On external shock model to explain the high-energy emission: GRB 940217, GRB 941017 and GRB 970217A
N. Fraija, M. M. Gonzalez, J. L. Ramirez +2
We present a leptonic model on the external shock context to describe the high-energy emission of GRB 940217, GRB 941017 and GRB 970217A. We argue that the emission consists of two…
Hadronic processes as origin of TeV emission in Fanaroff-Riley Class I: Cen A, M87 and NGC1275
N. Fraija, M. M. Gonzalez, M. Perez
Recent detections of Fanaroff-Riley Class I AGNs by HESS, MAGIC, and VERITAS suggest that very-high-energy gamma-rays (VHE, E > 100 GeV) may not have a leptonic origin. We present…
Long and short high energy components presented in GRBs
N. Fraija, M. M. Gonzalez, R. Sacahui +1
We present a leptonic model on the external shock framework to describe the long- and short- lasting GeV component of some GRBs. This model was already applied successfully to GRB…
How many Ultra High Energy Cosmic Rays could we expect from Centaurus A?
Nissim fraija, M. M. Gonzalez, M. Perez +1
The Pierre Auger Observatory has associated a few ultra high energy cosmic rays with the direction of Centaurus A. This source has been deeply studied in radio, infrared, X-ray and…
SSC Emission as the Origin of the Gamma Ray Afterglow Observed in GRB 980923
Nissim Fraija, M. Magdalena Gonzalez, Willian H. Lee
GRB 980923 was one of the brightest bursts observed by the Burst and Transient Source Experiment (BATSE). Previous studies have detected two distinct components in addition to the…
