Observing the Evolution of the Universe (2009)

Aguirre, James, Amblard, Alexandre, Ashoorioon, Amjad, Baccigalupi, Carlo, Balbi, Amedeo, Bartlett, James, ...

How did the universe evolve? The fine angular scale (l>1000) temperature and polarization anisotropies in the CMB are a Rosetta stone for understanding the evolution of the universe. Through detailed...

A New Era in Extragalactic Background Light Measurements: The Cosmic History of Accretion, Nucleosynthesis and Reionization (2009)

Cooray, Asantha, Amblard, Alexandre, Beichman, Charles, Benford, Dominic, Bernstein, Rebecca, Bock, James, ...

(Brief Summary) What is the total radiative content of the Universe since the epoch of recombination? The extragalactic background light (EBL) spectrum captures the redshifted energy released from...

Cost Optimized Interstellar Beacons: METI (2008)

Benford, James, Benford, Gregory, Benford, Dominic

This paper considers galactic scale Beacons from the point of view of expense to a builder on Earth. For fixed power density in the far field, what is the cost-optimum interstellar Beacon system?...

Cost Optimized Interstellar Beacons: SETI (2008)

Benford, Gregory, Benford, James, Benford, Dominic

What would SETI Beacon transmitters be like if built by civilizations with a variety of motivations, but who cared about cost? High-power transmitters might be built for wide variety of motives other...

ExoPTF Science Uniquely Enabled by Far-IR Interferometry: Probing the Formation of Planetary Systems, and Finding and Characterizing Exoplanets (2007)

Leisawitz, David, Armstrong, Tom, Bender, Chad, Benford, Dominic, Calzetti, Daniella, Carpenter, John, ...

By providing sensitive sub-arcsecond images and integral field spectroscopy in the 25 - 400 micron wavelength range, a far-IR interferometer will revolutionize our understanding of planetary system...

The Space Infrared Interferometric Telescope (SPIRIT): High-resolution imaging and spectroscopy in the far-infrared (2007)

Leisawitz, David, Baker, Charles, Barger, Amy, Benford, Dominic, Blain, Andrew, Boyle, Rob, ...

We report results of a recently-completed pre-Formulation Phase study of SPIRIT, a candidate NASA Origins Probe mission. SPIRIT is a spatial and spectral interferometer with an operating wavelength...

350 micron Galactic Center Dust Observations with SHARC II (2004)

Staguhn, Johannes, Benford, Dominic, Morris, Mark, Uchida, Keven

We present first and preliminary submillimeter continuum images of the Galactic Center region obtained with the new Caltech Submillimeter Observatory facility camera SHARC II. The instrument allows...
