Paso más tiempo desde que salió Tango 4 (García-Aznar) a hoy, que desde que salió Pet Sounds de The Beach Boys a Tango 4. Digo esto por el cover de God Only Knows (Sólo Dios sabe) que tiene Tango 4, que es increíble.
Solo eso digo. Nos vemos en un par de años más.

Extending the kudos to the TDCOSMO team, this stepped up confidence in their results. I am also really excited for the future, hopefully Vera Rubin Observatory's LSST will find more of these systems + new lensed SNIa, even in galaxy-scale lenses!

[Dan Scolnic @DScol]

Wow, big congrats to TDCOSMO for their `Milestone’ paper: https://t.co/RPATg36gYA . They analyze 8 strongly lensed quasars and find Hubble constant of 72+-3 km/s/Mpc with supernova prior on Omega_M, and H0=73+-3 with DESI BAO prior. This was one of the two local H0 studies from JWST I was most excited to see this year because the teams and tools are independent of SH0ES (other was the TRGB-SBF Project, got 73.8+-2.4). This was an amazing 6 year (!!) journey by TDCOSMO to get here..Story time..

The world's "First Look" at imagery from Rubin Observatory is coming in mid-2025 — and we want the whole world to join in the celebration! 🥳

Join the global excitement by signing up to host a #RubinWatchParty!

Scrub a dub 🫧 ...except no scrubbing the delicate observatory optics!

We don't use cloths or lens cleaner to clean the giant camera lenses. Instead, our summit staff use a high-speed stream of carbon dioxide "snow" to push debris off of the glass surface.

@NikoSarcevic It's 4 seasons a day, 12 seasons a year. NC climate.

[Mario Juric @mjuric]

Yes!!!

The first public image from @VRubinObs 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.

[Bruno Sánchez @BrunoSanchez63]

When working in a collaboration, in an environment with people from diverse backgrounds, neglecting their human side hurts everything. There's no way we can succeed on science, or in any other large or complex project, by dissecting part of the community, on any basis.

[Bruno Sánchez @BrunoSanchez63]

@NikoSarcevic That's just NC. You can have all four seasons in a day over there. And also, at the same time, NC has 12 seasons. Please search for the meme about it because it's hilarious.

NEW AAS Journal Author Series Video!

Bruno Sánchez (Aix Marseille University, @DukeU) chats with Frank Timmes about his article on supernovae: https://t.co/cMPjVCgdrF

The series connects authors w/their article, their human story & the larger #astronomy community. #TheGoodStuff

[Bruno Sánchez @BrunoSanchez63]

Thanks to @AAS_Office for the nice chat about some of the details on the DES SN 5YR data release paper!
It's a nice tour of the many pieces that make the release, with contributions from many people in DES-SN group!
Come hear about it at https://t.co/Ouu5ZwIEHy

We have a telescope!🤩

Last week, summit staff successfully installed Rubin Observatory's combined primary/tertiary mirror.

With all three mirrors & the commissioning camera in place, we officially—for the first time in 15 years of construction—have a complete telescope!🥳

@IralaDolores @StJudeResearch Amazing!! Todo lo mejor en esta nueva aventura!! :🎉 🎊

[Erik Peterson @erikpeterson23]

Just submitted a paper attempting to answer these questions: How many SN host galaxies are in galaxy groups? How much does accounting for galaxy groups improve Hubble residuals? Comments welcome! https://t.co/7j6RkKgGQF

[Dan Scolnic @DScol]

New paper by awesome @DukePhysics grad student Erik Peterson (@erikpeterson23) showing how we can improve measurements with the Hubble diagram at low-redshift by finding the 'groups' of galaxies that a supernova host galaxy is in 🧵https://t.co/Q8NZrpB9QP

Busy week - new paper by George Efstathiou pointing out potential systematic uncertainties in the DES-5yr supernova analysis and its constraints on evolving dark energy. I have some thoughts, but wanted to start with a genuine appreciation of George. https://t.co/Z5qf23Yx92
