Wednesday colloquia

The API colloquia are weekly meetings where people give a 45 minute overview of their work. Afterwards there is time for discussion. At the end of each month the colloquia are jointly held with GRAPPA.

The contact person for the regular API colloquia is Selma de Mink.
The contact person for the joint GRAPPA/API colloquia is Jacco Vink.


Past colloquia

Master colloquium: The bursting behaviour of AX J1745.7-2901

Sjors Broersen — UvA

In this talk, the X-ray bursting behaviour of the faint, transient, X-ray binary AX J1745.6-2901 is reported. This dipping and eclipsing source was first observed in 1996 by Maeda and collaborators and has shown several periods of activity since then. We have screened all XMM Newton observations in which this source was in the field of view.
