Do you wonder how looks like the orbits of MW dwarf galaxies in presence of a massive LMC perturbing the MW? Here is your answer: youtu.be/rSXFf5elcgM Also check our webpage of the systemic proper motions of Local Group galaxies: research.iac.es/proyecto/GaiaD…

Quelques clichés obtenus depuis les télescopes de l'Observatoire astronomique de Strasbourg durant l'éclipse partielle de soleil du 25/10/2022, avec @jds_unistra . Malgré quelques passages de nuages, les conditions d'observation étaient très bonnes !

Gaia's exquisite data allows to test existing theories as well! Do observations match with the current theories? Are Einstein and Newton wrong after all? More info here: cosmos.esa.int/web/gaia/iow_2… Image credit: Koupra, Jerabkova, et al.

Le dernier article de @kmalhan07, @nfmartin1980, @benfamaey et leurs collaborateurs lève un coin du voile sur l'histoire de formation de la Voie Lactée en identifiant six fusions massives de galaxies avec la nôtre depuis 12 milliards d'années. iopscience.iop.org/article/10.384…

And, on the same topic, @Thomas_gft & @gemrbattaglia recently independently mapped Cetus using data from spectroscopic data combined with artificial neural nets to infer the distance of Milky Way halo stars. (6/6) arxiv.org/abs/2112.03973

🔔🥁The new systemic proper motions of Local Group galaxies has arrived: arxiv.org/abs/2106.08819 Thank you @ESAGaia for those wonderful data

I am super excited to announce that we will discuss of the "Holistic view of the Milky Way: Linking ages, chemistry and kinematics" during a 2 days symposium (S1) at the next @EAS_meeting: eas.unige.ch/EAS2021/sessio…

A great thank to the team of the CFHT for this nice press release on our discovery of the M92 stellar stream with the data from the Canada-France-Imaging-Survey. Surprisingly, the progenitor is named after Charles Messier, who was Lorrain as well 😄 cfht.hawaii.edu/en/news/CFISM9…

Exciting Science News! Guillaume Thomas and a team of astronomers used data from the Canada-France Imaging Survey (CFIS) to discover a new stellar stream emanating from the globular cluster M92. cfht.hawaii.edu/en/news/CFISM9… #sciencenews #M92 #galacticcannibalism

Today, with found a new stellar stream emanating from the M92 cluster:arxiv.org/abs/2009.04487 A great thanks to the team of @CFHTelescope, @PanSTARRS1 and @ESAGaia for their amazing work to provide us these amazing dataset

I'm ridiculously excited that @Thomas_gft has submitted his latest paper, building on work we started together during his Master, %$& years ago! arxiv.org/abs/2009.00010

Neat paper from @Thomas_gft et al. who have created mocks of the PAndAS survey! arxiv.org/abs/2009.00010

@NushkiaC @IAC_Astrofisica Thank you very much @NushkiaC. So far I found the weather, even in La Laguna, lovely.

Very happy to start a new chapter of my life in Spain by starting as a Juan de la Cierva fellow at the @IAC_Astrofisica. Though the names are pretty similar, Canada and the Canaries islands have very different weather 😀

Joyeux 14 Juillet, version astronomique #France #14Juillet2020 #astronomy #Astronogeek

@8minutesold Congrats to her :D

My wife successfully defended her PhD in German Literature today. 👩‍🎓 I could not be more proud of her. 😊

@kmalhan07 I definitely going to use it in my next talk ;)

New mechanism for the formation of gaps in "accreted stellar streams" (Section 4.2 of arxiv.org/abs/2005.12919) -- presented as a video-graphic tour youtube.com/watch?v=_nhO_h…. There is a lot more detailed in the paper.
