Small-scale cosmic ray anisotropy observed by the GRAPES-3 experiment at TeV energies
M. Chakraborty, S. Ahmad, A. Chandra +35
GRAPES-3 is a mid-altitude (2200 m) and near equatorial ( North) air shower array, overlapping in its field of view for cosmic ray observations with experiments that…
The ASTRI Cherenkov Camera: from the prototype to the industrial version for the Mini-Array
G. Sottile, P. Sangiorgi, C. Gargano +37
The observation of energetic astronomical sources emitting very high-energy gamma-rays in the TeV spectral range (as e.g. supernova remnants or blazars) is mainly based on detectin…
The angular resolution of GRAPES-3 EAS array after correction for the shower front curvature
V. B. Jhansi, S. Ahmad, M. Chakraborty +22
The angular resolution of an extensive air shower (EAS) array plays a critical role in determining its sensitivity for the detection of point -ray sources in the multi-TeV energ…
The Atmospheric Monitoring system of the JEM-EUSO telescope
S. Toscano, A. Neronov, M. D. Rodríguez Frías +1
The JEM-EUSO observatory on board of the International Space Station (ISS) is a proposed pioneering space mission devoted to the investigation of Ultra High Energy Cosmic Rays (UHE…
An evaluation of the exposure in nadir observation of the JEM-EUSO mission
J. H. Adams, S. Ahmad, J. -N. Albert +258
We evaluate the exposure during nadir observations with JEM-EUSO, the Extreme Universe Space Observatory, on-board the Japanese Experiment Module of the International Space Station…
A next generation Ultra-Fast Flash Observatory (UFFO-100) for IR/optical observations of the rise phase of gamma-ray bursts
B. Grossan, I. H. Park, S. Ahmad +39
The Swift Gamma-ray Burst (GRB) observatory responds to GRB triggers with optical observations in ~ 100 s, but cannot respond faster than ~ 60 s. While some ground-based telescopes…
The JEM-EUSO Mission: Status and Prospects in 2011
EUSO Collaboration, J. H. Adams, S. Ahmad +256
Contributions of the JEM-EUSO Collaboration to the 32nd International Cosmic Ray Conference, Beijing, August, 2011.
Design and Fabrication of Detector Module for UFFO Burst Alert & Trigger Telescope
A. Jung, S. Ahmad, K. -B. Ahn +39
The Ultra-Fast Flash Observatory (UFFO) pathfinder is a space mission devoted to the measurement of Gamma-Ray Bursts (GRBs), especially their early light curves which will give cru…
The UFFO (Ultra Fast Flash Observatory) Pathfinder: Science and Mission
P. Chen, S. Ahmad, K. Ahn +39
Hundreds of gamma-ray burst (GRB) optical light curves have been measured since the discovery of optical afterglows. However, even after nearly 7 years of operation of the Swift Ob…
