#242 ΛCDM is alive and well
“ΛCDM is alive and well” arXiv:2205.05017 https://arxiv.org/abs/2205.05017
They say that so nobody will panic - this is common practice in dire situations. Cosmologists still hope there will be enough lifeboats…
P.S. Sorry, I can’t resist updating the meme.

Just like Elvis!
The paper seems to refute or at least show new tensions with most lcdm extensions. Lcdm is clearly dead via many independent probes and it’s only hope are its extensions so it doesn’t bode well. The title also reminds me of https://arxiv.org/abs/2310.03063
Conversely here’s a paper with a play on word saying to put LCDM in the bin (trashcan) https://arxiv.org/abs/2206.11447 Because it is no longer a model with constant integration constants.

From the picture: with z=28.5 the Big Boat has sunk completely.
