At WIPAC, Juan Carlos Díaz-Vélez leads the simulation production for IceCube, but he has also been busy as a PhD candidate of the Universidad de Guadalajara in Mexico. Yesterday, the Centro Universitario de los Valles (CUVALLES) in Guadalajara awarded him the best post-graduate thesis in 2017, acknowledging his contributions to the study of cosmic rays with HAWC and IceCube.
In a study published today in the journal Physical Review D, HAWC announces a measurement of the cosmic-ray energy spectrum in the energy range of 10 to 500 TeV, bridging measurements at higher energy usually performed by ground based detectors and measurements at lower energy that previously had been conducted by detectors on satellites and balloons.
The HAWC Collaboration has made the first detailed measurements of two pulsars touted as possible sources of the positron excess observed in 2008 by the spaceborne detector AMS-02. By catching and counting particles of light streaming forth from these nearby stellar engines, reserachers have showed that these two pulsars are very unlikely to be the origin of the excess. The results are published today in Science.
