Friends. The Chandra Source Catalog version 2.1 has been released! This is a very rich and exciting dataset for astronomical discovery, and for data-driven exploration, regardless of whether you are an X-ray astronomer or not. Enjoy it! cxc.cfa.harvard.edu/csc/

💫 The world's largest digital camera for astronomy is complete. Once in place atop a telescope in Chile, the #LSST Camera will gather an unprecedented amount of data about our universe, yielding new insight into everything from asteroids to dark energy: stanford.io/3TH5VLk

Want some help digesting the new DESI Survey results? Watch @SeshNadathur and Andreu Font Ribera talk through it all in a Cosmology Talk... 🙂 youtu.be/9DsMphPfrjI

Astro friends, you can still send an abstract to the Latin American Conference on Astrophysics and Relativity, #LACAR2024, which will be held in Bogota, Colombia this June. We have a wonderful line-up of international speakers! See you in Bogota! lacar.webflow.io

🛠️ Hannah Pollek, SLAC mechanical engineer, gives us an inside look at how the LSST camera will photograph the southern night sky once it gets installed at NSF-DOE Rubin Observatory. stanford.io/3CTulcw #SLACExplains #RubinObservatory #capturethecosmos #Astronomy #DarkMatter #DarkEnergy

Great work led by Alex Broughton (UC Irvine)!

We just built at SLAC the largest digital camera in the world for astronomy, the LSSTCam! This paper presents a high-level explanation of the Instrument Signature Removal code that will be crucial for the LSST to revolutionize astronomy :) arxiv.org/abs/2404.14516

Last week, researchers at KIPAC and SLAC bid farewell to the world's largest digital camera, as it begins its journey to the NSF-DOE Rubin Observatory in Chile!

Rubin Observatory's 8.4-meter mirror is finally, well, a mirror! 🥳 The glass got its shiny coating this past weekend—but what did that actually look like? Find out in the fifth and final video in our "Making of Rubin's 8.4-meter Mirror" series ✨ #CaptureTheCosmos

Five million people have clicked on the Veritasium video on black holes featuring @Cosmic_Horizons and seen some Penrose diagrams, so I thought it would be a good time to explain what they are. I'll do this over a few days using the hashtag #penrosediagram.

La comunidad de #Astronomia de #Colombia se solidariza con nuestra colega y amiga Lauren Flor Torres Instamos a las autoridades de la Universidad de Antioquia a que tomen todas las medidas necesarias para poner fin a esta situación y garantizar su integridad personal de nuestra colega

I am retiring from teaching GR. Here is the final course material (lecture notes including all problem sets and exams). Hope some students might find it useful in their studies. tinyurl.com/5n786bkn [Thanks to Giovanni Maria Tomaselli for his amazing help in making the exam questions.]

Yes!!! The first public image from NSF-DOE Rubin Observatory Simonyi Survey Telescope (just the fun pixels 😉). Now ponder getting 21x this, every ~40 seconds, ~8hrs/night, for 10 years. That's what's coming by the end of this year.
