Israel, GianLuca, Covino, Stefano, Mignani, Roberto, Stella, Luigi, Marconi, Gianni, Testa, Vincenzo, ...
The sky region including the Chandra position of SGR 1806-20 was monitored in the IR band during 2004, following its increased high energy bursting activity. Observations were performed using...
A new pseudo-Kaluza-Klein scheme for geometrical description of interactions (2005)
Cardone, Fabio, Marrani, Alessio, Mignani, Roberto
We illustrate the main features of a new Kaluza-Klein-like scheme (Deformed Relativity in five dimensions). It is based on a five-dimensional Riemannian space in which the four-dimensional space-time...
The electron mass from Deformed Special Relativity (2005)
Cardone, Fabio, Marrani, Alessio, Mignani, Roberto
Deformed Special Relativity (DSR) is a generalization of Special Relativity based on a deformed Minkowski space, i.e. a four-dimensional space-time with metric coefficients depending on the energy....
A geometrical meaning to the electron mass from breakdown of Lorentz invariance (2005)
Cardone, Fabio, Marrani, Alessio, Mignani, Roberto
We discuss the problem of the electron mass in the framework of Deformed Special Relativity (DSR), a generalization of Special Relativity based on a deformed Minkowski space (i.e. a four-dimensional...
Cardone, Fabio, Marrani, Alessio, Mignani, Roberto
In this paper, we continue the study of the Killing symmetries of a N-dimensional generalized Minkowski space, i.e. a space endowed with a (in general non-diagonal) metric tensor, whose coefficients...

Cardone, Fabio, Marrani, Alessio, Mignani, Roberto
In this paper, we introduce the concept of N-dimensional generalized Minkowski space, i.e. a space endowed with a (in general non-diagonal) metric tensor, whose coefficients do depend on a set of...
Boosts in an arbitrary direction and maximal causal velocities in a deformed Minkowski space (2005)
Cardone, Fabio, Marrani, Alessio, Mignani, Roberto
We discuss boosts in a deformed Minkowski space, i.e. a four-dimensional space-time with metric coefficients depending on non-metric coordinates (in particular on the energy). The general form of a...

Multiwavelength Study Of Two Unidentified Gamma-ray Sources (2004)
La Palombara, Nicola, Caraveo, Patrizia, Mignani, Roberto, Hatziminaoglou, Evanthia, Bignami, Giovanni F., Schirmer, Mischa
Most counterparts of the identified low-latitude gamma-ray sources are Isolated Neutron Stars (INSs). They are characterized by an extremely high value of the X/optical flux ratio, therefore a...
