Galaxy bias in the era of LSST: perturbative bias expansions
Andrina Nicola, Boryana Hadzhiyska, Nathan Findlay +14
Upcoming imaging surveys will allow for high signal-to-noise measurements of galaxy clustering at small scales. In this work, we present the results of the LSST bias challenge, the…
Improving initialization and evolution accuracy of cosmological neutrino simulations
James M. Sullivan, J. D. Emberson, Salman Habib +1
Neutrino mass constraints are a primary focus of current and future large-scale structure (LSS) surveys. Non-linear LSS models rely heavily on cosmological simulations -- the impac…
An Analytic Hybrid Halo + Perturbation Theory Model for Small-scale Correlators: Baryons, Halos, and Galaxies
James M. Sullivan, Uros Seljak, Sukhdeep Singh
We update Halo Zeldovich Perturbation Theory (HZPT), an analytic model for the two-point statistics of dark matter, to describe halo and galaxy clustering, and galaxy-matter cross-…
Minimum star-forming halo mass in axion cosmology
James M. Sullivan, Shingo Hirano, Volker Bromm
Elucidating the particle physics nature of dark matter (DM) is one of the great challenges in modern science. The current lack of any direct DM detections in the laboratory heighte…
The clustering of galaxies in the SDSS-III Baryon Oscillation Spectroscopic Survey: Evolution of higher-order correlations demonstrated with Minkowski Functionals
James M. Sullivan, Alexander Wiegand, Daniel J. Eisenstein
We probe the higher-order galaxy clustering in the final data release (DR12) of the Sloan Digital Sky Survey Baryon Oscillation Spectroscopic Survey (BOSS) using germ-grain Minkows…
First star formation in ultra-light particle dark matter cosmology
Shingo Hirano, James M. Sullivan, Volker Bromm
The formation of the first stars in the high-redshift Universe is a sensitive probe of the small-scale, particle physics nature of dark matter (DM). We carry out cosmological simul…
