Scientific paper

A new magnetar candidate, PSR J1622-4950, has been discovered in the radio band by the Parkes High Time Resolution Universe (HiTRUn) Survey, presenting the typical erratic radio flux behaviour shown only by the two transient radio magnetars known thus far, and a magnetic field of 2x10^{14}G. Pulsed radio emission from magnetars have been so far always connected to transient X-ray outbursts. A prompt Chandra observation pinpointed positionally the X-ray counterpart to this new radio magnetar, which, however, did not show any flux increase with respect to archival X-ray observations. We aks for a 70ks XMM, observation of the recently discovered X-ray counterpart to PSR J1622-4950 in order to study its spectrum and search for X-ray pulsations.
