Hubble Space Telescope and Ground-Based Observations of Type Ia Supernovae at Redshift 0.5: Cosmological Implications
A. Clocchiatti, B. Schmidt, A. Filippenko +26
We present observations of the Type Ia supernovae (SNe) 1999M, 1999N, 1999Q, 1999S, and 1999U, at redshift z~0.5. They were discovered in early 1999 with the 4.0~m Blanco telescope…
Many-body perturbation theory calculations using the yambo code
D. Sangalli, A. Ferretti, H. Miranda +17
yambo is an open source project aimed at studying excited state properties of condensed matter systems from first principles using many-body methods. As input, yambo requires groun…
Vacuum Energy Density Measured from Cosmological Data
J. Prat, C. Hogan, C. Chang +1
Within the CDM cosmological model, the absolute value of Einstein's cosmological constant , sometimes expressed as the gravitating mass-energy density of the physic…
The Dark Energy Spectrometer (DESpec): A Multi-Fiber Spectroscopic Upgrade of the Dark Energy Camera and Survey for the Blanco Telescope
F. Abdalla, J. Annis, D. Bacon +29
We describe an initiative to build and use the Dark Energy Spectrometer (DESpec), a wide-field spectroscopic survey instrument for the Blanco 4 meter telescope at Cerro Tololo Inte…
The Fall 2004 SDSS Supernova Survey
Masao Sako, Roger Romani, Josh Frieman +38
In preparation for the Supernova Survey of the Sloan Digital Sky Survey (SDSS) II, a proposed 3-year extension to the SDSS, we have conducted an early engineering and science run d…
Planning the Future of U.S. Particle Physics (Snowmass 2013): Chapter 8: Instrumentation Frontier
M. Demarteau, R. Lipton, H. Nicholson +211
These reports present the results of the 2013 Community Summer Study of the APS Division of Particles and Fields ("Snowmass 2013") on the future program of particle physics in the…
