On detecting oscillations of gamma rays into axion-like particles in turbulent and coherent magnetic fields

Manuel Meyer, Daniele Montanino, Jan Conrad

Background radiation fields pervade the Universe, and above a certain energy any -ray flux emitted by an extragalactic source should be attenuated due to pair productio…

XMM-Newton and Swift observations of WZ Sge: spectral and timing analysis

A. A. Nucita, E. Kuulkers, F. De Paolis +3

WZ Sagittae is the prototype object of a subclass of dwarf novae, with rare and long (super)outbursts, in which a white dwarf primary accretes matter from a low mass companion. Hig…

Probing the radio emission from air showers with polarization measurements

Pierre Auger Collaboration

The emission of radio waves from air showers has been attributed to the so-called geomagnetic emission process. At frequencies around 50 MHz this process leads to coherent radiatio…
