Commissioning the HI Observing Mode of the Beamformer for the Cryogenically Cooled Focal L-band Array for the GBT (FLAG)
N. M. Pingel, D. J. Pisano, M. Ruzindana +19
We present the results of commissioning observations for a new digital beamforming back end for the Focal plane L-band Array for the Robert C. Byrd Green Bank Telescope (FLAG), a c…
Calibration of Argus and the 4mm Receiver on the GBT
David T. Frayer, Ronald J. Maddalena, Steven White +4
The calibration procedures for data collected for Argus and the 4mm Receiver instruments on the GBT are presented. The measured beam size, aperture efficiency, and main-beam effici…
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 GBT 67 -- 93.6 GHz Spectral Line Survey of Orion-KL
D. T. Frayer, Ronald J. Maddalena, M. Meijer +14
We present a 67--93.6 GHz spectral line survey of Orion-KL with the new 4 mm Receiver on the Green Bank Telescope (GBT). The survey reaches unprecedented depths and covers the low-…
