Guillemot et al. recently reported the discovery of $\gamma$-ray pulsations from the 22.7ms pulsar (pulsar A) in the famous double pulsar system J0737-3039A/B. The $\gamma$-ray light curve (LC) of pulsar A has two peaks separated by…
We analytically examine the capabilities of rotation-powered pulsars as the sources of gamma-rays and show that their phase-averaged gamma-ray flux is proportional to the product of the spin-down flux and the gap trans-field thickness cubed…
The predictive power of the outer gap model of high energy emission from pulsars is used to analyze the Parkes Multibeam pulsar survey. We find that most of the radio pulsars of the Parkes catalog are not $\gamma$-ray emitters according to…
