Le rayonnement thermique en astrophysique [PDF]
Photoniques, 2020 Le rayonnement thermique est une source décisive d’informations pour une science de l’observation comme l’astrophysique. Dominant dans l’infrarouge lointain, il est difficile à mesurer, et nécessite le développement de détecteurs innovants et de techniques cryogéniques de pointe. Mise en œuvre à bord de satellite depuis 40 ans, la mesure du rayonnement

Study of the applicability of the curlometer technique with the four Cluster spacecraft in regions close to Earth [PDF]
Annales Geophysicae, 2012 Knowledge of the inner magnetospheric current system (intensity, boundaries, evolution) is one of the key elements for the understanding of the whole magnetospheric current system. In particular, the calculation of the current density and the study of
