    • Discovery of a new soft gamma repeater: SGR J0418+5729 

      van der Horst, A.J.; Connaughton, V.; Kouveliotou, C.; Gogus, E.; Kaneko, Y.; Wachter, S.; Briggs, M.S.; Granot, J. (2010)
      On 2009 June 5, the Gamma-ray Burst Monitor (GBM) onboard the Fermi Gamma-ray Space Telescope triggered on two short and relatively dim bursts with spectral properties similar to soft gamma repeater (SGR) bursts. Independent ...
    • An infrared ring around the magnetar SGR 1900+14 

      Wachter, S.; Ramirez-Ruiz, E.; Dwarkadas, V.V.; Kouveliotou, C.; Granot, J.; Patel, S.K.; Figer, D. (2008)
    • Magnetar twists: Fermi/Gamma-Ray Burst Monitor detection of SGR J1550-5418 

      Kaneko, Y.; Gogus, E.; Kouveliotou, C.; Granot, J.; Ramirez-Ruiz, E.; van der Horst, A.J.; Watts, A.L.; Finger, M.H.; Gehrels, N.; Pe'er, A.; van der Klis, M.; von Kienlin, A.; Wachter, S.; Wilson-Hodge, C.A.; Woods, P.M. (2010)
      SGR J1550-5418 (previously known as AXP 1E 1547.0-5408 or PSR J1550-5418) went into three active bursting episodes in 2008 October and in 2009 January and March, emitting hundreds of typical soft gamma repeater bursts in ...
    • SGR J1550-5418 bursts detected with the Fermi Gamma-ray burst monitor during its most prolific activity. 

      van der Horst, A. J.; Kouveliotou, C.; Gorgone, N. M.; Kaneko, Y.; Baring, M. G.; Guiriec, S.; Gogus, E.; Granot, J.; Watts, A. L.; Lin, L.; Bhat, P.N.; Bissaldi, E.; Chaplin, V. L.; Finger, M. H.; Gehrels, N.; Gibby, M. H.; Giles, M. M.; Goldstein, A.; Gruber, D.; Harding, A. K.; Kaper, L.; von Kienlin, A.; van der Klis, M.; McBreen, S.; Mcenery, J.; Meegan, C. A.; Paciesas, W. S.; Pe'er, A.; Preece, R. D.; Ramirez-Ruiz, E.; Rau, A.; Wachter, S.; Wilson-Hodge, C.; Woods, P. M.; Wijers, R. A. M. J. (2012-04)
      We have performed detailed temporal and time-integrated spectral analysis of 286 bursts from SGR J1550-5418 detected with the Fermi Gamma-ray Burst Monitor (GBM) in 2009 January, resulting in the largest uniform sample of ...
