Pre-up

For the lectures, you need to bring your laptop with you and have already installed Xspec and DS9. Please do it as soon as possible, because the download and the installation may take time.

* For Xspec, you may download heasoft here: http://heasarc.gsfc.nasa.gov/lheasoft/download.html

  1. Step 1: select “Source code” and then your favorite platform.
  2. Step 2: select “all”. Click “Submit”.

* For DS9, you can download the software from this link: http://ds9.si.edu/site/Download.html

 (For Ubuntu users, you may find DS9 in Ubuntu Application Store.)

* SAS (software for data reduction of XMM-Newton observations) and Ciao (for Chandra) may also be necessary.

 (Ubuntu users (Ubuntu14.0) or Mac users may contact with current group member to retrieve already available installation packages.)

* Interested students, who intend to join our gravity group, may have access to our computer cluster by sharing the same group account and may not have to download packages/softwares mentioned above. However we do not guarantee perfect Internet connection to our cluster during the lectures. An ideal connection to the cluster is through Ethernet inside student residence.

Q&A

Prof Bambi and mini J. are both available through email. Just feel free to email either of us when you meet any problem.

* Prof Cosimo Bambi bambi@fudan.edu.cn

* Jiachen Jiang jcjiang12@fudan.edu.cn

Others The oral test will be entirely in English.

Mid term test Questions: 1) What are the apparent magnitude and the absolute magnitude of a star? 2) What can you say about the Hertzsprung–Russell diagram? 3) What is the Eddington Luminosity? 4) Describe the typical outburst of a black hole in an X-ray binary. 5) Describe one or more techniques to measure the spin of a black hole. 6) What can you say about gravitational waves?

**Upcoming** Visit of Dr Matteo Guainazzi
