Since my #Waiting4WinterSolstice didn't go well with astro talks, how about some pictures of chocolate Santas and Rudolphs?

#Waiting4WinterSolstice -- last part (as the visibility and reactions to this thread series was super low): go to the @jrdmb.bsky.social database and enjoy a talk a day! 😁

#Waiting4WinterSolstice part 4 -- hopefully today's talk by @eu-phil-cosmo.bsky.social will draw some more likes, as it's tackling the question what we call "the missing mass" in astrophysics. Some say it's #DarkMatter, others call it #ModifiedGravity. Enjoy: youtu.be/2TBiTXqgczY?...

#Waiting4WinterSolstice Part 3! Today I want to share another #astro #scicomm talk I liked very much, this time about how to constrain the #CosmologicalConstant from #LocalGroup dynamics. Enjoy: youtu.be/Kt3bCFxhxLo?...

#Waiting4WinterSolstice Part2 today with an #outreach talk @TEDTalks about the highly intriguing question how we create galaxies in simulations: youtu.be/BmPTMYUqgg8?...

#Waiting4WinterSolstice Part1 -- an astro-talk a day about the dark side of the universe until Earth is brightening again!
Let's start with what we actually know about #DarkMatter in our universe from strong lensing and what models add to this picture.
