Discovery of a New Soft Gamma Repeater , Sgr 1627 – 41
We report the discovery of a new soft gamma repeater (SGR), SGR 1627–41, and present BATSE observations of the burst emission and BeppoSAX NFI observations of the probable persistent Xray counterpart to this SGR. All but one burst spectrum are well fit by an optically thin thermal bremsstrahlung (OTTB) model with kT values between 25 and 35 keV. The spectrum of the X-ray counterpart, SAX J1635....
متن کاملSpin - down rate and inferred dipole magnetic field of the soft gamma - ray repeater SGR 1627 – 41
Using Chandra data taken on 2008 June, we detected pulsations at 2.594 39(4) s in the soft gamma-ray repeater SGR 1627–41. This is the second measurement of the source spin period and allows us to derive for the first time a long-term spin-down rate of (1.9 ± 0.4) × 10 s s. From this value we infer for SGR 1627–41 a characteristic age of ∼2.2 kyr, a spin-down luminosity of ∼4 × 10 erg s (one of...
متن کاملThe Type Ib/c Supernova, Gamma-Ray Burst, Soft Gamma-ray Repeater, Magnetar Connection
The polarization of core-collapse supernovae shows that many if not all of these explosions must be strongly bi-polar. The most obvious way to produce this axial symmetry is by the imposition of a jet as an intrinsic part of the explosion process. These jets could arise by MHD processes in the formation of pulsars and be especially strong in the case of magnetars. The jets will blow iron-peak m...
متن کاملXMM-Newton observations of the Soft Gamma Ray Repeater SGR 1627–41 in a low luminosity state
The sky region containing the soft gamma-ray repeater SGR 1627–41 has been observed three times with XMM-Newton in February and September 2004. SGR 1627–41 has been detected with an absorbed flux of ∼9×10 erg cm s (2-10 keV). For a distance of 11 kpc, this corresponds to a luminosity of ∼3×10 erg s, the smallest ever observed for a Soft Gamma Repeater and possibly related to the long period of ...
متن کاملXMM-Newton observation of the Soft Gamma Ray Repeater SGR 1627–41 in a low luminosity state
The sky region containing the soft gamma-ray repeater SGR 1627–41 and the hard X-ray transient IGR J16358–4726 has been observed with XMM-Newton in September 2004. SGR 1627–41 has been detected with an absorbed flux of ∼9×10 erg cm s (2-10 keV), slightly smaller than that seen with Chandra in 2001-2003. For a distance of 11 kpc, this corresponds to a luminosity of ∼3×10 erg s, the smallest ever...
