Delensing Gravitational Wave Standard Sirens with Shear and Flexion Maps (2009)

Shapiro, Charles, Bacon, David, Hendry, Martin, Hoyle, Ben

Supermassive black hole binary systems (SMBHB) are standard sirens -- the gravitational wave analogue of standard candles -- and if discovered by gravitational wave detectors, they could be used as...

Less than 10 percent of star formation in z=0.6 massive galaxies is triggered by major interactions (2009)

Robaina, Aday R., Bell, Eric F., Skelton, Rosalind E., McIntosh, Daniel H., Somerville, Rachel S., Zheng, Xianzhong, ...

Both observations and simulations show that major tidal interactions or mergers between gas-rich galaxies can lead to intense bursts of starformation. Yet, the average enhancement in star formation...

Optically-passive spirals: The missing link in gradual star formation suppression upon cluster infall (2009)

Wolf, Christian, Aragón-Salamanca, Alfonso, Balogh, Michael, Barden, Marco, Bell, Eric F., Gray, Meghan E., ...

Galaxies migrate from the blue cloud to the red sequence when their star formation is quenched. Here, we report on galaxies quenched by environmental effects and not by mergers or strong AGN as often...

Analysis of the effects of removing redundant header information in persistent HTTP connections (2008)

Timothy Bower, Daniel Andresen, David Bacon

This paper examines the potential benefits of an extension to the HTTP protocol that allows the web server and client to establish a session of HTTP messages as opposed to a sequence of independent...

The STAGES view of red spirals and dusty red galaxies: Mass-dependent quenching of star-formation in cluster infall (2008)

Wolf, Christian, Aragon-Salamanca, Alfonso, Balogh, Michael, Barden, Marco, Bell, Eric F., Gray, Meghan E., ...

We investigate the properties of optically passive spirals and dusty red galaxies in the A901/2 cluster complex at redshift ~0.17 using restframe near-UV-optical SEDs, 24 micron IR data and HST...

STAGES: the Space Telescope A901/2 Galaxy Evolution Survey (2008)

Gray, M. E., Wolf, Christian, Barden, Marco, Peng, Chien Y., Haeussler, Boris, Bell, Eric F., ...

We present an overview of the Space Telescope A901/2 Galaxy Evolution Survey (STAGES). STAGES is a multiwavelength project designed to probe physical drivers of galaxy evolution across a wide range...

L Acoustic Ray-Tracing on Unstructured Adaptive Grids (2008)

David Bacon, Tom Dunn, Mary Hall, Ananthakrishna Sarma, Tim Wait

A computationally efficient acoustic ray-tracing code based on unstructured adaptive grids is described in detail. The use of unstructured grids allows wave propagation simulations on complex...

The dark matter environment of the Abell 901/902 supercluster: a weak lensing analysis of the HST STAGES survey (2008)

Heymans, Catherine, Gray, Meghan E., Peng, Chien Y., Van Waerbeke, Ludovic, Bell, Eric F., Wolf, Christian, ...

We present a high-resolution dark matter reconstruction of the z = 0.165 Abell 901/902 supercluster from a weak lensing analysis of the Hubble Space Telescope STAGES survey. We detect the four main...

Dark matter maps reveal cosmic scaffolding (2007)

Massey, Richard, Rhodes, Jason, Ellis, Richard, Scoville, Nick, Leauthaud, Alexie, Finoguenov, Alexis, ...

Ordinary baryonic particles (such as protons and neutrons) account for only one-sixth of the total matter in the Universe. The remainder is a mysterious "dark matter" component, which does not...

Dependence of radiation damage accumulation in iron on underlying models of displacement cascades and subsequent defect migration (2006)

Souidi, Abdelkader, Becquart, Charlotte, Domain, Christophe, Terentyev, Dmitry, Malerba, Lorenzo, Calder, Andrew, ...

Groups of displacement cascades calculated independently with different codes and models are compared and used for object kinetic Monte Carlo (OKMC) simulations, in order to check the effect of the...

The Shear Testing Programme - I. Weak lensing analysis of simulated ground-based observations (2006)

Heymans, Catherine, Van Waerbeke, Ludovic, Bacon, David, Berge, Joel, Bernstein, Gary, Bertin, Emmanuel, ...

The Shear Testing Programme (STEP) is a collaborative project to improve the accuracy and reliability of all weak lensing measurements in preparation for the next generation of wide-field surveys. In...

The Shear TEsting Programme, STEP, is a collaborative project to improve the accuracy and reliability of all weak lensing measurements in preparation for the next generation of wide-field surveys. In...

A Small Peptide (CEL-1000) Derived from the ß-Chain of the Human Major Histocompatibility Complex Class II Molecule Induces Complete Protection against Malaria in an Antigen-Independent Manner (2004)

Charoenvit, Yupin, Brice, Gary T., Bacon, David, Majam, Victoria, Williams, Jackie, Abot, Esteban, ...

CEL-1000 (DGQEEKAGVVSTGLIGGG) is a novel potential preventative and therapeutic agent. We report that CEL-1000 confers a high degree of protection against Plasmodium sporozoite challenge in a murine...

A Solution-Adaptive Grid Generation Scheme for Atmospheric Flow Simulations (1998)

David Bacon, Zafer Boybeyi, Thomas Dunn

Science Applications International Corporation (SAIC) has developed a novel hazardous dispersion model with support from the Defense Special Weapons Agency. The Operational Multiscale Environment...

Thin Locks: Featherweight Synchronization for Java (1998)

David Bacon, Ravi Konuru, Chet Murthy, Mauricio Serrano

Language-supported synchronization is a source of serious performance problems in many Java programs. Even singlethreaded applications may spend up to half their time performing useless...
