Beschreibungen/Notizen

• We report the discovery of 3.76 s pulsations from a new burst source near Sgr A[sup *] observed by the N mu STAR observatory. The strong signal from SGR J1745-29 presents a complex pulse profile modulated with pulsed fraction 27% + or - 3% in the 3-10 keV band. SGR J1745-29 joins a growing subclass of transient magnetars, indicating that many magnetars in quiescence remain undetected in the X-ray band or have been detected as high-B radio pulsars. The peculiar location of SGR J1745-29 has important implications for the formation and dynamics of neutron stars in the Galactic center region.
