Measuring Cosmic Neutrino Masses Independently of Dark Energy
Frank J. Qu, Fei Ge, Hanyue Wang +4
Neutrino oscillations establish that neutrinos are massive, providing the only laboratory detection of physics beyond the Standard Model. Direct kinematic experiments bound the ele…

Galaxy-Multiplet Clustering from DESI DR2
Hanyue Wang, Daniel J. Eisenstein, Jessica Nicole Aguilar +44
We present an efficient estimator for higher-order galaxy clustering using small groups of nearby galaxies, or multiplets. Using the Luminous Red Galaxy (LRG) sample from the Dark…

A Spectroscopic Search for Optical Emission Lines from Dark Matter Decay
Hanyue Wang, Daniel J. Eisenstein, Jessica Nicole Aguilar +19
We search for narrow-line optical emission from dark matter decay by stacking dark-sky spectra from the Dark Energy Spectroscopic Instrument (DESI) at the redshift of nearby galaxi…
