Focusing Telescopes in Nuclear Astrophysics

Peter von Ballmoos est né en 1956 à Zürich. Après des études de physique à l'Ecole Polytechnique Fédérale de Zürich, un doctorat à l'Université Technique de Munich, et des post-docs outre Atlantique, il a été élu professeur d'astrophysique à l'Université de Toulouse en 1991.Au sein du Centre d'Etudes Spatiales des Rayonnements de Toulouse, il mène des recherches en astrophysique nucléaire - en particulier l'instrumentation, l'observation et l'interprétation des raies gamma nucléaires. L’observation des raies gamma nucléaires est une des clés aux questions fondamentales sur la structure et l'évolution de l'Univers, et particulièrement sur les cycles de vie de la matière et du comportement de la matière dans des conditions extrêmes. Peter von Ballmoos est co-responsable du projet Spectromètre INTEGRAL de l'ESA et responsable des projets "lentille gamma" du CNES (CLAIRE, MAX).
