Constraints on local primordial non-Gaussianity with 3d Velocity Reconstruction from the Kinetic Sunyaev-Zeldovich Effect
Alex Laguë, Mathew S. Madhavacheril, Kendrick M. Smith +2
The cosmic velocity field is an unbiased probe of the total matter distribution but is challenging to measure directly at intermediate and high redshifts. The large-scale velocity…
Improved Halo Model Calibrations for Mixed Dark Matter Models of Ultralight Axions
Tibor Dome, Simon May, Alex Laguë +5
We study the implications of relaxing the requirement for ultralight axions to account for all dark matter in the Universe by examining mixed dark matter (MDM) cosmologies with axi…
Constraints on Dark Matter-Dark Energy Scattering from ACT DR6 CMB Lensing
Alex Laguë, Fiona McCarthy, Mathew Madhavacheril +2
The predicted present-day amplitude of matter fluctuations based on cosmic microwave background (CMB) anisotropy data has sometimes been found discrepant with more direct measureme…
Cosmological simulations of mixed ultralight dark matter
Alex Laguë, Bodo Schwabe, Renée Hložek +2
The era of precision cosmology allows us to test the composition of the dark matter. Mixed ultralight or fuzzy dark matter (FDM) is a cosmological model with dark matter composed o…
Ultra-light axions and the tension: joint constraints from the cosmic microwave background and galaxy clustering
Keir K. Rogers, Renée Hložek, Alex Laguë +5
We search for ultra-light axions as dark matter (DM) and dark energy particle candidates, for axion masses , by…
Evolving Ultralight Scalars into Non-Linearity with Lagrangian Perturbation Theory
Alex Laguë, J. Richard Bond, Renée Hložek +2
Many models of high energy physics suggest that the cosmological dark sector consists of not just one, but a spectrum of ultralight scalar particles with logarithmically distribute…
Prospects and Limitations for Constraining Light Relics with Primordial Abundance Measurements
Alex Laguë, Joel Meyers
The light relic density affects the thermal and expansion history of the early Universe leaving a number of observable imprints. We focus on the primordial abundances of light elem…
