We report on the deep (100 ksec) XMM-Newton/EPIC observation of the field of the Geminga pulsar. The unprecedented throughput of the instrument allowed to detect two elongated para…
Prospects for High Energy Studies of Pulsars with the AGILE Gamma-Ray Telescope
A. Pellizzoni, A. Chen, M. Conti +4
AGILE is a small gamma-ray astronomy satellite, with good spatial resolution, excellent timing capabilities and an unprecedented large field of view (~1/5 of the sky). It will be t…
The X-ray sources at the center of G266.1-1.2
S. Mereghetti, A. Pellizzoni, A. De Luca
We present optical observations of the fields of two X-ray sources located near the center of the shell-like supernova remnant G266.1-1.2. No objects brighter than R~22.5 and B~23…
The Cosmological Evolution of BL Lacertae Objects
P. Giommi, A. Pellizzoni, M. Perri +1
We review the main results from several radio, X-ray and multi-frequency surveys on the topic of cosmological evolution of BL Lacertae objects. Updated findings on BL Lac evolution…
