Space Public Outreach Team: Successful STEM Engagement on Complex Technical Topics
Angela Des Jardins, Joey Shapiro Key, Kathryn Williamson +5
It is the responsibility of today's scientists, engineers, and educators to inspire and encourage our youth into technical careers that benefit our society. Too often, however, thi…
The NANOGrav 12.5-year Data Set: Search For An Isotropic Stochastic Gravitational-Wave Background
Zaven Arzoumanian, Paul T. Baker, Harsha Blumer +58
We search for an isotropic stochastic gravitational-wave background (GWB) in the -year pulsar timing data set collected by the North American Nanohertz Observatory for Gravit…
Multi-Messenger Gravitational Wave Searches with Pulsar Timing Arrays: Application to 3C66B Using the NANOGrav 11-year Data Set
Zaven Arzoumanian, Paul T. Baker, Adam Brazier +56
When galaxies merge, the supermassive black holes in their centers may form binaries and, during the process of merger, emit low-frequency gravitational radiation in the process. I…
The NANOGrav 12.5-year Data Set: Wideband Timing of 47 Millisecond Pulsars
Md F. Alam, Zaven Arzoumanian, Paul T. Baker +67
We present a new analysis of the profile data from the 47 millisecond pulsars comprising the 12.5-year data set of the North American Nanohertz Observatory for Gravitational Waves…
The NANOGrav 12.5 yr Data Set: Observations and Narrowband Timing of 47 Millisecond Pulsars
Md F. Alam, Zaven Arzoumanian, Paul T. Baker +67
We present time-of-arrival (TOA) measurements and timing models of 47 millisecond pulsars (MSPs) observed from 2004 to 2017 at the Arecibo Observatory and the Green Bank Telescope…
Modeling the uncertainties of solar-system ephemerides for robust gravitational-wave searches with pulsar timing arrays
M. Vallisneri, S. R. Taylor, J. Simon +61
The regularity of pulsar emissions becomes apparent once we reference the pulses' times of arrivals to the inertial rest frame of the solar system. It follows that errors in the de…
