Excited to share our new paper, in collaboration with @yuan_sihan & @CoraDvorkin ! Building upon our previous work, we obtain cosmological constraints from BOSS galaxy clustering using a simulation-based emulator of the wavelet scattering transform

Our new results are out! We have observed a single nuclear recoil in our detector that we find difficult to explain with our background model. Could it be a hint of dark matter? It’s far too early to say, but it’s certainly intriguing! #darkmatter

A great decade for astronomy begins with the Rubin Observatory @VRubinObs !

[NOIRLab @NOIRLabAstro]

This is it. The FIRST released video from @VRubinObs. A new era of astronomy starts now! ✨

How many galaxies do you think are in this image? 10 MILLION 🤯

Here, Rubin’s view is focused on the southern region of the Virgo Cluster.

Breaking news!🎉 Today we announce the most precise measurements of our expanding Universe using the BAO signal in 6.1 Million galaxies and quasars from Year 1, tracing dark energy through cosmic time. See @BerkeleyLab PR at https://t.co/3BZm4VQU9A 1/10

Last January, I noticed something peculiar in my 2yo’s bedroom that - after a year of obsessive reporting - led me to a profound cosmic revelation about what’s even possible in our universe. A 🧵.

[Simons Foundation @SimonsFdn]

News: After 15 years of carefully observing stars called #pulsars throughout our galaxy, the @NANOGrav collaboration has “heard” the perpetual chorus of #GravitationalWaves rippling through our universe. Read more about this groundbreaking discovery here: https://t.co/KSzPNXoA8v

[Georgios Valogiannis @GeorgiosGv89]

Excited and grateful to be part of the latest effort to efficiently simulate structure formation in Horndeski gravity theories! Summary in the thread below!

[Tessa Baker @Tessa_M_Baker]

World, meet Hi-COLA! Hi-COLA is the brand new code developed by @BillWrightCosmo @Cosmo_Canine @GeorgiosGv89 and myself, to simulate cosmological structure in weird and wonderful theories of gravity.
