Photons, molecules and life : A tribute to

Sydney Leach

Friday September 23   2022 1:30 PM Conference room at  Château of Meudon Observatory

LERMA and ISMO are jointly organizing an international scientific symposium in memory of Sydney Leach (1924-2019). This colloquium will be held at the  Observatory of Meudon on 23 September 2022 at 1 30 PM. It will address current issues and recent developments in Molecular Photophysics, spectroscopy and dynamics of excited molecules, synchrotron radiation, astrochemistry - scientific fields in which Sydney Leach played a leading role throughout his career.

To evoke all aspects of Sydney Leach's personality, the afternoon will end with a concert

Invited Speakers:

Séverine Boyé Péronne (ISMO):" Photoionization of astrophysically-relevant radicals with SOLEIL synchrotron: spectroscopy and quantitative aspects. "

 François Dulieu (LERMA  et l’Université de Cergy Pontoise): "Formation des manteaux moléculaires à la surface des grains de poussières interstellaires"

John Simons (Oxford University) and David Field (Aarhus University) : "Sydney Leach: snapshots of a life remembered"

Alain Omont (IAP) :" PAHs in the diffuse interstellar medium: photo-chemistry and DIBs"

Matin Schwell (LISA ) :"VUV spectroscopy of prebiotic molecules"

Anne Zehnacker-Rentien (ISMO) :"In the wake of molecular photophysics: a spectroscopic journey"

With the participation of:

Rayanne Dupuis, Héléna Gourzoulidou, Irina Leach, Pelléas Leach, Stéphane Leach  and Dan Tepfer in video.
