Dark Matter "Collider" from Inelastic Boosted Dark Matter
Doojin Kim, Jong-Chul Park, Seodong Shin
We propose a novel dark matter (DM) detection strategy for the models with non-minimal dark sector. The main ingredients in the underlying DM scenario are a boosted DM particle and…
Boosted Dark Matter at the Deep Underground Neutrino Experiment
Haider Alhazmi, Kyoungchul Kong, Gopolang Mohlabeng +1
We investigate the detection prospects of a non-standard dark sector in the context of boosted dark matter. We consider a scenario where two stable particles have a large mass diff…
Topological stability and pseudo-orbit tracing property of group actions
Nhan-Phu Chung, Keonhee Lee
In this note we extend the concept of topological stability from homeomorphisms to group actions on compact metric spaces, and prove that if an action of a finitely generated group…
Differences between radio-loud and radio-quiet gamma-ray pulsars as revealed by Fermi
C. Y. Hui, Jongsu Lee, J. Takata +2
By comparing the properties of non-recycled radio-loud ray pulsars and radio-quiet ray pulsars, we have searched for the differences between these two populations. We found…
Boyle's Conjecture and perfect localizations
Jaime Castro Pérez, Mauricio Medina Bárcenas, José Ríos Montes +1
In this article we study the behavior of left QI-rings under perfect localizations. We show that a perfect localization of a left QI-ring is a left QI-ring. We prove that Boyle's c…
Bright Metal-Poor Stars from the Hamburg/ESO Survey. II. A Chemodynamical Analysis
Timothy C. Beers, Vinicius M. Placco, Daniela Carollo +6
We obtain estimates of stellar atmospheric parameters for a previously published sample of 1777 relatively bright (9 < B < 14) metal-poor candidates from the Hamburg/ESO Survey. Th…
