Power Beaming Leakage Radiation as a SETI Observable [Replacement]
The most observable leakage radiation from an advanced civilization may well be from the use of power beaming to transfer energy and accelerate spacecraft. Applications suggested for power beaming...
View ArticleA polyphase filter for many-core architectures [Replacement]
In this article we discuss our implementation of a polyphase filter for real-time data processing in radio astronomy. We describe in detail our implementation of the polyphase filter algorithm and its...
View ArticleBayesian Redshift Classification of Emission-line Galaxies with Photometric...
We present a Bayesian approach to the redshift classification of emission-line galaxies when only a single emission line is detected spectroscopically. We consider the case of surveys for high-redshift...
View ArticleMission to the Gravitational Focus of the Sun: A Critical Analysis
The gravitational field of the sun will focus light from a distant source to a focal point at a minimal distance of 500 Astronomical Units from the sun. A proposed mission to this gravitational focus...
View ArticleUnderstanding the LIGO GW150914 event
We present a simplified method for the extraction of meaningful signals from Hanford and Livingstone 32 seconds data for the GW150914 event made publicly available by the LIGO collaboration and...
View ArticleDo siblings always form and evolve simultaneously? Testing the coevality of...
Multiplicity is common in field stars and among protostellar systems. Models suggest two paths of formation: turbulent fragmentation and protostellar disk fragmentation. We attempt to find whether or...
