The Hubble diagram of high redshift objects, QSOs and AGNs
C. E. Navia, C. R. A. Augusto, K. H. Tsui
According to the Hubble law, high redshift objects such as Quasar (QSOs), X-ray Active Galactic Nuclei (AGN) together with the Gamma Ray Burst (GRBs) are the fastest and farthest o…
Effects of the South Atlantic Anomaly on the muon flux at sea level
C. R. A. Augusto, J. B. Dolival, C. E. Navia +1
The goal of this study is to examine the response and changes of the muon intensity at ground, due to magnetic anomaly over south Atlantic. Based on the data of two directional muo…
Time-dependent magnetohydrodynamic self-similar extragalactic jets
K. H. Tsui, A. Serbeto
Extragalactic jets are visualized as dynamic erruptive events modelled by time-dependent magnetohydrodynamic (MHD) equations. The jet structure comes through the temporally self-si…
On the ultra high energy cosmic rays and the origin of the cosmic microwave background radiation
C. E. Navia, C. R. A. Augusto, K. H. Tsui
Some inconsistencies to the assumption of a cosmological origin of the cosmic microwave background CMB, such as the absence of gravitational lensing in the WMAP data, open the door…
Evidences of high energy protons with energies beyond 0.4 GeV in the solar particle spectrum as responsible for the cosmic rays solar diurnal anisotropy
C. E. Navia, C. R. A. Augusto, M. B. Robba +1
Analysis on the daily variations of cosmic ray muons with based on the data of two directional muon telescopes at sea level and with a rigidity of response to cos…
Inter-galactic gravitational field effect on the propagation of light
C. E. Navia, C. R. A. Augusto, D. F. Franceschini +1
Recent observations of the luminosity-redshift in Type Ia supernovae suggest an accelerated inflation of the Universe (open Universe) as well as the observed matter density showed…
