On the nature of the radio quiet X-ray neutron star 1E 1207.4-5209
Biping Gong, G. F. Bignami
The strange timing property of X-ray pulsar 1E 1207.4-5209 can be explained by the hypothesis that it is a member of an ultra-compact binary system. This paper confronts the ultra-…
X-ray and optical coverage of 3EG J0616-3310 and 3EG J1249-8330
N. La Palombara, G. F. Bignami, P. Caraveo +4
The limited angular resolution of gamma-ray telescopes prevents the straight identification of the majority of the sources detected so far. This is particularly true for the low la…
Geminga: a tale of two tails, and much more
P. A. Caraveo, G. F. Bignami, A. De Luca +5
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…
1E1207.4-5209 - a Unique Object
G. F. Bignami, A. De Luca, P. A. Caraveo +3
The discovery of deep spectral features in the X-ray spectrum of 1E1207.4-5209 focussed the attention of the astronomical community on this radio-quiet NS, making it the most inten…
Out of the Chorus Line : What Makes 1E1207.4-5209 a Unique Object?
A. De Luca, P. A. Caraveo, S. Mereghetti +3
The discovery of deep spectral features in the X-ray spectrum of 1E1207.4-5209 has pushed this Isolated Neutron Star (INS) out of the chorus line, since no other INS has shown sign…
Discovery of X-ray cyclotron absorption lines measures the magnetic field of an isolated neutron star
G. F. Bignami, P. A. Caraveo, A. De Luca +1
Isolated neutron stars are higly magnetized, fast rotating end points of stellar evolution. They are now becoming directly observable through X-ray astronomy, owing to their high s…
