A dwarf irregular galaxy at the edge of the Local Group: Stellar populations and distance of IC 5152

Albert A. Zijlstra, Dante Minniti

We have obtained V and I-band photometry for about 700 stars in the field of the dwarf irregular galaxy IC 5152, previously considered a possible member of the Local Group. Deep VI…

The Vacuum Energy in a Condensate Model for Spacetime

George Chapline

It is shown that a simple model for 4-dimensional quantum gravity based on a 3-dimensional generalization of anyon superconductivity can be regarded as a discrete form of Polyakov'…

A Polarimetric Search for Hidden Quasars in Three Radio Selected Ultraluminous Infrared Galaxies

Hien D. Tran, M. S. Brotherton, S. A. Stanford +4

We have carried out a spectropolarimetric search for hidden broad-line quasars in three ultraluminous infrared galaxies (ULIRGs) discovered in the positional correlations between s…

Selection Effects, Biases, and Constraints in the Calan/Tololo Supernova Survey

Mario Hamuy, Philip A. Pinto

We use Monte Carlo simulations of the Calan/Tololo photographic supernova survey to show that a simple model of the survey's selection effects accounts for the observed distributio…

Continuation for Nonlinear Elliptic Partial Differential Equations Discretized by the Multiquadric Method

A. I. Fedoseyev, M. J. Friedman, E. J. Kansa

The Multiquadric Radial Basis Function (MQ) Method is a meshless collocation method with global basis functions. It is known to have exponentional convergence for interpolation pro…

Galaxy Disruption as the Origin of Intracluster Light in the Coma Cluster

Michael D. Gregg, Michael J. West

Although the existence of a faint background of starlight in the core of the Coma cluster has been well established (1,2), its origin is uncertain. This vast sea of stars could hav…
