Estimating the size of X-ray lamppost coronae in active galactic nuclei

. However, the corona must intercept a number of optical/UV seed photons from the disc in the lamppost geometry. In this commonly adopted scenario, the corona is assumed corona can generally exist, but with constra...

Dynamic of an Al wire corona of a megaampere Z-pinch.

It is shown that the development of instabilities in a Z-pinch plasma formed by loading a relatively thick Al wire is slowed down due to the high plasma density in the wire corona. X-ray pulses with a photon energy of several keV an...

The dynamics of and radiation from a copper-wire corona in a megaampere Z-pinch.

Evolution of the extreme ultraviolet and soft X-ray emission in the 50- to 2000-eV photon energy range from a plama corona formed by loading a relatively thivk Cu wire was observed in a Z-pinch discharge with a maximum current of 2 ...

Hot Coronae in Local AGN: Present Status and Future Perspectives

The nuclear X-ray emission in radio-quiet Active Galactic Nuclei (AGN) is commonly believed to be due to inverse Compton scattering of soft UV photons in a hot corona. The radiation is expected to be polarized, the polarization degr...

On the high energy cut-off of accreting sources: Is general relativity relevant?

to be produced by inverse Compton scattering of soft photons arising from the accretion disc by energetic electrons thermally distributed above the disc, the so-called X-ray corona. Many independent observations suggest that such <...

Core-corona effect in hadron collisions and muon production in air showers

It is well known that the fraction of energy in a hadron collision going into electromagnetic particles (electrons and photons, including those from decays) has a large) in addition to the expected string fragmentation (corona). Sin...
