Non-commutative resolutions for the discriminant of the complex reflection group
Simon May
We show that for the family of complex reflection groups appearing in the Shephard--Todd classification, the endomorphism ring of the reduced hyperplane arrangement $A…
Analytic Model for Covariance Matrices of the 2-, 3-, and 4-Point Correlation Functions in the Gaussian Random Field Approximation
Jessica Chellino, Alessandro Greco, Simon May +1
Analyses of the galaxy N-Point Correlation Functions (NPCFs) have a large number of degrees of freedom, meaning one cannot directly estimate an invertible covariance matrix purely…
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…
The Diversity of Core Halo Structure in the Fuzzy Dark Matter Model
Hei Yin Jowett Chan, Elisa G. M. Ferreira, Simon May +2
In the fuzzy dark matter (FDM) model, gravitationally collapsed objects always consist of a solitonic core located within a virialised halo. Although various numerical simulations…
Updated bounds on ultra-light dark matter from the tiniest galaxies
Simon May, Neal Dalal, Andrey Kravtsov
The particle mass of dark matter (DM) was previously constrained using kinematics of ultra-faint dwarf galaxies to . This constraint, which excl…
Structure formation in large-volume cosmological simulations of fuzzy dark matter: Impact of the non-linear dynamics
Simon May, Volker Springel
An ultra-light bosonic particle of mass around is of special interest as a dark matter candidate, as it both has particle physics motivations, and may g…
