The light emitted by all galaxies across the history of the Universe is encoded in the intensity of the extragalactic background light (EBL), the diffuse cosmic radiation field at ultraviolet, optical, and infrared wavelengths. The EBL is a source of opacity for very high energy gamma rays via pair production, leaving a characteristic attenuation

The phenomenon of magnetic reconnection in a magnetized plasma has been a subject of numerous studies over the past several decades in a variety of contexts, from high energy astrophysics, to solar and space physics, to laboratory-based experiments. However, most magnetic reconnection studies have been devoted to exploring different collisionality

Se presenta el criostato de pruebas con el que se realizará la integración y verificación de la Preóptica de Harmoni (Espectrógrafo de primera luz del ELT). Una vez realizada la integración de la preóptica, el criostato pasará a ser de uso común y se podrá utilizar para pruebas en criogenia y vacío de instrumentos planos de gran formato.
