Composition-dependent acceleration of UHE Cosmic Rays in AGN electric fields

E. Koutsoumpou, I. Contopoulos, A. Nathanail +2

The origin of ultra-high-energy cosmic rays (UHECRs) remains elusive, as proposed acceleration mechanisms are rarely connected directly to composition-sensitive air-shower observab…

Gravitational Waves from the Pulsar Magnetosphere

Ioannis Contopoulos, Demosthenes Kazanas, Demetrios B. Papadopoulos

We investigate the generation of gravitational waves from the rotation of an orthogonal pulsar magnetosphere in flat space time. We calculate the first order metric perturbation du…

Interference with non-interacting free particles and a special type of detector

Ioannis Contopoulos, Athanasios C. Tzemos, Foivos Zanias +1

We develop a classical picture of interference for non-interacting individual classical massive free particles. As long as they remain undetected, particles carry the information o…

Quantum Mechanics: reality or an illusion of the detector? Paper I: Interference with non-interacting photons and a special type of detector

Ioannis Contopoulos

We present a statistical model of non-interacting individual classical particles that may lead to a microscopic implementation of quantum mechanics. The model requires the action o…

Gravitational Waves from GRB Core Spindown

Ioannis Contopoulos, Achilles Strantzalis, Dimitrios Papadopoulos +1

We investigate long Gamma-Ray Bursts (GRB) which manifest a sharp linear rise followed by an exponential decay in their gamma-ray prompt emission observed with the BAT instrument o…

An underlying universal pattern in galaxy halo magnetic fields

Ioannis Myserlis, Ioannis Contopoulos

Magnetic fields in galaxy halos are in general very difficult to observe. Most recently, the CHANG-ES collaboration (Continuum HAlos in Nearby Galaxies - an EVLA Survey) investigat…
