A Radio SETI Campaign for microsec-sec Periodic Signals
...Published in arXiv preprint arXiv:1506.00055
We report a novel radio autocorrelation (AC) search for extraterrestrial intelligence (SETI). For selected frequencies across the terrestrial microwave window (1-10 GHz) observations were conducted at the Allen Telescope Array to identify artificial non-sinusoidal periodic signals with radio bandwidths greater than 1 kHz, which are capable of carry...
Co/Pt MULTILAYERS
Published in Magnetism and Structure in Systems of Reduced Dimension
In this paper we report the results of a synchrotron X-ray diffraction study of epitaxial,[111]-oriented Co/Pt multilayers which demonstrates the existence of interfacial mixing and extensive chemical ordering in the multilayers. We also report new magnetic data for epitaxial Coſpt multilayers, grown along the 3 major axes:[111],[110] and [001], wh...
Beings on Earth: Is That All There Is?
Published in Proceedings of the IEEE
| The systematic search for extraterrestrial intelligence (SETI) has been ongoing for slightly more than half the century that this journal has been in print, and the topic has been of human interest through recorded history. Are we any closer to detecting cosmic company or knowing whether it should be there? This paper takes a look at what has bee...

Customized Beam Forming at the Allen Telescope Array (August 11, 2002)
Published in arxiv
One of the exciting prospects for large N arrays is the potential for custom beam forming when operating in phased array mode. Pattern nulls may be generated by properly weighting the signals from all antennas with only minor degradation of gain in the main beam. Here we explore the limits of beam shape manipulation using the parameters of the Alle...

Commensal observing with the Allen Telescope array: software command and control
The Allen Telescope Array (ATA) is a Large-Number-Small-Diameter radio telescope array currently with 42 individual antennas and 5 independent back-end science systems (2 imaging FX correlators and 3 time domain beam formers) located at the Hat Creek Radio Observatory (HCRO). The goal of the ATA is to run multiple back-ends simultaneously, supporti...
