This project focuses on the problem of measuring the BH spin.
There are three ways to measure BH spins; one is based on timing, and two are based on spectroscopic measurements in the X-ray band.
Both spectroscopic methods depend crucially on properly modelling the underlying continuum emission.
For this project, the PhD student will systematically analyze high-resolution X-ray spectra of a group of galactic and extragalactic BHs, taken with the Chandra and XMM-Newton observatories, accounting for the presence of this ionized absorber, and assessing how this gas affects the inferred BH spin.
Applications should be sent either by email or regular mail to the address below, and should include a curriculum vitae with a list of grades, a short (about 1-page long) summary of research interests and experience, and a short (about 1-page long) description of any previous research work (e.g., Bachelor and/or Master thesis), explaining the part carried out by the applicant, and the relevance of the work in a larger context.
The applicant must arrange for two reference letters being sent separately to the same address.
If English is not the native language of the applicant, the reference letters should include an assessment of the English level (written and oral) of the applicant.
