[en] The 2CG sources 218-00, 135+01, 121+04 and 95+04 have been observed at two radio frequencies and the flux values and spectra of the radio sources observed within the gamma-ray fields are catalogued down to a sensitivity of approx 30 mJy at lambda 11 cm. Possible gamma-ray counterpart candidate objects are briefly discussed

[en] Accumulated γ-ray evidence on the time variability of the pulse height ratio (PHR) of the Crab pulsar is shown to be compatible with a long-term (∼ 10.7 y) periodicity and can be interpreted as the free precession of the underlying neutron star. A prediction for the value of PHR by the coming GRO-EGRET γ-ray observations under the present model is presented

[en] High energy (E>35 MeV) gamma ray data of SAS-2 satellite has been used to compare the intensity distribution of gamma rays with that of neutral hydrogen (HI) density along the line of sight, at high galactic latitudes (/β/>30⁰). A model has been constructed where the observed gamma ray intensity has been assumed to be the bum of a galactic component proportional to the HI distribution plus an isotropic extra-galactic emission. The X²-test of the model parameters indicate that about 40% of the total high latitude emission may originate within the galaxy. (author)
