Numerical simulators are fundamental tools for the design and optimisation of missions and instruments.

I am and I've been involved in the development of different simulators, some of them are now publicly available.

Generic instrument simulators

The Generic instrument independent point source simulator. It's been used to build the radiometric models in the following missions: ARIEL, EXCITE, Twinkle, Mauve.

ExoSim 2

Refactored version of the end-to-end time domain simulator for the exoplanet transit observations.

Mission dedicated tools


Radiometric model simulator for the ARIEL space mission.


Wrapper of ArielRad and TauREx to produce ARIEL simulated data-set of entire planetary populations.

Other tools

Rosseland and Planck opacity converter. It produces the two mean opacities from data.
