Pulsars: gamma-ray detected or not ? |
by Simon Johnston (CASS) |
Rookyard et al. have
explored why some high energy pulsars emit gamma-rays while others do not.
The figure shows the spin-down energy of a radio pulsar versus the width
of the pulse profile. The solid points are those detected in gamma-rays,
whereas the open points are not gamma-ray emitters. The authors conclude
that the geometry of the pulsar is the key to whether or not we see
gamma-ray emission (see figure) The paper has been accepted by MNRAS. |
