* NICER begins science operations


NASA’s Neutron Star Interior Composition Explorer (NICER) mission has been installed on the International Space Station and has now commenced science operations. As of July 17, NICER had observed over 40 celestial targets, which have been used to calibrate the X-ray timing instrument and validate the payload performance.


More general information on NICER:




* HXMT launch


China’s Hard X-ray Modulation Telescope (HXMT) launched successfully in mid-June and has been re-named Huiyan (Insight). Congratulations to everyone involved!




* IAU Symposium 342 – Perseus in Sicily


The organizers are pleased to announce the dates and location for the IAU Symposium #342 "Perseus in Sicily: from black hole to cluster outskirts".


The symposium will take place in Noto (Sicily) on 14-18 May 2018. Please mark your calendar!


Preliminary information is available at the website Detailed instructions with important dates, procedures for IAU Travel grant application, and logistic information will be circulated around mid-September.


Key topics include:


- approaching the Schwarzschild radius: methods to measure BH mass and spin

- BH magnetosphere & sphere of gravitational influence

- hot vs cold accretion

- magneto-hydrodynamical processes in disks and jets

- jet production, collimation, and acceleration mechanisms

- HE emission: site and mechanisms, particle acceleration, leptonic vs hadronic processes

- jet-medium interaction on galactic and cluster scales

- thermal and non-thermal emission in galaxy clusters

- turbulence, gas heating and cooling

- AGN winds and BH-galaxy coevolution


IAU Division D is the Coordinating Division for this Symposium. We hope that many of our members are able to attend!
