Transition from traveling fronts to diffusion-limited growth in expanding populations
Louis Brezin, Kyle J. Shaffer, Kirill S. Korolev
Reaction-diffusion equations describe various spatially extended processes that unfold as traveling fronts moving at constant velocity. We introduce and solve analytically a model…
The influence of AGN feedback on star formation in red spiral galaxies
Moreom Akter, Wayne A. Barkhouse, Sandanuwan P Kalawila Vithanage +2
We investigated the influence of Active Galactic Nuclei (AGN) feedback on star formation in red spiral galaxies by analyzing a sample of 324 red and 273 blue face-on spirals select…
Detection of molecular hydrogen in a neutron beam lifetime experiment
J. Caylor, R. Biswas, B. Crawford +10
One method of determining the free neutron lifetime involves the absolute counting of neutrons and trapped decay protons. In such experiments, a cold neutron beam traverses a segme…
On the Diameter of Undirected Cayley Graphs of Finite Abelian Groups
Bela Bajnok, W. Kyle Beatty
Let be a positive integer. Our goal is to find all finite abelian groups that contain a -subset for which the undirected Cayley graph has diameter at most $…
Critical groups of arithmetical structures on star graphs and complete graphs
Kassie Archer, Alexander Diaz-Lopez, Darren Glass +1
An arithmetical structure on a finite, connected graph without loops is an assignment of positive integers to the vertices that satisfies certain conditions. Associated to each of…
Gas sloshing and cold fronts in pre-merging galaxy cluster Abell 98
Arnab Sarkar, Scott Randall, Yuanyuan Su +10
We present deep Chandra observations of the pre-merger galaxy cluster Abell 98. Abell 98 is a complex merging system. While the northern (A98N) and central subclusters (A98S) are m…
