Kavli Affiliate: George Efstathiou | First 5 Authors: Stefan Heimersheim, Nina S. Sartorio, Anastasia Fialkov, Duncan R. Lorimer, | Summary: Fast Radio Bursts (FRBs) are recently-discovered extra-galactic radio transients which exhibit a distance-dependent dispersion of their signal, and thus can be used as cosmological probes. In this article we, for the first time, apply a […]
Kavli Affiliate: Andrey V. Kravtsov | First 5 Authors: Vadim A. Semenov, Andrey V. Kravtsov, Benedikt Diemer, , | Summary: We compare the performance of energy-based and entropy-conservative schemes for modeling nonthermal energy components, such as unresolved turbulence and cosmic rays, using idealized fluid dynamics tests and isolated galaxy simulations. While both methods are aimed […]
Kavli Affiliate: Edward H. Morgan | First 5 Authors: Tianjun Gan, Megan Bedell, Sharon Xuesong Wang, Daniel Foreman-Mackey, Jorge Meléndez | Summary: We report the discovery and characterization of a transiting warm sub-Neptune planet around the nearby bright ($V=8.75$ mag, $K=7.15$ mag) solar twin HD 183579, delivered by the Transiting Exoplanet Survey Satellite (TESS). The […]
