Congratulations to Dr. Helena García Escudero in successfully defending her PhD dissertation today at UCI Department of Physics & Astronomy, titled “ΛCDM and Beyond: Neutrinos and the Puzzle of Cosmological Tensions.” She joins the USC Department of Physics & Astronomy as a postdoctoral scholar in December!

NASA's James Webb Space Telescope has discovered massive galaxies at 37 billion light years away, when the Universe was ~1% of its current age (z~25!). Galaxy formation appears at odds with the efficiencies capable of making such galaxies at beyond 100% (the solid purple line).

Work led by #UCIrvine NSF Graduate Research Fellow Jay Krishnan shows that systematic uncertainties in the inferred mass, along with the steeply falling halo mass function at these scales, leads to large uncertainties that asymmetrically prefer lower efficiencies. The asymmetry is caused by the steeply falling mass function: there are many more smaller galaxies to upscatter into your sample (upper orange curves) than there are larger galaxies to downscatter into it (lower orange curves).

Many new physics models have been proposed in response to the apparently anomalous JWST galaxies, and we provide the code to test these models when more galaxies are detected and uncertainties are reduced.

First paper submission today for #UCIrvine graduate fellow Jay Krishnan! There is much interest in NASA's James Webb Space Telescope potentially showing early galaxy formation as incompatible with standard cosmology and structure formation We show that current systematic uncertainties, when combined with the steeply falling mass function of galaxies, relax the apparent tension. We provide the tools to test cosmology as new detections come from JWST. The paper Is scheduled to be on the arXiv tonight.

It turns out the Hubble expansion rate problem may be connected to another anomaly: evidence of neutrino oscillations at short baselines. One of the key figures from the work led by #UCIrvine graduate fellow Helena García Escudero shows that one of cosmology’s strongest probes—baryon acoustic oscillations—allows neutrino number and mass to increase together. This simultaneously relaxes constraints on additional massive neutrinos, which are favored by both the Hubble tension and short-baseline neutrino anomalies.
