Wrote this up for a friend, thought I should share it more widely.
Fritz Zwicky https://en.wikipedia.org/wiki/Fritz_Zwicky was a notoriously difficult teacher and his assignments were brutal. We're in the 1930s or 1940s.
The students (Caltech) complain to the other…

Thirteen New M Dwarf + T Dwarf Pairs Identified with WISE/NEOWISE
We present the discovery of 13 new widely separated T dwarf companions to M dwarf primaries, identified using WISE/NEOWISE data by the CatWISE and Backyard Worlds: Planet 9 projects. This sample represents a $\sim$60% increase in the number of known M+T systems, and allows us to probe the most extreme products of binary/planetary system formation, a discovery space made available by the CatWISE2020 catalog and the Backyard Worlds: Planet 9 effort. Highlights among the sample are WISEP J075108.7…

Robert Millikan, Japanese Internment, and Eugenics
Robert A. Millikan (1868-1953) was the second American to win the Nobel Prize in physics. At the peak of his influence, no scientist save Einstein was more admired by the American public. Millikan, the head of the California Institute of Technology (Caltech) during its first 24 years, oversaw its rapid growth into one of the leading scientific institutions of the world. In response to demands for social justice, Caltech reached a decision to strip Millikan of honors (such as the library named a…

Connection between galaxy morphology and dark-matter halo structure I: a running threshold for thin discs and size predictors from the dark sector
We present a series of studies on the connection between galaxy morphology and the structure of host dark-matter (DM) haloes using cosmological simulations. In this work, we introduce a new kinematic decomposition scheme that features physical identification of morphological components, enabling robust separation of thin and thick discs; and measure a wide range of halo properties, including their locations in the cosmic web, internal structures, and assembly histories. Our analysis of the TNG5…
