The Twin Magnetars: SGR 1627-41 and 1E 1547-5408
S. Mereghetti, A. Tiengo, P. Esposito +10
We report on recent results obtained thanks to Target of Opportunity observations of the two galactic sources SGR 1627-41 and 1E 1547-5408. These two transient sources present seve…
Quiet but still bright: XMM-Newton observations of the soft gamma-ray repeater SGR 0526-66
A. Tiengo, P. Esposito, S. Mereghetti +6
SGR 0526-66 was the first soft gamma-ray repeater (SGR) from which a giant flare was detected in March 1979, suggesting the existence of magnetars, i.e. neutron stars powered by th…
Spin-down rate and inferred dipole magnetic field of the soft gamma-ray repeater SGR 1627-41
P. Esposito, M. Burgay, A. Possenti +11
Using Chandra data taken on 2008 June, we detected pulsations at 2.59439(4) s in the soft gamma-ray repeater SGR 1627-41. This is the second measurement of the source spin period a…
The Behavior of Matter under Extreme Conditions
F. Paerels, M. Mendez, M. Agueros +29
The cores of neutron stars harbor the highest matter densities known to occur in nature, up to several times the densities in atomic nuclei. Similarly, magnetic field strengths can…
Topology of magnetars external field. I. Axially symmetric fields
L. Pavan, R. Turolla, S. Zane +1
There is an increasing theoretical and observational evidence that the external magnetic field of magnetars may contain a toroidal component, likely of the same order of the poloid…
A statistical study of gamma-ray burst afterglows measured by the Swift Ultra-violet Optical Telescope
S. R. Oates, M. J. Page, P. Schady +14
We present the first statistical analysis of 27 UVOT optical/ultra-violet lightcurves of GRB afterglows. We have found, through analysis of the lightcurves in the observer's frame,…
