Introductory talks


Since this is a "hands-on" workshop with practical exercises, it is important that partipants bring their laptop computer.
Persons with an account at the Observatory/ISDC can use the tools (list below), which are installed on the Sun workstations and Linux PCs, and accessible via ugtools (virtualobs). For more instructions on their use see the Wiki.

Otherwise download/install the following tools on your machine and make sure they work before the day of the workshop. In case of trouble, contact Evanthia Hatziminaoglou (ehatzimi(at)

Other tools you might want to have a look at (but they will not be used during the tutorials):

For an exhaustive list of VO tools and services and their functionalities, have a look at the dedicated EURO-VO pages


User Case 0: Familiarise yourself with the tools User Case 1: Confirming a supernova candidate (uses Aladin, TOPCAT, SPLAT or VOSpec)

  • other things to try with Aladin:
  • look for available spectra in the field: one can look either for available spectra of a particular source s or make a larger search around the centre of the galaxy, encompassing the entire field covered by our image
  • User Case 2: Search for ULX sources and X-ray binaries in nearby (e.g. D<10 Mpc) galaxies (uses TOPCAT, Aladin)

    ULXs (Ultra-Luminous X-ray sources) are X-ray sources that are less luminous than AGN but more luminous than any known stellar process (Lx > 10^39 erg/sec)
