The NANOGrav Nine-Year Data Set: Noise Budget for Pulsar Arrival Times on Intraday Timescales
M. T. Lam, J. M. Cordes, S. Chatterjee +21
The use of pulsars as astrophysical clocks for gravitational wave experiments demands the highest possible timing precision. Pulse times of arrival (TOAs) are limited by stochastic…
Correcting for Interstellar Scattering Delay in High-precision Pulsar Timing: Simulation Results
Nipuni Palliyaguru, Daniel Stinebring, Maura McLaughlin +2
Light travel time changes due to gravitational waves may be detected within the next decade through precision timing of millisecond pulsars. Removal of frequency-dependent interste…
First low frequency all-sky search for continuous gravitational wave signals
The LIGO Scientific Collaboration, the Virgo Collaboration, J. Aasi +921
In this paper we present the results of the first low frequency all-sky search of continuous gravitational wave signals conducted on Virgo VSR2 and VSR4 data. The search covered th…
Single-Source Gravitational Wave Limits from the J1713+0747 24-hr Global Campaign
T. Dolch, J. A. Ellis, S. Chatterjee +34
Dense, continuous pulsar timing observations over a 24-hr period provide a method for probing intermediate gravitational wave (GW) frequencies from 10 microhertz to 20 millihertz.…
The NANOGrav Nine-year Data Set: Observations, Arrival Time Measurements, and Analysis of 37 Millisecond Pulsars
Z. Arzoumanian, A. Brazier, S. Burke-Spolaor +41
We present high-precision timing observations spanning up to nine years for 37 millisecond pulsars monitored with the Green Bank and Arecibo radio telescopes as part of the North A…
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-…
