Pulsars

Main meetings/events from Aug. 2018 to Nov. 2018

Members of the SKA Pulsar Science Working Group (SKA-PSWG) and the various Pulsar Timing Array (PTA) consortia have attended the following meetings during this time period:

  1. IAU GA, Vienna: the Division D meeting discussed some of the SKA Key Science. PSWG members also attended the meeting on “Extragalactic Magnetic Fields.”
  2. LOFAR data school, Sept. 17-21, ASTRON. 50 participants from around the world were introduced to the data analysis for interferometric and beamformed data from LOFAR, which is one of the SKA pathfinders.
  3. NANOGrav Collaboration Meeting, Oct. 15-17, 2018, Green Bank Observatory. This is the semi-annual collaboration meeting for this PTA collaboration.
  4. “Astronomy Northwest by Southwest 2018”, Nov. 3-4, University of British Columbia. This was a gathering of astronomers from BC and the Northwestern US states.
  5. EPTA collaboration meeting, Nov. 12-14, Bielefeld, Germany.

Milestone related to pulsar and transient work: the Canadian Hydrogen Intensity Mapping Experiment (CHIME) was granted SKA pathfinder status.

Publications related to the PSWG from Aug. 2018 to Nov. 2018

During these months, the members of the PSWG and their collaborators have published and/or submitted to international refereed journals many papers dealing with research of interest for the SKA-PSWG. A selected listing of papers is below, with some additional entries from July that were not included in the previous e-News. In addition, the proceedings volume from IAUS 337, “Pulsar Astrophysics: the Next Fifty Years,” appeared during this timeframe.
