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-…
The Betelgeuse Project III: Merger Characteristics
J. M. Sullivan, S. Nance, J. Craig Wheeler
We previously proposed that Betelgeuse might have been spun up by accreting a companion of about 1 solar mass. Here we explore in more detail the possible systematics of such a mer…
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 Betelgeuse Project II: Asteroseismology
S. Nance, J. M. Sullivan, M. Diaz +1
We explore the question of whether the interior state of massive red supergiant supernova progenitors can be effectively probed with asteroseismology. We have computed a suite of t…
