The Large Observatory For x-ray Timing

8 septembre 2014

The Large Observatory For x-ray Timing (LOFT) was studied within ESA M3 Cosmic Vision framework and participated in the final down-selection for a launch slot in 2022-2024. Thanks to the unprecedented combination of effective area and spectral resolution of its main instrument, LOFT will study (...)

The Large Area Detector of LOFT: the Large Observatory for X-ray Timing

8 septembre 2014

LOFT (Large Observatory for X-ray Timing) is one of the five candidates that were considered by ESA as an M3 mission (with launch in 2022-2024) and has been studied during an extensive assessment phase. It is specifically designed to perform fast X-ray timing and probe the status of the matter (...)

The SIRIUS Mixed analog-digital ASIC developed for the LOFT LAD and WFM instruments

23 juin 2014

We report on the development and characterization of the low-noise, low power, mixed analog-digital SIRIUS ASICs for both the LAD and WFM X-ray instruments of LOFT. The ASICs we developed are reading out large area silicon drift detectors (SDD). Stringent requirements in terms of noise (ENC of (...)

Modeling IR spectra of CO2 isotopologues and CH4 trapped In type I clathrate

21 février 2014

To test the hypothesis of atmospheric carbon dioxide or methane storage in metastable clathrate, a theoretical formalism is developed to model and simulate the spectra of the CO2 or CH4 molecule trapped in clathrates. 12-6 Lennard-Jones atom- atom potentials are used to account for short and (...)
