i hate the world of #streaming.
i love the show #DarkMatter (the one from 2014/2015) but i can only buy seasons 2 and 3 on prime video.
i’ve finished season 3 and want to go back and rewatch, but the only place i can see season 1 is on appletv
that’s annoying, imo.
i know, first world problems, but fml

These results raise the question where we can track down dark matter? What do we know in the least model-dependent way?
For strong lensing, the question has an answer, look at this video for a recent summary:

2) the Bullet cluster is a more complicated structure than a binary system of two big dark-matter clumps that are offset to the baryons:
arxiv.org/abs/2503.21870
Masses were reduced and bounds on SIDM were set. Looks like we need less dark matter if the structure is more complex!
...and there is also a method to constrain dark matter properties purely from the multiple images, see this NASA press release for more:

Today was progress-day for lensing!
1) A1689 at z=0.183 is elongated along the line of sight:
arxiv.org/abs/2503.22316
I hope there will be studies of A3827, too. The latter is only at z=0.1 and it seems that the thickness also affects the strong lensing effects:

Foggy start to the day at UCLA this morning for the biennial UCLA Dark Matter Symposium, the largest dark matter conference in the world, which started in 1994, under lead organization by Prof. David Cline.
My first attendance of the series was as a graduate student in 1998, where the two groups detecting the acceleration of the Universe first reported their results. #cosmology #darkmatter #particlephysics #physics #astronomy

“Well, maybe it’s oligons.”
Great. Wolfram has an idea about what #DarkMatter is. It’s unobservable too. Of course it is.

Scientist Stephen Wolfram opens up his ongoing Wolfram Physics Project to a global effort. His team will livestream work in progress, post working materials, release software tools and hold educational programs.

[Zoom on the #CosmicWeb] Have you dived into the deep fields of #Euclid revealed this Wednesday by the @ec_euclid ? Have you navigated between the thousands of #galaxies of different shapes, sizes, colors and masses? So many objects, near and far, fill our #Universe! https://sky.esa.int/esasky/?hide_welcome=true&hide_banner_info=true&hips=DES-DR2+ColorIRG&sci=false&layout=esasky&euclid_image=EDFS
What if their spatial distribution could tell us something about two mysterious components : #DarkMatter and #DarkEnergy? This is the gamble taken by the scientists involved in the Euclid mission. To do so, they've designed some unrivalled #instruments: a camera with great depth of field and high resolution records the variety of shapes and spatial distribution of galaxies, while a #spectrometer coupled with a #photometer can determine the distances and masses of galaxies ...

We are particularly interested in contributions that show how and with which “tools” we can contribute to moving towards an inclusive future that may still be utopia today.

The article doesn’t say too much, but is it surprising to find the universe may be more complicated than we currently think it is?

On 19 March 2025, the European Space Agency’s Euclid mission released its first batch of survey data, including a preview of its deep fields. Here, hundreds of thousands of galaxies in different shapes and sizes take centre stage and show a glimpse of their large-scale organisation in the cosmic web.
