The NANOGrav 12.5-Year Data Set: Polarimetry and Faraday Rotation Measures from Observations of Millisecond Pulsars with the Green Bank Telescope
Haley M. Wahl, Maura McLaughlin, Peter A. Gentile +28
In this work, we present polarization profiles for 23 millisecond pulsars observed at 820 MHz and 1500 MHz with the Green Bank Telescope as part of the NANOGrav pulsar timing array…
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…
The NANOGrav 11-Year Data Set: Limits on Gravitational Wave Memory
K. Aggarwal, Z. Arzoumanian, P. T. Baker +58
The mergers of supermassive black hole binaries (SMBHBs) promise to be incredible sources of gravitational waves (GWs). While the oscillatory part of the merger gravitational wavef…
The NANOGrav 11-year Data Set: Constraints on Planetary Masses Around 45 Millisecond Pulsars
E. A. Behrens, S. M. Ransom, D. R. Madison +27
We search for extrasolar planets around millisecond pulsars using pulsar timing data and seek to determine the minimum detectable planetary masses as a function of orbital period.…
Tests of Gravitational Symmetries with Pulsar Binary J1713+0747
W. W. Zhu, G. Desvignes, N. Wex +50
Symmetries play an important role in modern theories of gravity. The strong equivalence principle (SEP) constitutes a collection of gravitational symmetries which are all implement…
A Large-Diameter Hollow-Shaft Cryogenic Motor Based on a Superconducting Magnetic Bearing for Millimeter-Wave Polarimetry
B. R. Johnson, F. Columbro, D. Araujo +6
In this paper we present the design and measured performance of a novel cryogenic motor based on a superconducting magnetic bearing (SMB). The motor is tailored for use in millimet…
The NANOGrav Nine-Year Data Set: Excess Noise in Millisecond Pulsar Arrival Times
M. T. Lam, J. M. Cordes, S. Chatterjee +22
Gravitational wave astronomy using a pulsar timing array requires high-quality millisecond pulsars, correctable interstellar propagation delays, and high-precision measurements of…
The NANOGrav Nine-year Data Set: Mass and Geometric Measurements of Binary Millisecond Pulsars
Emmanuel Fonseca, Timothy T. Pennucci, Justin A. Ellis +17
We analyze 24 binary radio pulsars in the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) nine-year data set. We make fourteen significant measurements of S…
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…
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: Limits on the Isotropic Stochastic Gravitational Wave Background
