Can a combination of the conformal thin-sandwich and puncture methods yield binary black hole solutions in quasi-equilibrium? (2003)

Hannam, Mark D., Evans, Charles R., Cook, Gregory B., Baumgarte, Thomas W.

We consider combining two important methods for constructing quasi-equilibrium initial data for binary black holes: the conformal thin-sandwich formalism and the puncture method. The former seeks to...

The SOAR Telescope Project Southern Observatory for Astronomical Research (SOAR) (1998)

Evans, Charles R., Clemens, J. C.

This document is the final report on progress in constructing the SOAR telescope. SOAR has been built with partial support from an AFRL grant (F29601-98-l-0032) to the University of North Carolina....

Do OB Runaway Stars Have Pulsar Companions? (1995)

Philp, Colin J., Evans, Charles R., Leonard, Peter J. T., Frail, Dale A.

We have conducted a VLA search for radio pulsars at the positions of 44 nearby OB runaway stars. The observations involved both searching images for point sources of continuum emission and a time...

Observation of critical phenomena and self-similarity in the gravitational collapse of radiation fluid (1994)

Evans, Charles R., Coleman, Jason S.

We observe critical phenomena in spherical collapse of radiation fluid. A sequence of spacetimes $\cal{S}[\eta]$ is numerically computed, containing models ($\eta\ll 1$) that adiabatically disperse...
