Kavli Affiliate: Alexander Ji | First 5 Authors: Alexander P. Ji, Anna Frebel, Volker Bromm, , | Summary: We model early star forming regions and their chemical enrichment by Population III (Pop III) supernovae with nucleosynthetic yields featuring high [C/Fe] ratios and pair-instability supernova (PISN) signatures. We aim to test how well these chemical abundance […]
Kavli Affiliate: Yu V. Nazarov | First 5 Authors: C. Padurariu, T. Jonckheere, J. Rech, R. Mélin, D. Feinberg | Summary: We describe the proximity effect in a short disordered metallic junction between three superconducting leads. Andreev bound states in the multi-terminal junction may cross the Fermi level. We reveal that for a quasi-continuous metallic […]
Fangzhou Jiang, Frank C. van den Bosch, , , | Summary: [[{“value”:”We use a semi-analytical model for the substructure of dark matter haloes to assess the too-big-to-fail (TBTF) problem. The model accurately reproduces the average subhalo mass and velocity functions, as well as their halo-to-halo variance, in N-body simulations. We construct thousands of realizations of […]
Kavli Affiliate: Austin Minnich | First 5 Authors: Austin J. Minnich, , , , | Summary: Boundary scattering of thermal phonons in thin solid films is typically analyzed using Fuchs-Sondheimer theory, which provides a simple equation to calculate the reduction of thermal conductivity as a function of the film thickness. However, this widely-used equation is […]
