4 papers on arXiv today studying the tensions on H0 and S8: arxiv.org/abs/2102.12902, arxiv.org/abs/2102.12758, arxiv.org/abs/2102.12498, arxiv.org/abs/2102.12489. Looking forward to Euclid data to shed some new light on these tensions!

Going beyond 2-point statistics for weak lensing can provide a lot of useful information! arxiv.org/abs/2102.10177

Constraining cosmological parameters with the most recent cosmic shear analysis of the Kilo-Degree Survey (KiDS-1000), arxiv.org/abs/2007.15633. Find out more about how cosmologists are pushing the boundaries of knowledge on the current understanding of our Universe! #weaklensing

Cosmic shear is a category of weak lensing, weak lensing is a category of gravitational lensing, and a type of macro lensing. We're interested in cosmic weak macro gravitational lensing; but most people will also just use "shear" :)

Machine learning is promising and rapidly growing area of research for #weaklensing . The first paper that mentions that such methods could be important, that we can find, was in 1996 authors.library.caltech.edu/97373/2/961210… Can anyone find an early reference?

#weaklensing doesn’t just affect galaxy observations. Here is a recent paper looking at lensing of the Cosmic Microwave Background arxiv.org/abs/2101.12193

The 2020s astronomy data revolution is coming! SPHEREx, @VRubinObs @NASARoman, @SimonsObs, @ESA_Euclid, and @eROSITA_SRG will be imaging much of the sky. With modern data science tools, it will be a decade of discovery!

k-cut 3 x 2 point statistics to reduce sensitivity to small poorly modeled scales and forecasts for #Euclid. Let's find it out! 🤓🧐🤟 arxiv.org/abs/2012.04672

Deep learning to predict the non-linear behaviour at small scales arxiv.org/abs/2012.00240. These approaches could significantly reduce the computational needs in simulations for future weak lensing surveys

A new emulator for baryonic effects has appeared today on the arXiv: arxiv.org/abs/2011.15018. This kind of emulators will be crucial to extract the maximum amount of information from next-generation weak lensing surveys!
