How rapidly do neutron stars spin at birth?
Roberto Soria, Rosalba Perna, David Pooley +1
We have studied the X-ray properties of ageing historical core-collapse supernovae in nearby galaxies, using archival data from Chandra, XMM-Newton and Swift. We found possible evi…
The short GRB070707 afterglow and its very faint host galaxy
S. Piranomonte, P. D'Avanzo, S. Covino +18
We present the results from an ESO/VLT campaign aimed at studying the afterglow properties of the short/hard gamma ray burst GRB 070707. Observations were carried out at ten differ…
X-ray flares and the duration of engine activity in gamma-ray bursts
Davide Lazzati, Rosalba Perna
The detection of bright X-ray flares superimposed on the regular afterglow decay in Swift gamma-ray bursts has triggered theoretical speculations on their origin. We study the temp…
Unveiling the multi-wavelength phenomenology of Anomalous X-ray Pulsars
GianLuca Israel, Luigi Stella, Stefano Covino +6
During 2002-2003 the number of IR-identified counterparts to the Anomalous X-ray Pulsars (AXPs) has grown to four (4U0142+614, 2E2259+584, 1E 1048-59 and 1RXS J170849-400910) out o…
A pulsar-atmosphere model for PSR 0656+14
D. A. Lloyd, R. Perna, P. Slane +2
We present a pulsar-atmosphere (PA) model for modulated thermal X-ray emission from cooling magnetized neutron stars. The model synthesizes the spectral properties of detailed stel…
