Prof. Shan,  Wenlei started his talk with a very interesting topic with “Noise, Be  Quiet”. He explained how to decrease the noise level was very important  for instrument people. All their purpose is to obtain the real signals  as much as possible. He introduced his main contributions for a couple  of detectors of ALMA and his continuous contributions in the South Pole  Astronomy.

Prof. Wu,  Xuefeng first briefly introduced some science topic related to South  Pole Astronomy. Then he explained the fireball models for gamma-ray  bursts in very details. Certainly how to determine the distance  precisely is playing a key role.  He showed us the details analysis  about a sample of those gamma-ray bursts.

Discussions  were very hot. Only 15mins leftover. Prof. Liu, Siming presented his  talks with very rich pictures of radio galaxies, SNR. He pointed to us  that the radiation and acceleration mechanics of  particles in high  energy, both radio and X-ray (as Prof  Ji, Li complemented ) were very  important to understand the physics behind. Li also gave a additional  remark about the key role of the spectroscopy.

In the last  couple of minus, Prof. Ji, Li gave a real science news about the flares  of the supermassive black hole of our Galaxy, SgrA*, a newly accepted  ApJ articles shown in astro-ph with ID 1209.6354. She said it was a  Chandra large XVP project with 3Ms. and the data would be ready in a  year. She is a key member for diffuse hot plasma surrounding this black  hole.
