Using the most powerful telescopes on Earth and in space, a team of astronomers has found for the first-time blasts of hot, warm and cold winds from a neutron star whilst it consumes matter from a nearby star. The discovery provides new insight into the behaviors of some of the most extreme...
An international team of astrophysicists, including researchers from the Observatoire astronomiquede Strasbourg, have detected six “merging galaxies” of our Milky Way – those small “foreign” galaxiesthat sequentially merged into the Milky Way during its long history of 12 billion years...
An international team of researchers including astrophysicists from the Observatoire astronomique de Strasbourg, the Observatoire de la Côte d’Azur, and the Observatoire de Paris discovered the remnants of a star cluster whose stars share a uniquely low fraction of heavy elements. As successive...
Using the European Southern Observatory’s Very Large Telescope (ESO’s VLT), a team of astronomers led by Karina Voggel (Strasbourg astronomical Observatory, CNES-CNRS) have revealed the closest pair of supermassive black holes to Earth ever observed. The two objects also have a much smaller...
In the last decades, radio astronomers have published a number of catalogues, listing astronomical radio sources detected in various frequency bands in different regions of the sky. The SPECFIND catalogue, whose first version was released in 2005 (Vollmer et al., 2005), is an attempt at combining...
In this first episode of the webseries "Lieux de sciences", Grand Labo takes us on a journey through astronomical observatories, including the one in Strasbourg. See it on YouTube...
Andromeda galaxy and Milky Way encounter becomes clearer thanks to latest Gaia data Will we see the Andromeda galaxy and the Milky Way merge in a few billion years? This is the question that the results of this study involving researchers from the Besançon and Strasbourg observatories will...
For her spectacular results on the chemical composition and dynamics of stars in the inner regions of our Milky Way, the Astronomische Gesellschaft (German Astronomical Society) awards the Doctoral Thesis Prize to Anke Arentsen. She received her PhD from the Leibniz Institute for Astrophysics...
For the first time, two young researchers from the Strasbourg Astronomical Observatory have created an artificial intelligence to estimate the properties of globular clusters observed in galaxies, including the Milky Way. Globular clusters are collections of tens of thousands to several million...
Pierre Ocvirk, de l’Observatoire astronomique de Strasbourg, vient de terminer les calculs de Cosmic Dawn III, une gigantesque simulation du premier milliard d’années de l’Univers, période qui comprend la naissance des toutes premières étoiles, marquant ainsi la fin de la période des...
