چکیده

We suggest a technique for construction of profiles of incoherent pulsar emission using instantaneous angular distribution indicatrix of radiation from relativistic source moving in the neutron star magnetosphere. In the general case the indicatrix depends on the kinematic parameters of radiation source such as velocity and acceleration. The method is illustrated by calculation of the profiles of pulsar radiation based on synchrotron radiation indicatrix. This technique can be easily generalized for the case of other types of relativistic particles radiation. The considered profiles are compared with observed ones. A good agreement was found with profiles of γ-pulsars — Geminga, Crab and Vela.

We present an analysis of the timing data of the pulsar B1642−03, collected over a span of 30 years between 1969 and 1999. During this interval, the timing residuals exhibit cyclical changes with amplitude varying from 15 ms to 80 ms and spacing of maxima varying from 3 years to 7 years. Interpretation of these observed cyclical changes in terms of free precession suggests a wobble angle of abo...

We investigate the development of electromagnetic cascades in ice using a GEANT Monte Carlo simulation. We examine the Cherenkov pulse that is generated by the charge excess that develops and propagates with the shower. This study is important for the RICE experiment at the South Pole, as well as any test beam experiment which seeks to measure coherent Cherenkov radiation from an electromagneti...
