The Institute of High Energy Physics (IHEP) held the third PANDA Symposium on Time Domain Astronomy and First Results from Insight-HXMT from June 18^th to 22^nd in Chengdu.

Nearly 150 attendees from scientific institutions and universities in China and over 30 from eight foreign countries participated in this symposium.

80 oral talks were delivered at the meeting, of which 26 were invited talks. The symposium was held right after one year of the launch of Insight-HXMT. The first initial scientific results from the Insight-HXMT were reported at the meeting.

Some hot topics in high-energy astrophysics were also discussed, including  the satellite’s instrument operation status and performance as well as scientific contributions interspersed in several scientific areas encompassing extreme astrophysical environments and the physical processes in the transient Universe, such as gravitational waves and their electromagnetic counterparts, Gamma-Ray Bursts, accretion on black holes and neutron stars, pulsars, magnetars, as well as Galactic Plane monitoring and surveying for high energy transients.

A good part of the meeting was dedicated to lively discussions fostering international multi-wavelength collaborations on new ideas and multi- mission projects.

The PANDA Symposia series aims at establishing and fostering collaborations among young postdoctoral fellows (0-6 years from graduation) from the Pacific/Asiatic scientific community with their peers across the globe. Besides enabling scientific mobility and networking, this symposium provides young researchers with a forum to exchange ideas on current and future projects.
