A new explanation for the SFXTs outbursts
L. Sidoli, P. Romano, S. Mereghetti +4
The physical mechanism responsible for the short outbursts in a recently recognized class of High Mass X-ray Binaries, the Supergiant Fast X-ray Transients (SFXTs), is still unknow…
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…
The first Suzaku observation of SGR 1806-20
P. Esposito, A. Tiengo, S. Zane +5
The soft gamma-ray repeater SGR 1806-20 has been attracting a lot of attention owing to the fact that in December 2004 it emitted the most powerful giant flare ever observed. Here…
The Peculiar Type Ib Supernova 2006jc: A WCO Wolf-Rayet Star Explosion
N. Tominaga, M. Limongi, T. Suzuki +21
We present a theoretical model for Type Ib supernova (SN) 2006jc. We calculate the evolution of the progenitor star, hydrodynamics and nucleosynthesis of the SN explosion, and the…
VLT observations of Compact Central Objects
R. P. Mignani, S. Zaggia, D. Dobrzycka +4
We present the first results of our VLT observation campaign of the Central Compact Objects (CCOs) in SNRs RX J085201.4-461753 (Vela Jr), 1E 1648-5051 (RCW 103) and RX J171328.4-39…
SGR 1806-20 about two years after the giant flare: Suzaku, XMM-Newton and INTEGRAL observations
P. Esposito, S. Mereghetti, A. Tiengo +9
In December 2004, the soft gamma-ray repeater SGR 1806-20 emitted the most powerful giant flare ever observed. This probably involved a large-scale rearrangement of the magnetosphe…
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…
Long term hard X-ray variability of the anomalous X-ray pulsar 1RXS J170849.0-400910 discovered with INTEGRAL
D. Gotz, N. Rea, G. L. Israel +6
We report on a multi-band high-energy observing campaign aimed at studying the long term spectral variability of the Anomalous X-ray Pulsar (AXP) 1RXS J170849.0-400910, one of the…
Precision photometric redshift calibration for galaxy-galaxy weak lensing
R. Mandelbaum, U. Seljak, C. M. Hirata +26
Accurate photometric redshifts are among the key requirements for precision weak lensing measurements. Both the large size of the Sloan Digital Sky Survey (SDSS) and the existence…
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…
Swift/XRT monitoring of five orbital cycles of LSI +61 303
P. Esposito, P. A. Caraveo, A. Pellizzoni +3
LSI +61 303 is one of the most interesting high-mass X-ray binaries owing to its spatially resolved radio emission and its TeV emission, generally attributed to non-thermal particl…
Dust-scattered X-ray halos around two Swift gamma-ray bursts: GRB 061019 and GRB 070129
G. Vianello, A. Tiengo, S. Mereghetti
Two new expanding X-ray rings were detected by the Swift XRT instrument during early follow-up observations of GRB 061019 and GRB 070129, increasing to 5 the number of dust scatter…
VLT observations of the Central Compact Object in the Vela Jr. supernova remnant
R. P. Mignani, A. De Luca, S. Zaggia +4
X-ray observations have unveiled the existence of enigmatic point-like sources at the center of young (a few kyrs) supernova remnants. These sources, known as Central Compact Objec…
XMM-Newton observation of the persistent Be/neutron-star system X Persei at a high-luminosity level
N. La Palombara, S. Mereghetti
We report on the XMM-Newton observation of the HMXRB X Persei, the prototype of the persistent and low-luminosity Be/neutron star pulsars, which was performed on February 2003. The…
Phase resolved spectroscopy of the Vela pulsar with XMM-Newton
A. Manzali, A. De Luca, P. A. Caraveo
The ~10^4 y old Vela Pulsar represents the bridge between the young Crab-like and the middle-aged rotation powered pulsars. Its multiwavelength behaviour is due to the superpositio…
VLT/NACO observations of the High-Magnetic field radio pulsar PSR J1119-6127
R. P. Mignani, R. Perna, N. Rea +3
Recent radio observations have unveiled the existence of a number of radio pulsars with spin-down derived magnetic fields in the magnetar range. However, their observational proper…
XMMU J174716.1-281048: a "quasi-persistent" very faint X-ray transient?
M. Del Santo, L. Sidoli, S. Mereghetti +3
The X-ray transient XMMU J174716.1-281048 was serendipitously discovered with XMM-Newton in 2003. It lies about 0.9 degrees off the Galactic Centre and its spectrum shows a high ab…
