Career, milestones

  1. Current Position at European Space Agence (ESA) since December 2008.
    Science Operations for the Astrophysics missions XMM-Newton and INTEGRAL.
    Research Fellowship Coordinator
  2. 2008: Awarded of a Ramon y Cajal Fellowship for research in Physics and Astronomy in Spain.
    Out of over 200 applications, I have ranked 9th, but have chosen the current ESA position.

Spectral Time Map of XMM-Newton RGS spectrum of the Recurrent Nova V3890 Sgr (1962, 1990, 2019). The four panels share x/y axes as follows:

1) Top left: photon flux versus wavelength: Average spectrum (black line with blackbody approximation with red dotted line) and two spectra extracted from different time intervals (see below)

2) Top right: Colour code along photon flux axis used in:

3) Bottom left: Time (from top down) versus wavelength: Time resolved spectra, the colours correspond to photon fluxes as in top right panel. Horizontal dashed lines mark the time intervals over which the shaded spectra of same colour in the top left panel are integrated

4) Bottom right: Light curve turned around by 90 degrees with time along same axis as 3) and count rate horizontally. The shaded areas mark the time intervals over which the shaded spectra of same colour in the top left panel are integrated
