Molecular Hydrogen MAGIE

H2 as a Major Agent in Galaxy Interactions and Evolution

Beschreibung

Spitzer space telescope spectroscopy reveal a new class of galaxies with enhanced molecular hydrogen (H2) line emission, but where star formation is strongly suppressed. This is in sharp contrast with what is observed in standard star forming galaxies. These sources are all in active phases of galaxy evolution (galaxy interactions, AGN feedback, gas accretion in galaxy clusters, etc.). Why is H2 present in violent phases of galaxy evolution? How is the H2 emission powered? Why is the H2 gas inefficient at forming stars? What can we learn from these ''H2 galaxies'' about galaxy formation? This thesis addresses these questions, and discuss the theoretical and observational perspectives of this work (in particular Herschel and JWST).

Autor

Impassioned by astrophysics and teaching, Pierre Guillard got his master of physics at University of Paris 11 at Orsay, France. After having passed the Agregation de Sciences Physiques in 2005, he did his PhD thesis work at the Institute of Spatial Astrophysics in Orsay, on the physics of the interstellar matter and the evolution of galaxies.
