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…

Discovery of extended X-ray emission around the highly magnetic RRAT J1819-1458

N. Rea, M. A. McLaughlin, B. M. Gaensler +7

We report on the discovery of extended X-ray emission around the high magnetic field Rotating Radio Transient J1819-1458. Using a 30ks Chandra ACIS-S observation, we found signific…

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…

Rise and fall of the X-ray flash 080330: an off-axis jet?

C. Guidorzi, C. Clemens, S. Kobayashi +31

X-ray flashes (XRFs) are a class of gamma-ray bursts (GRBs) with the peak energy of the time-integrated spectrum, Ep, below 30 keV, whereas classical GRBs have Ep of a few hundreds…

Suzaku observation of the Phoenix Galaxy

G. Matt, S. Bianchi, H. Awaki +5

In recent years, several Seyfert 2 galaxies have been discovered that change state when observed in X-rays a few years apart, switching from Compton-thin to reflection-dominated or…
