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…
Statistical Analyses for NANOGrav 5-year Timing Residuals
Y. Wang, J. M. Cordes, F. A. Jenet +11
In pulsar timing, timing residuals are the differences between the observed times of arrival and the predictions from the timing model. A comprehensive timing model will produce fe…
An Einstein@home search for continuous gravitational waves from Cassiopeia A
Sylvia J. Zhu, Maria Alessandra Papa, Heinz-Bernd Eggenstein +9
We report the results of a directed search for continuous gravitational-wave emission in a broad frequency range (between 50 and 1000 Hz) from the central compact object of the sup…
Supermassive Black Hole Binary Environments: Effects on the Scaling Laws and Time to Detection for the Stochastic Background
Sarah J. Vigeland, Xavier Siemens
One of the primary gravitational wave (GW) sources for pulsar timing arrays (PTAs) is the stochastic background formed by supermassive black holes binaries (SMBHBs). In this paper,…
Hierarchical follow-up of sub-threshold candidates of an all-sky Einstein@Home search for continuous gravitational waves on LIGO sixth science run data
Maria Alessandra Papa, Heinz-Bernd Eggenstein, Sinéad Walsh +12
We report results of an all-sky search for periodic gravitational waves with frequency between 50 and 510 Hz from isolated compact objects, i.e. neutron stars. A new hierarchical m…
Timing of Five PALFA-Discovered Millisecond Pulsars
K. Stovall, B. Allen, S. Bogdanov +32
We report the discovery and timing results for five millisecond pulsars (MSPs) from the Arecibo PALFA survey: PSRs J1906+0055, J1914+0659, J1933+1726, J1938+2516, and J1957+2516. T…
