or : DESI constraints on relative baryon-CDM perturbations
Ananda F. Smith, Mikhail M. Ivanov, Roger de Belsunce +3
We carry out a search for the relative baryon-cold dark matter (CDM) density and velocity modes in the DESI full-shape (FS) data, and investigate whether DESI's preference for evol…
Cosmological Concordance in an Especially Opaque Universe: A Tentative Cosmological Detection of Physical Neutrino Mass in CDM
James M. Sullivan, Roger de Belsunce, Mikhail M. Ivanov
The measurement of the sum of neutrino masses is among the primary promises of precision cosmology, achievable by combining complementary early- and late-Universe probes. However,…
Analytic compression of the effective field theory of the Lyman-alpha forest
N. G. Karaçaylı, M. Ivanov, R. de Belsunce +3
The 1D flux power spectrum () of the Ly forest provides an exceptionally high-resolution probe of structure formation down to small scales ($k\approx1-10~\text{…
Reanalyzing DESI DR1: 4. Percent-Level Cosmological Constraints from Combined Probes and Robust Evidence for the Normal Neutrino Mass Hierarchy
Mikhail M. Ivanov, James M. Sullivan, Roger de Belsunce +4
We present cosmological parameter measurements from the full combination of DESI DR1 galaxy clustering data, described with large-scale structure effective field theory. By incorpo…
