The effect of metallicity on the Cepheid P-L relation, from a Baade-Wesselink analysis of SMC Cepheids
Jesper Storm, Bruce W. Carney, Anne M. Fry
We present results based on a Baade-Wesselink analysis of Cepheids in the Small Magellanic Cloud. The Baade-Wesselink analysis provides individual luminosities for these metal-poor…
The Molecular ISM in Low Surface Brightness Disk Galaxies
Chris Mihos, Marco Spaans, Stacy McGaugh
We present models for the interstellar medium in disk galaxies. In particular, we investigate whether the ISM in low surface brightness galaxies can support a significant fraction…
Gravitational lensing statistics and constraints on the cosmological constant revisited
Yu-Chung N. Cheng, Lawrence M. Krauss
We re-analyze constraints on the cosmological constant that can be obtained by examining the statistics of strong gravitational lensing of distant quasars by intervening galaxies,…
Tracing the Outer Structure of the Sagittarius Dwarf Galaxy: Detections at Angular Distances Between 10 and 34 Degrees
Mario Mateo, Edward W. Olszewski, Heather L. Morrison
We have obtained deep photometric data in 24 fields along the southeast extension of the major axis of the Sagittarius dwarf spheroidal (Sgr dSph) galaxy, and in four fields along…
New Signatures and Sources for the Detection of WIMP Dark Matter in the Solar System
Lawrence M. Krauss
I first outline new results on the angular modulation of WIMP dark matter scattering on targets in terrestrial laboratories, based on our uncertainties of the WIMP halo distributio…
A New WIMP Population in the Solar System and New Signals for Dark-Matter Detectors
Thibault Damour, Lawrence M. Krauss
We describe in detail how perturbations due to the planets can cause a sub-population of WIMPs captured by scattering in surface layers of the Sun to evolve to have orbits which no…
A New Analysis of RR Lyrae Kinematics in the Solar Neighborhood
John C. Martin, Heather L. Morrison
Full space velocities are computed for a sample of 130 nearby RR Lyrae variables using both ground-based and Hipparcos proper motions. In many cases proper motions from multiple so…
The Hubble Constant from Observations of the Brightest Red Giant Stars in a Virgo-Cluster Galaxy
W. E. Harris, P. R. Durrell, M. J. Pierce +1
The Virgo and Fornax clusters of galaxies play central roles in determining the Hubble constant H_0. A powerful and direct way of establishing distances for elliptical galaxies is…
A New Solar System Population of WIMP Dark Matter
Thibault Damour, Lawrence M. Krauss
Perturbations due to the planets combined with the non-Coulomb nature of the gravitational potential in the Sun imply that WIMPs that are gravitationally captured by scattering in…
Triaxial Halos and Cusps
Steinn Sigurdsson, Chris Mihos, Lars Hernquist +1
We present --body models for triaxial elliptical galaxies or halos of galaxies, which are fully self--gravitating, have near constant axis ratio as a function of radius and a $r…
Of Matter Less Repulsive than a Cosmological Constant
Neil J. Cornish, Glenn D. Starkman
The case grows ever stronger that the average density of matter, ordinary and dark, is less than the critical density required for a flat universe. However, most of determinations…
Looking Down the Light Cone: Can Deep Redshift Surveys Alone Measure the Power Spectrum?
Andrew A. de Laix, Glenn D. Starkman
We analyze the window functions for the spherical harmonic mode estimators of all--sky, volume limited surveys considering evolutionary effects along the past light--cone which inc…
Gravitational Lensing and Dark Structures
Yu-Chung N. Cheng, Lawrence M. Krauss
We examine whether a cosmologically significant distribution of dark galaxy group or cluster-sized objects can have an optical depth for multiple imaging of distant background sour…
Circles in the Sky: Finding Topology with the Microwave Background Radiation
Neil Cornish, David Spergel, Glenn Starkman
If the universe is finite and smaller than the distance to the surface of last scatter, then the signature of the topology of the universe is writ large on the microwave background…
