Deuterated Species as Tracers of Star Formation

Le 7 février 2020 De 10h30 à 12h00 Laurent Pagani Observatoire de Paris In the ‘70s, while several groups were trying to measure various isotopic ratios in dark clouds (13C/12C, 18O/17O/16O,...), it was quickly realized that the D/H ratio of several molecules was...

Constraining feedback models with Giant Ly-alpha nebulae at z~3

Le 17 janvier 2020 De 10h30 à 12h00 Gabriele Pezzulli ETH Zurich   Galaxy formation models rely on mechanisms to keep the majority of baryons outside of the main body of galaxies. Different scenarios, however, make different predictions about where these "galactic missing...

The future is certain: Supernova Remnants in the multi-messenger era

Le 10 janvier 2020 De 10h30 à 12h00 Miroslav Filipovic Western Sydney University  This is an exciting time for the discovery and study of supernova remnants (SNRs), which reflect a major process in the elemental enrichment of the interstellar medium (ISM). The study of this...

Quenching star formation in massive galaxies

Le 20 décembre 2019 De 10h30 à 12h00 Allison Man University of Toronto  A fundamental question in galaxy evolution is how galaxies acquire diverse colours and morphologies. The current paradigm suggests that massive galaxies experienced accelerated growth in the early Universe...

Molecular gas and star formation in galaxy interactions

Le 6 décembre 2019 De 10h30 à 12h00 Ute Lisenfeld Universidad de Granada  Galaxy interaction can affect strongly the star formation activity and the molecular gas content of galaxies. Frequently, interaction enhances both quantities, but this is not always the case. I will...

Recents news from supernova remnants in X- and gamma-rays

Le 29 novembre 2019 De 10h30 à 12h00 Fabio Acero  CEA  The large amount of energy released in the supernova explosion leads to the creation of a fast shock wave which is an important source of cosmic-rays, kinetic and thermal energy in the interstellar medium. Supernovae are...

Gaia: a giant leap for astrophysics

Le 22 novembre 2019 De 10h30 à 12h00 Stefan Jordan  ARI Heidelberg  Since 2014, ESA's Gaia satellite measures the positions  of a huge number of stars of our Milky Way in order to gain a better understanding of the structure and evolution of our home galaxy.  In recent...
