On the emission of gamma rays by young pulsars
Abstract/Contents
- Abstract
- The gamma-ray emission from young rotation-powered pulsars has been studied in detail. The antenna patterns of emission are calculated for a variety of geometric emission models. These antenna patterns vary with magnetic inclination and spindown power; correspondingly, libraries of emission patterns are calculated across the phase space of possible parameter combinations. These libraries allow one to explore the possible gamma-ray light curves under a given model, for a given set of input parameters. A method of quantitative comparison was developed to allow the determination of a goodness-of-fit between an observed pulsar light curve and all of the possible simulated light curves for a given model. This method can localize the region of input parameter space that produces a model's best fit to an observed light curve. This can then be compared to external constraints on input parameters, often supplied by observations at other wavelengths (i.e., radio polarization and x-ray morphology). Finally, a simulation is run to reproduce the Galactic young pulsar population as faithfully as possible. Onto this population we apply the antenna patterns of various models in order to study the properties of the young gamma-ray pulsar population as a whole, constraining properties of the objects and evaluating the ability of the geometric gamma-ray models to reproduce the population-wide distributions of observables.
