Unknotting via null-homologous twists and multi-twists
Samantha Allen, Kenan Ince, Seungwon Kim +2
The untwisting number of a knot K is the minimum number of null-homologous twists required to convert K to the unknot. Such a twist can be viewed as a generalization of a crossing…

In its December 2019 edition, the \textit{Notices of the American Mathematical Society} published an essay critical of the use of diversity statements in academic hiring. The publi…
New Insights into the Physical Conditions and Internal Structure of a Candidate Proto-Globular Cluster
Molly K. Finn, Kelsey E. Johnson, Crystal L. Brogan +5
We present 0.1" resolution (10 pc) ALMA observations of a molecular cloud identified in the merging Antennae galaxies with the potential to form a globular cluster, nic…
Recovering the Physical Properties of Molecular Gas in Galaxies from CO SLED Modeling
J. Kamenetzky, G. C. Privon, D. Narayanan
Modeling of the spectral line energy distribution (SLED) of the CO molecule can reveal the physical conditions (temperature, density) of molecular gas in Galactic clouds and other…
