Dark Energy Survey Year 1 Results: Cosmological Constraints from Cluster Abundances and Weak Lensing

Kavli Affiliate: Eli Rykoff | First 5 Authors: DES Collaboration, Tim Abbott, Michel Aguena, Alex Alarcon, Sahar Allam | Summary: We perform a joint analysis of the counts and weak lensing signal of redMaPPer clusters selected from the Dark Energy Survey (DES) Year 1 dataset. Our analysis uses the same shear and source photometric redshifts […]

The distinct stellar-to-halo mass relations of satellite and central galaxies: insights from the IllustrisTNG simulations

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Christoph Engler, Annalisa Pillepich, Gandhali D. Joshi, Dylan Nelson, Anna Pasquali | Summary: We study the stellar-to-halo mass relation (SHMR) for central and satellite galaxies with total dynamical masses above 10^10.5 Msun using the suite of cosmological magneto-hydrodynamical simulations IllustrisTNG. In particular, we quantify environmental effects on […]

Evidence for a magnetic-field induced ideal type-II Weyl state in antiferromagnetic topological insulator Mn(Bi1-xSbx)2Te4

Kavli Affiliate: Alessandra Lanzara | First 5 Authors: Seng Huat Lee, David Graf, Yanglin Zhu, Hemian Yi, Samuel Ciocys | Summary: The discovery of Weyl semimetals (WSMs) has fueled tremendous interest in condensed matter physics. WSMs require breaking of either inversion symmetry (IS) or time-reversal symmetry (TRS); they can be categorized into type-I and type-II […]
