Research
- Analysis of INTEGRAL's Earth Observations
- This is my most recent research subject. It was a long lasting effort that
finally comes to an end...
- Outburst Modelling in Astrophysical Jets
- This is my main research field which I started during my PhD and continues
to offer very interesting development opportunities. It allows to study the
physics of energetic jets powered by super-massive black holes in blazars or by
solar mass black holes in microquasars located in our Galaxy. The link above
points to a full description of this work with nice animated images, links, etc.
I am now coordinating an international team that will meet in December at the
International Space Science Institut (ISSI) in Bern with the aim to develop both
theoretically and pratically the integration of the high-energy X-ray and
gamma-ray emission of blazar in the modelling (see the Team WWW page).
- Long-term multi-wavelength variability of 3C 273
- The bright quasar 3C 273 is my favourite source. During my PhD, we compiled
a large database of most multi-wavelength observations of 3C 273 since its
discovery more than 40 years ago. The publicly available database (linked above)
has been updated recently and contains more than 20'000 measurements in 70
lightcurves from the radio to the gamma-ray domain. The data have been used in
several publications on the multi-wavelength variability properties of 3C 273.
- Emission-line variability using Principal Component Analysis
- This is another research field started during my PhD. It uses the
mathematical tool called Principal Component Analysis (PCA) to decompose
emission-lines of active galactic nuclei (AGN) in two parts: the line profile
varying in tune with the underlying continuum and the line profile with
no or time-delayed variability.
