Sensitivity of Next-Generation CMB Surveys to Neutrinos and Other Light Relics
Cynthia Trendafilova, Srinivasan Raghunathan, Benjamin Wallisch +33
Neutrinos and other light relics leave characteristic imprints in the cosmic microwave background anisotropies, making their observation a sensitive probe of the particle content a…
Dark winds on the horizon: Prospects for detecting neutrino and hot dark matter wakes in large-scale structure
Caio B. de S. Nascimento, Marilena Loverde
We explore the cosmological signatures of neutrino and Hot Dark Matter (HDM) wakes, which refers to the preferential accumulation of neutrinos (or, more broadly, HDM particles) dow…
Where does non-Universality in Assembly Bias come from?
Charuhas Shiveshwarkar, Marilena Loverde, Christopher M. Hirata +1
Constraints on local primordial non-Gaussianity (LPnG) obtained from galaxy power spectra are limited by the perfect degeneracy between the LPnG parameter and the bias…
Cosmological perturbation theory for large scale structure in phase space
Caio Nascimento, Marilena Loverde
We develop a framework for Large Scale Structure (LSS) perturbation theory, that solves the Vlasov-Poisson system of equations for the distribution function in full phase space. Th…
The Spectroscopic Stage-5 Experiment
Robert Besuner, Arjun Dey, Alex Drlica-Wagner +106
The existence, properties, and dynamics of the dark sectors of our universe pose fundamental challenges to our current model of physics, and large-scale astronomical surveys may be…
Abundance and properties of dark radiation from the cosmic microwave background
Murali M. Saravanan, Thejs Brinckmann, Marilena Loverde +1
We study the cosmological signatures of new light relics that are collisionless like standard neutrinos or are strongly interacting. We provide a simple and succinct rephrasing of…
