Exploring the distance-redshift relation with gravitational wave standard sirens and tomographic weak lensingJun 29 2018Oct 11 2018Gravitational waves from inspiraling compact objects provide us with information of the distance scale since we can infer the absolute luminosity of the source from analysis of the wave form, which is known as standard sirens. The first detection of the ... More

A New Class of Retrocausal ModelsMay 24 2018Globally-constrained classical fields provide a unexplored framework for modeling quantum phenomena, including apparent particle-like behavior. By allowing controllable constraints on unknown past fields, these models are retrocausal but not retro-signaling, ... More

X-ray observations of powerful AGN outflows - implications for feedbackJul 25 2013Highly ionised winds with velocities ~ 0.1-0.2c were first detected in X-ray spectra of non-BAL AGN a decade ago. Subsequent observations and archival searches have shown such winds to be a common feature of luminous AGN, increasing the belief that powerful ... More

Purely infinite, simple C*-algebras arising from free product constructions, IINov 02 1999Certain reduced free products of C*-algebras, (A,phi)=(A_1,phi_1)*(A_2,\phi_2), taken with respect to faithful states, at least one of which is not a trace, are shown to be purely infinite and simple. It is assumed that one of the A_i contain a partial ... More
