Search for pulsed multi-TeV gamma rays from the Crab pulsar using the Tibet-III air shower array
The Tibet AS Gamma Collaboration: M. Amenomori, et al
TL;DR
This study used the Tibet-III air shower array to search for pulsed multi-TeV gamma rays from the Crab pulsar but found no evidence, setting upper limits on such emissions across a broad energy range.
Contribution
It provides the first multi-TeV gamma-ray upper limits for the Crab pulsar using the Tibet-III array, constraining models of pulsar gamma-ray emission.
Findings
No pulsed gamma-ray signals detected.
Upper limits established for multi-TeV gamma-ray flux.
Results constrain theoretical models of pulsar emissions.
Abstract
We searched for pulsed gamma-ray emissions from the Crab pulsar using data of the Tibet-III air shower array from November 1999 through November 2005. No evidence for the pulsed emissions was found in our analysis. Upper limits at different energies were calculated for a confidence level in the energy range of multi-TeV to several hundred TeV.
