There are multiple ways in which to select post-starburst galaxies in the literature. In this work, we present a study into how two well-used selection techniques have consequences…
Detection of magnetized quark-nuggets, a candidate for dark matter
J. Pace VanDevender, Aaron P. VanDevender, T. Sloan +7
Quark nuggets are theoretical objects composed of approximately equal numbers of up, down, and strange quarks and are also called strangelets and nuclearites. They have been propos…
