Skynet Algorithm for Single-Dish Radio Mapping I: Contaminant-Cleaning, Mapping, and Photometering Small-Scale Structures

J. R. Martin, D. E. Reichart, D. A. Dutton +22

We present a single-dish mapping algorithm with a number of advantages over traditional techniques. (1) Our algorithm makes use of weighted modeling, instead of weighted averaging,…

Non-Detection of HCN toward TMC-1: Constraining the Chemistry of Large Carbon-Chain Molecules

Ryan A. Loomis, Christopher N. Shingledecker, Glen Langston +8

Bell et al. (1997) reported the first detection of the cyanopolyyne HCN toward the cold dark cloud TMC-1; no subsequent detections have been reported toward any source. Addi…

A 1.1 to 1.9 GHz SETI Survey of the Kepler Field: I. A Search for Narrow-band Emission from Select Targets

Andrew P. V. Siemion, Paul Demorest, Eric Korpela +8

We present a targeted search for narrow-band (< 5 Hz) drifting sinusoidal radio emission from 86 stars in the Kepler field hosting confirmed or candidate exoplanets. Radio emission…
