XMM-Newton discovery of 2.6 s pulsations in the soft gamma-ray repeater SGR 1627-41
P. Esposito, A. Tiengo, S. Mereghetti +6
After nearly a decade of quiescence, the soft gamma-ray repeater SGR 1627-41 reactivated on 2008 May 28 with a bursting episode followed by a slowly decaying enhancement of its per…
On the evolution of the Gamma- and X-ray luminosities of Pulsar Wind Nebulae
Fabio Mattana, Maurizio Falanga, Diego Götz +7
Pulsar wind nebulae are a prominent class of very high energy (E > 0.1 TeV) Galactic sources. Their Gamma-ray spectra are interpreted as due to inverse Compton scattering of ultrar…
AGILE detection of delayed gamma-ray emission from GRB 080514B
A. Giuliani, S. Mereghetti, F. Fornari +55
GRB 080514B is the first gamma ray burst (GRB), since the time of EGRET, for which individual photons of energy above several tens of MeV have been detected with a pair-conversion…
The 2008 May burst activation of SGR 1627-41
P. Esposito, G. L. Israel, S. Zane +16
In May 2008 the soft gamma-ray repeater SGR 1627-41 resumed its bursting activity after nearly a decade of quiescence. After detection of a bright burst, Swift pointed its X-ray te…
XMM-Newton observations of CXOU J010043.1-721134: the first deep look at the soft X-ray emission of a magnetar
A. Tiengo, P. Esposito, S. Mereghetti
We present the analysis of six XMM-Newton observations of the Anomalous X-ray Pulsar CXOU J010043.1-721134, the magnetar candidate characterized by the lowest interstellar absorpti…
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…
