Central Compact Objects in Supernova Remnants
Andrea De Luca
Central Compact Objects (CCOs) are a handful of soft X-ray sources located close to the centers of Supernova Remnants and supposed to be young, radio-quiet Isolated Neutron Stars (…
Unveiling the nature of RX J0002+6246 with XMM-Newton
P. Esposito, A. De Luca, A. Tiengo +3
The X-ray source RX J0002+6246 was discovered close to the supernova remnant CTB1 in a ROSAT observation performed in 1992. The source phenomenology (soft spectrum, apparent lack o…
Using GRO J1655-40 to test Swift/BAT as a monitor for bright hard X-ray sources
F. Senziani, G. Novara, A. De Luca +3
While waiting for new gamma-ray burst detections, the Burst Alert Telescope (BAT) on board Swift covers each day ~50% of the sky in the hard X-ray band (``Survey data''). The large…
HST multi-epoch imaging of the PSR B0540-69 system unveils a highly dynamic synchrotron nebula
A. De Luca, R. P. Mignani, P. A. Caraveo +1
PSR B0540-69 is the Crab twin in the Large Magellanic Cloud. Age, energetic and overall behaviour of the two pulsars are very similar. The same is true for the general appearance o…
Gutzwiller description of non-magnetic Mott insulators: a dimer lattice model
Michele Fabrizio
We introduce a novel extension of the Gutzwiller variational wavefunction able to deal with insulators that escape any mean-field like description, as for instance non-magnetic ins…
