Kavli Affiliate: Bradford Benson | First 5 Authors: Ian Gullett, Bradford Benson, Robert Besuner, Richard Bihary, John Carlstrom | Summary: Telescopes measuring cosmic microwave background (CMB) polarization on large angular scales require exquisite control of systematic errors to ensure the fidelity of the cosmological results. In particular, far-sidelobe contamination from wide angle scattering is a […]

Kavli Affiliate: Alexander Ji | First 5 Authors: Anna Frebel, Alexander P. Ji, , , | Summary: This chapter presents an overview of the recent progress on spectroscopic observations of metal-poor stars with r-process element signatures found in the Milky Way’s stellar halo and satellite dwarf galaxies. Major empirical lessons related to the origins of […]

Kavli Affiliate: Salman Habib | First 5 Authors: James M. Sullivan, J. D. Emberson, Salman Habib, Nicholas Frontiere, | Summary: 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 impact of massive neutrinos should therefore be included in these […]

Kavli Affiliate: Salman Habib | First 5 Authors: Danila Korytov, Esteban Rangel, Lindsey Bleem, Nicholas Frontiere, Salman Habib | Summary: The galaxy distribution in dark matter-dominated halos is expected to approximately trace the details of the underlying dark matter substructure. In this paper we introduce halo `core-tracking’ as a way to efficiently follow the small-scale […]

Kavli Affiliate: Michael D. Gladders | First 5 Authors: Kate Napier, Keren Sharon, Håkon Dahle, Matthew Bayliss, Michael D. Gladders | Summary: Tension between cosmic microwave background-based and distance ladder-based determinations of the Hubble constant ${rm H}_{rm 0}$ motivates pursuit of independent methods that are not subject to the same systematic effects. A promising alternative, […]
