Enabling Weak Lensing Cosmology

[Enabling Weak Lensing Cosmology @weaklensing]

4 papers on arXiv today studying the tensions on H0 and S8: https://t.co/UGOxQXxRGE, https://t.co/8XjRtW1ZML, https://t.co/TrWRqWsIrc, https://t.co/T2uIusKy0l. 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! https://t.co/KBOD0d7xUE

Your front-row seat to my Mars landing is here. Watch how we did it.

#CountdownToMars

[ARCHIVED - NASA's Perseverance Mars Rover @NASAPersevere]

Hello, world. My first look at my forever home. #CountdownToMars

[ARCHIVED - NASA's Perseverance Mars Rover @NASAPersevere]

It’s go time. The team is watching from Mission Control at @NASAJPL. Join LIVE for the final #CountdownToMars. Touchdown in just over 90 mins: https://t.co/4oCQB6bBcz

One step closer to exploring the Universe!

[ESA Science @esascience]

The @ESA_Euclid optical and infrared instruments are now fully integrated into the spacecraft!

This is an important step for #Euclid, which is scheduled for launch in 2022 to investigate dark matter, dark energy and the expanding Universe 🚀

Constraining cosmological parameters with the most recent cosmic shear analysis of the Kilo-Degree Survey (KiDS-1000), https://t.co/mmuXtLNje1. Find out more about how cosmologists are pushing the boundaries of knowledge on the current understanding of our Universe! #weaklensing

[Enabling Weak Lensing Cosmology @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 https://t.co/l40ZbrhI88 Can anyone find an early reference?

[Enabling Weak Lensing Cosmology @weaklensing]

#weaklensing doesn’t just affect galaxy observations. Here is a recent paper looking at lensing of the Cosmic Microwave Background https://t.co/iUwceaoQfA

[Enabling Weak Lensing Cosmology @weaklensing]

#weaklensing affects not just galaxy observations. Here a recent paper looking at lensing of 21cm emission https://t.co/m0eBiYrNOZ

The full DES data release is now available to everybody

[Fermilab @Fermilab]

The Dark Energy Survey has made public a catalog of nearly 700 million astronomical objects! The full data release is online and available to explore:

@theDESurvey @NCSAatIllinois @NOIRLabAstro #AAS237 #DESDR2

[Dark Energy Survey @theDESurvey]

Our full data release (data release 2), from all six years of observations is now public! Check out the link and thread for more details!

[David Spergel @DavidSpergel]

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!

[Enabling Weak Lensing Cosmology @weaklensing]

@ESA_Euclid launches next year! 🚀 prepare for your view of the cosmos to change 🌃🛰

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

Waiting for #Euclid... 👊

[ESA's Euclid mission @ESA_Euclid]

The #EuclidMission is designed to map Dark Matter (DM) with weak lensing. But it shall also discover more than 100,000 strongly lensed galaxies.
A recent study with #Hubble data suggests that there could be an ingredient missing from current DM theories.

Deep learning to predict the non-linear behaviour at small scales https://t.co/amNo8YZHF8. These approaches could significantly reduce the computational needs in simulations for future weak lensing surveys

[Enabling Weak Lensing Cosmology @weaklensing]

A new emulator for baryonic effects has appeared today on the arXiv: https://t.co/akRk1HY3sn. This kind of emulators will be crucial to extract the maximum amount of information from next-generation weak lensing surveys!
