Boosting the optical depth to Thomson scattering with primordial black hole evaporation at high redshift

Isaac Sierra, Gabriel P. Lynch, Lloyd Knox +3

BAO and CMB data are somewhat discrepant when interpreted in the context of Λcdm, discrepancies that show up as a `matter density deficit' and as a `CMB lensing excess'. One poss…

JWST & the Waz Arc I: Spatially Resolving the Physical Conditions within a Post-Starburst Galaxy at Redshift 5 with NIRSpec IFS

Taylor A. Hutchison, Gourav Khullar, Jane R. Rigby +22

We present NIRSpec/IFS observations of a rest-frame UV-bright, massive (M∗​∼1010 M⊙​, zAB​=20.5) galaxy highly magnified by gravitational-lensing observed just…
