The Atacama Cosmology Telescope: The Persistence of Neutrino Self-Interaction in Cosmological Measurements
Christina D. Kreisch, Minsu Park, Erminia Calabrese +21
We use data from the Atacama Cosmology Telescope (ACT) DR4 to search for the presence of neutrino self-interaction in the cosmic microwave background. Consistent with prior works,…
Beyond dark energy Fisher forecasts: how DESI will constrain LCDM and quintessence models
Samuel Goldstein, Minsu Park, Marco Raveri +2
We baseline with current cosmological observations to forecast the power of the Dark Energy Spectroscopic Instrument (DESI) in two ways: 1. the gain in constraining power of parame…
What does a cosmological experiment really measure? Covariant posterior decomposition with normalizing flows
Tara Dacunha, Marco Raveri, Minsu Park +2
We present methods to rigorously extract parameter combinations that are constrained by data from posterior distributions. The standard approach uses linear methods that apply to G…
Reconstructing Quintessence
Minsu Park, Marco Raveri, Bhuvnesh Jain
We present an Effective Field Theory based reconstruction of quintessence models of dark energy directly from cosmological data. We show that current cosmological data possess enou…
CDM or self-interacting neutrinos? - how CMB data can tell the two models apart
Minsu Park, Christina D. Kreisch, Jo Dunkley +2
Of the many proposed extensions to the CDM paradigm, a model in which neutrinos self-interact until close to the epoch of matter-radiation equality has been shown to provide a g…
