Hidden by the Shell – A Pulsar Wind Nebula Emerges in Vela Junior
March 2026 A pulsar is a highly magnetised, rapidly-rotating neutron star resulting from the collapse of the progenitor star’s compact core during a supernova explosion. This strong magnetic field then induces an electric field…
PWN Abundance – HESS J1718–385
June 2007 Pulsar wind nebulae – PWNe – are amongst the most abundant sources of very high energy gamma rays in our Galaxy. Rotational energy of the neutron star is converted – by some…
HESS J1912+101 – Yet Another Pulsar Wind Nebula?
May 2007 The H.E.S.S. survey of the Galactic Plane (Aharonian et al. 2005, 2006) initially covered the range from –30 degr. to +30 degr. Galactic longitude. More recently, the survey region was extended to…
HESS J1640–465 – A Pulsar Wind Nebula?
March 2007 The gamma-ray source HESS J1640-465 (Fig. 1) was discovered during the survey of the Galactic plane; with a size of 0.045 degrees it is among the most compact sources in the survey,…
