@NASAWebb is new, but we can still learn a lot from @NASAHubble! Here is our @PlotAstro from A3827! First visualisation of distorting directions and their *direct* dependence on the input data. The plot also shows the unusual rotations of the parity vectors.

My research questions include: a) how much dark matter do we really need (less than we think!)? b) what astro-problems are efficiently solved by AI and which only waste resources in this way? c) how to set up a least model-dependent & efficient data eval compatible with a) & b)

@CERNCourier Dark Matter detective here, but from the other end of the cosmic scale. I am also quite skeptical about detections in the near future, after John Ellis gave a great talk on these prospects some time ago and he didn't see much coming out after a systematic investigation, either.

Happy belated birthday, you Cosmological Constant, whatever you are! This paper is one rare case in which Einstein wrote about cosmology and it's a great example of his pioneering thinking (he also introduces what will later be the Cosmo Principle here!)

Woooow! Big news if confirmed!! 🎉 I wish my former collaborator would have lived to see that!
Possible fast radio burst (FRB) associated with the recent LIGO event!! "CHIME/FRB source FRB 20250206A detected less than 1 minute after @LIGO merger S250206dm, with the probability of spatial coincidence is order 0.1% "

@astronat Indeed, it gets less magical the longer you are there. ;) Will Handley is great, so I guess we can expect a lot of interesting papers coming out in the near future! 🚀

@astronat 😊😊😊 Enjoy! For me, it looked like Harry-Potter-Town, magic around every corner. But it's also Dennis Sciama's university. So big history in cosmology there! Who will you be working with?

@miniapeur There is no one way that works for all problems, but if there is some summary statistics/limiting cases from data that the hyperparameters are sensitive to, you can exclude some values for not yielding the right summary/limits.
