Millisecond Cadence Radio Frequency Interference Filters
Joseph W. Kania, Kevin Bandura, Duncan R. Lorimer +1
Radio Frequency Interference (RFI) greatly reduces sensitivity of radio observations to astrophysical signals and creates false positive candidates in searches for radio transients…
Green Bank Telescope: Overview and analysis of metrology systems and pointing performance
E. White, F. D. Ghigo, R. M. Prestage +7
With a 100mx110m off-axis paraboloid dish, the Green Bank Telescope (GBT) is the largest fully steerable radio telescope on Earth. A major challenge facing large ground-based radio…
An International Survey of Front-End Receivers and Observing Performance of Telescopes for Radio Astronomy
P. Bolli, A. Orfei, A. Zanichelli +18
This paper presents a survey of microwave front-end receivers installed at radio telescopes throughout the World. This unprecedented analysis was conducted as part of a review of f…
Performance of a highly sensitive, 19-element, dual-polarization, cryogenic L-band Phased Array Feed on the Green Bank Telescope
D. Anish Roshi, W. Shillue, B. Simon +26
A new 1.4 GHz 19-element, dual-polarization, cryogenic phased array feed (PAF) radio astronomy receiver has been developed for the Robert C. Byrd Green Bank Telescope (GBT) as part…
A Highly-Sensitive Cryogenic Phased Array Feed for the Green Bank Telescope
D. Anish Roshi, W. Shillue, J. R. Fisher +15
In this paper, we describe the development of a new L-band (1.4 GHz) Cryogenic Phased Array Feed (PAF) system, referred to as the GBT2 array. Results from initial measurements made…
The General Single-Dish Data Format: A Retrospective
Tim Jenness, Elizabeth B. Stobie, Ronald J. Maddalena +5
The General Single-Dish Data format (GSDD) was developed in the mid-1980s as a data model to support centimeter, millimeter and submillimeter instrumentation at NRAO, JCMT, the Uni…
A GPU-Based Wide-Band Radio Spectrometer
Jayanth Chennamangalam, Simon Scott, Glenn Jones +9
The Graphics Processing Unit (GPU) has become an integral part of astronomical instrumentation, enabling high-performance online data reduction and accelerated online signal proces…
Holographic Measurement and Improvement of the Green Bank Telescope Surface
Todd R. Hunter, Frederic R. Schwab, Steven D. White +11
We describe the successful design, implementation, and operation of a 12 GHz holography system installed on the Robert C. Byrd Green Bank Telescope (GBT). We have used a geostation…
Measuring and Correcting Wind-Induced Pointing Errors of the Green Bank Telescope Using an Optical Quadrant Detector
Paul Ries, Todd R. Hunter, Kim T. Constantikes +6
Wind-induced pointing errors are a serious concern for large-aperture high-frequency radio telescopes. In this paper, we describe the implementation of an optical quadrant detector…
