Searching for continuous gravitational wave signals: the hierarchical Hough transform algorithm
M. A. Papa, B. F. Schutz, A. M. Sintes
It is well known that matched filtering techniques cannot be applied for searching extensive parameter space volumes for continuous gravitational wave signals. This is the reason w…
Removing Line Interference from Gravitational Wave Interferometer Data
A. M. Sintes, B. F. Schutz
We describe a procedure to identify and remove a class of interference lines from gravitational wave interferometer data. We illustrate the usefulness of this technique applying it…
Self-similar perfect fluids
J. Carot, A. M. Sintes
Space-times admitting an -parameter Lie group of homotheties are studied for devoting a special attention to those representing perfect fluid solutions to Einstein's fie…
Perfect fluid space-times admitting a 3-dimensional conformal group acting on null orbits
A. M. Sintes, J. Carot
Space-times admitting a 3-dimensional Lie group of conformal motions acting on null orbits are studied. Coordinate expressions for the metric and the conformal Killing vector…
On space-times admitting shear-free, irrotational, geodesic null congruences
A. M. Sintes, A. A. Coley, D. J. McManus
Space-times admitting a shear-free, irrotational, geodesic null congruence are studied. Attention is focused on those space-times in which the gravitational field is a combination…
Removal of interference from external coherent signals
A. M. Sintes, B. F. Schutz
We present a technique that we call coherent line removal, for removing external coherent interference from gravitational wave interferometer data. We illustrate the usefulness of…
