Starting from the quadratic expansion in the photon fields of non-linear electrodynamics Lagrangian model, we study relevant vacuum properties in a scenario involving the propagation of a photon probe in the presence of a background constant magnetic field.
The vector $U$-bosons, or so-called 'dark photons', are potential candidates for dark matter mediators. They are expected to interact with standard matter via a 'vector portal' due to the $U(1)-U(1)^\prime$ symmetry group mixing, which may make them detectable in particle and heavy-ion experiments. Although there has been no confirmed observation of dark photons, detailed analyses of various...
We investigate the emission of gravitational waves from spheroidal, magnetized strange stars in two scenarios: an isolated, slowly rotating star and a binary system. For the isolated star, we compute the quadrupole moment and the amplitude of the gravitational waves that may be emitted. In the case of the binary system, we determine the tidal deformability by simultaneously solving the...
Hypercompact HII regions (HC) are regions of ionized gas associated with the earliest stages of high-mass star formation. With the aim of better understanding their characteristics, we have carried out a study of five candidates for HC HII regions. For this, we performed observations with the Jansky Very Large Array (JVLA) at 2 and 6 cm, with an angular resolution of ∼0.900 . As a result, we...
We study the thermodynamic properties of a relativistic magnetized scalar charged boson gas at any temperature in the presence of an external magnetic field. We reproduce the low temperature behavior of the boson gas characterized by two plateus of specific heat the first one at 1/2, the reduction on one dimensional gas due to the strong magnetic field provokes that all the bosons are in the...
