  5. Hints of Primordial Magnetic Fields at Recombination and Implications for the Hubble Tension: arxiv.org/abs/2503.09599 -> Primordial magnetic fields could resolve the #HubbleTension and other cosmic mysteries: www6.slac.stanford.edu/news/20 - an international team of researchers simulated magnetic forces in the early universe and found they could bridge the gap between the observed and calculated rates of the universe’s expansion.

  10. Astronomy is facing a real #Cosmology crisis. New observations clash with theory: vast structures defy the #CosmologicalPrinciple, the #HubbleTension persists, and #JWST reveals mature galaxies far earlier than expected. Combined with puzzles in #DarkMatter and #DarkEnergy, the evidence suggests our standard model is incomplete. Rather than doom, this may be a historic “#MercuryMoment” — a rare phase where contradictions drive breakthroughs and reshape our view of the universe.

  11. Everyone wants something better than ΛCDM

    There’s a nice short review article on arXiv today by Mike Turner. I wasn’t going to share it because it hasn’t got any pictures in it, but changed my mind.

    Here is the abstract

    The current cosmological paradigm, ΛCDM, is characterized (b) its expansive description of the history of the Universe, its deep connections to particle physics and the large amounts of data that support it. Nonetheless, ΛCDM’s critics argue that it has been falsified or must be discarded for various reasons. Critics and boosters alike do agree on one thing: it is the not the final cosmological theory and they are anxious to see it replaced by something better! I review the status of ΛCDM, provide my views of the path forward, and discuss the role that the “Hubble tension” might play.

    arXiv:2510.05483

    To make up for the lack of pictures in the article, here’s the first image that came up when I did a search for “ΛCDM”:

  14. Fun to work out with #UCIrvine graduate fellow Helena Garcia Escudero the details of why extra, sterile neutrinos are preferred (!!) by cosmology when adopting the local Cepheid measurement of the Hubble expansion rate. It ties into why baryon acoustic oscillations allow for simultaneous increase in relativistic energy density and neutrino mass, and it’s nontrivial why that happens. The paper will appear tomorrow on the arXiv, following up on a lead in our previous work arxiv.org/abs/2412.05451

    Prior-free cosmological parameter estimation of Cosmicflows-4

    The analysis suggests a Hubble constant value of 75.8±0.4 km/s /Mpc, exacerbating (or independently confirming) the existing "Hubble Tension".
