| During the last week the observing schedule was replanned to include a
40 Ks observation of the source SGR 0501+4516 that was accepted as a fast turn-around Target Of Opportunity (TOO) on Aug 22. Loads were replanned and uplinked on Aug 23. Observations of SDSS J0148+0001, XTE J1701-407 and Abell 2187 were impacted by the TOO and will be rescheduled in a later load.
A Chandra image release was issued on Aug 27 of the galaxy cluster MACS J0025.4-1222. Like the Bullet Cluster this cluster shows a clear separation between dark and ordinary matter. This helps answer a crucial question about whether dark matter interacts with itself in ways other than via gravitational forces. For details see: http://chandra.harvard.edu/photo/2008/macs/ The schedule of targets for the next week is shown below and includes an observation M31 coordinated with HST. |
