of two-dimensional photon-counting detectors, have a local dead time (at each microchannel) much...
Cones of Ionizing Radiation in Active Galaxies - Probing the Central Engine
Highly ionized gas has been detected at large distances from the nucleus in several classes of active galaxies. There is evidence that photoionization by the...
Cones of ionizing radiation in Seyfert galaxies: probing the central engine.
Highly ionized large scale structures have recently been observed in many active galaxies. There is evidence that photoionization by the active nucleus may be...
