Supermassive boson stars: prospects for observational detection
Diego F. Torres, S. Capozziello, G. Lambiase
In a recent work (Torres, Capozziello and Lambiase, Physical Review D62, 104012 (2000)), it was shown that a supermassive boson star could provide an alternative model for the gala…
Positional correlation between low-latitude gamma-ray sources and SNRs
Diego F. Torres, Jorge A. Combi, Gustavo E. Romero +1
We present the results of a spatial correlation analysis between unidentified gamma-ray sources in the 3EG catalog and candidates to supernova remnants. This work extends a previou…
Radiation from a uniformly accelerated charge in the outskirts of a wormhole throat
Luis A. Anchordoqui, S. Capozziello, G. Lambiase +1
Using traversable wormholes as theoretical background, we revisit a deep question of general relativity: Does a uniformly accelerated charged particle radiate? We particularize to…
Can the gamma-ray source 3EG J2033+4118 be produced by the stellar system Cyg OB2 No.5?
P. Benaglia, Gustavo E. Romero, I. R. Stevens +1
We discuss the possibility that the stellar system Cyg OB2 No.5 can be a gamma-ray source in the light of recent EGRET and radio data. This system is formed by an O7 Ia + Ofpe/WN9…
Non-extensivity Effects and the Highest Energy Cosmic Ray Affair
Luis A. Anchordoqui, Diego F. Torres
Recent measurements of the cosmic microwave background confirm that it is described by a Planckian distribution with high precision. It is non-extensivity bounded to be less than s…
Testing the Correlation of Ultra-High Energy Cosmic Rays with High Redshift Sources
Guenter Sigl, Diego Torres, Luis Anchordoqui +1
We study the correlation between compact radio quasars or 3EG gamma-ray blazars and the arrival directions of cosmic rays above 10^19 eV using an updated list of air shower detecti…
