Compton-Getting effect due to terrestrial orbital motion observed on cosmic ray flow from Mexico-city Neutron Monitor
Carlos Navia, Marcel de Oliveira, Andre Nepomuceno
We look for a diurnal anisotropy in the cosmic ray flow, using the Mexico-City Neutron Monitor (NM) detector, due to the Earth's orbital motion and predicted by Compton-Getting (C-…
Alignment of air showers produced by ultra-high energy cosmic rays at the Pierre Auger Observatory
Carlos Navia, Marcel de Oliveira, Andre Nepomuceno
We show that the energy-weighted angular (zenith, azimuth) distribution of extensive air showers (EAS), produced by Ultra High Energy (UHE) cosmic rays at the Pierre Auger Observat…
On the short term modulation of cosmic rays by high-speed streams at the Pierre Auger surface array detectors
M. N. de Oliveira, C. R. A. Augusto, C. E. Navia +1
We present an analysis of the short-term modulation (one rotation of Bartels-27 days) of the galactic cosmic rays (GCR) by the solar wind, based on the cosmic ray rates observed by…
Possible GeV counterpart at the ground level associated with Fermi LAT gamma-ray bursts
C. R. A. Augusto, C. E. Navia, M. N. de Oliveira +3
From June 2014 to February 2017, the Fermi LAT detected 46 gamma-ray bursts (GRBs) with photon energies above 20 MeV, and the trigger coordinates of seven of them were within the F…
Prompt emission from GRB 150915A in the GeV energy range detected at ground by the New-Tupi detector: A review
C. R. A. Augusto, C. E. Navia, M. N. de Oliveira +3
Since 2014, a new detector (New-Tupi) consisting of four plastic scintillators () placed in pairs and located in Niteroi, Rio de Janeiro, Brazil, has b…
Plasma Pressure Driven Asymmetric Supernovae and Highly Collimated Gamma-Ray Bursts
K. H. Tsui, C. E. Navia
During the process of collapse of a massive star, a cavity is generated between the central iron core and an outer stellar envelope. The dynamics of this cavity, filled with plasma…
