Status of direct searches for WIMP dark matter
Richard W. Schnee
Astrophysical observations indicate that about 23% of the energy density of the universe is in the form of non-baryonic particles beyond the standard model of particle physics. One…
The Stellar Populations of M33's Outer Regions III: Star Formation History
Michael K. Barker, Ata Sarajedini, Doug Geisler +2
We present a detailed analysis of the star formation history (SFH) of three fields in M33 located ~ 4 - 6 visual scale lengths from its nucleus. These fields were imaged with the A…
The Stellar Populations of M33's Outer Regions II: Deep ACS Imaging
Michael K. Barker, Ata Sarajedini, Doug Geisler +2
Studying the stellar populations in the outskirts of spiral galaxies can provide important constraints on their structure, formation, and evolution. To that end, we present VI phot…
Improved Measurements of the CMB Power Spectrum with ACBAR
C. L. Kuo, P. A. R. Ade, J. J. Bock +13
We report improved measurements of temperature anisotropies in the cosmic microwave background (CMB) radiation made with the Arcminute Cosmology Bolometer Array Receiver (ACBAR). I…
A Neutron Multiplicity Meter for Deep Underground Muon-Induced High Energy Neutron Measurements
R. Hennings-Yeomans, D. S. Akerib
We present the design of an instrument capable of measuring the high energy (60 MeV) muon-induced neutron flux deep underground. The instrument is based on applying the Gd-loade…
What's the trouble with anthropic reasoning?
Roberto Trotta, Glenn D. Starkman
Selection effects in cosmology are often invoked to "explain" why some of the fundamental constant of Nature, and in particular the cosmological constant, take on the value they do…
