Hubble bubble

I wrote a poem once about God blowing bubbles as a take on creation and cosmology - not that I'm claiming anything or anything - so ... interesting

Question of the day: does somebody know a (recent) catalogue of galaxy groups and clusters in our local universe with redshift-independent distances, redshifts and member galaxy properties like vel-disps? (yes, we know cosmicflows but we are rather thinking of DESI or so)

Great news today! Wendy #Freedman has received the #NationalMedalOfScience at the White House. Cordial congratulations and I very much appreciate the work she has done to advance our understanding of late-universe #cosmology & #astrophysics.

A wonderful good morning to the #Astrodon community!
The #Cosmoverse COST action releases the videos of its last workshop one after the other. Here is one of the latest ones that is quite interesting:

Double-feature today! Who's interested in constraining the cosmological constant from the local universe?
If you happen to speak German, then this video is for you:

If not, here is a paper I co-authored that is a follow-up with more details and systematic tests for more two-body-systems:

🚨 Advance publication by Camila Franco, Felipe Avila, and Armando Bernui, in #MNRAS on probing isotropy in the Local Universe, using the Arecibo ALFALFA survey data: study finds a signature of the Dipole Repeller we discovered back in 2017. That's just great!
