March 2013: Our two-part all-Alberta analysis of Galactic ultracompact X-ray binaries is accepted for publication in ApJ, "Galactic Ultracompact X-ray Binaries: Empirical Luminosities", by Cartwright, Engel, Heinke, Sivakoff, Berger, Gladstone, & Ivanova (Hans Berger's first paper), and "Galactic Ultracompact X-ray Binaries: Disk Stability and Evolution", by Heinke, Ivanova, Engel, Pavlovskii, Sivakoff, Cartwright, & Gladstone. See also Arash's first Astronomer's Telegram, "Confirmation of GRS 1747-312 as the active transient in Terzan 6".
March 2013: Jeanette's detailed analysis of the 33 nearest ULXs with Hubble and Chandra data is accepted for publication in ApJ Supplement, Optical counterparts of the nearest ultraluminous X-ray sources.

September 2012: Craig is awarded the Martha Cook Piper Research Prize (U of A 2012 Awards), recognizing annually two early-career U of A faculty members who show outstanding promise as researchers and enjoy a reputation for original research.
August 2012: Khaled Elshamouty successfully defends his master's thesis, "The Cooling of the Neutron Star in the Cassiopeia A Supernova Remnant". Congrats!
August 2012: Sonia Budac and Craig are coauthors on a paper studying X-ray binaries in the globular cluster NGC 6388 that has been accepted to ApJ, X-ray Binaries in the Ultrahigh Encounter Rate Globular Cluster NGC 6388.
