Constraints on primordial non-Gaussianity from the cross-correlation of DESI Luminous Red Galaxies and CMB lensing
J. R. Bermejo-Climent, R. Demina, A. Krolewski +47
We use the angular cross-correlation between a luminous red galaxy (LRG) sample from the Dark Energy Spectroscopic Instrument (DESI) Legacy Survey data release DR9 and the …

An Agnostic Approach to Building Empirical Type Ia Supernova Light Curves: Evidence for Intrinsic Chromatic Flux Variation Using Nearby Supernova Factory Data
Jared Hand, A. G. Kim, G. Aldering +35
We present a new empirical Type Ia supernova (SN Ia) model with three chromatic flux variation templates: one phase dependent and two phase independent. No underlying dust extincti…
