That's only if you consider the supernovae data alone. In combination with other probes like BAO, etc, the combined data are pointing to a Universe with a dynamical (or time varying) dark energy model.

It could be a big discovery and it also aligns with the findings from DESI BAO [1] and by another Korean group using galaxy clustering to infer the expansion history [2].

Its not publicly available. Maybe for the best haha. The speaker at some point went on a bit of a tirade against many people in the supernovae cosmology community. I think he endured many years of being ignored or belittled.

I know the team that did this. In fact i was listening to their seminar just a few days ago. They are very careful and have been working on this a long time. One caveat that they readily admit is that the sample used to create the luminosity age relation has some biases such as galaxy type and relatively lower redshift. They will be updating their results with the Rubin LSST data in the next few years.

Exciting times in cosmology after decades of a standard LCDM model.

Irgun and Etzel are different names for the same organization. https://en.wikipedia.org/wiki/Irgun

"Hannah Arendt and Albert Einstein, in a letter to The New York Times in 1948, compared Irgun and its successor Herut party to "Nazi and Fascist parties" and described it as a "terrorist, right wing, chauvinist organization" "

I just tested, indeed very good results!

In this work and in their previous papers they suggest that the dimming of distant supernovae can be at least partially explained by the age of the supernovae progenitor rather than cosmic acceleration. Their work now seems to agree much more with findings from DESI BAO + CMB, which suggest a much more complicated dark energy than simple vacuum energy. In this new analysis, the expansion of our universe could be actually decelerating at current times.

Israeli soldiers sexually abuse a Palestinian prisoner, while the leaker gets hounded. From settler violence to cases like this, there is little or no accountability anymore in Israel.
