Binaries with neutron stars | In this paper, the second of a series, we study the stellar dynamical and evolutionary processes leading to the formation of compact binaries containing neutron stars (NSs) in dense globular clusters (GCs). For this study, 70 dense clusters were simulated independently, with a total stellar mass ~2x10^7Msun, exceeding ... | [

13862779 | 0706.4071 | 2007-06-27 | Cosmology and Astrophysics of Minimal Dark Matter | We consider DM that only couples to SM gauge bosons and fills one gauge multiplet, e.g. a fermion 5-plet (which is automatically stable), or a wino-like 3-plet. We revisit the computation of the cosmological relic abundance including non-perturbative corrections. The predicted mass of e.g. the 5-plet increases from 4.4... | [

The relation thus far has been constrained using a sample of ~40 stars in young open clusters, ranging in initial mass from ~2.75 -- 7 Msun, ... | [

This model directly maps on to an easy-axis $S=1/2$ XXZ model on the kagome lattice and is also related, at large $V/t$, to a quantum dimer model on the triangular lattice.

Here we describe a novel approach to realize strong nonlinear interactions at the single-photon level. Our method makes use of recently ... | [
