Large Scale Structure as a Probe of Gravitational Slip
Scott F. Daniel, Robert R. Caldwell, Asantha Cooray +1
A new time-dependent, scale-independent parameter, \varpi, is employed in a phenomenological model of the deviation from General Relativity in which the Newtonian and longitudinal…
The effects of Chern-Simons gravity on bodies orbiting the Earth
Tristan L. Smith, Adrienne L. Erickcek, Robert R. Caldwell +1
One of the possible low-energy consequences of string theory is the addition of a Chern-Simons term to the standard Einstein-Hilbert action of general relativity. It can be argued…
Constraints on a New Post-General Relativity Cosmological Parameter
Robert Caldwell, Asantha Cooray, Alessandro Melchiorri
A new cosmological variable is introduced which characterizes the degree of departure from Einstein's General Relativity (GR) with a cosmological constant. The new parameter, \varp…
Gravitation of the Casimir Effect and the Cosmological Non-Constant
R. R. Caldwell
Whereas the total energy in zero-point fluctuations of the particle physics vacuum gives rise to the cosmological constant problem, differences in the vacuum give rise to real phys…
Cosmological Parameters, Dark Energy and Large Scale Structure
S. E. Deustua, R. Caldwell, P. Garnavich +2
We review the current status of cosmological parameters, dark energy and large-scale structure, from a theoretical and observational perspective. We first present the basic cosmolo…
Galactic Observations at 31, 42 and 144~GHz with the Mobile Anisotropy Telescope
J. L. Puchalla, R. Caldwell, K. L. Cruz +8
We present multi-frequency maps of a portion of the Galactic Plane centered on a declination of -60 degrees with resolutions ranging from 0.2 to 0.9 degrees. The maps are optimized…
