18:30 Aps.org Editors' Suggestions Early dark sector, the Hubble tension, and the swampland

Author(s): Evan McDonough, Meng-Xiang Lin, J. Colin Hill, Wayne Hu, and Shengjia ZhouThis work investigates the interplay of the Hubble tension, Early Dark Energy (EDE), and the swampland distance conjecture. The latter predicts a tower of light states for large field excursions, while EDE is a scalar field model to alleviate the Hubble tension which indeed requires Planckian field excursions, but also leads to tensions with large-scale structure (LSS) probes. The authors consider exponentially EDE-dependent masses of dark matter with the distance conjecture constant, which supposedly is a positive constant of O(1), as a free parameter. Using a large set of different catalogs of experiments, fitting also LSS data, a mild tension with the swampland distance conjecture is observed that constrains the constant to be significantly less than one.

19:33 Phys.org Hubble gazes at a star-studded skyfield

This star-studded image from the NASA/ESA Hubble Space Telescope shows the heart of the globular cluster NGC 6638 in the constellation Sagittarius. The star-strewn observation highlights the density of stars at the heart of globular clusters, which are stable, tightly bound groups of tens of thousands to millions of stars. To capture the data in this image, Hubble used two of its cutting-edge astronomical instruments: Wide Field Camera 3 and the Advanced Camera for Surveys.
