Results for the International Pulsar Timing Array Second Mock Data Challenge: New Techniques and Challenges for the Detection of Low-Frequency Gravitational-Wave Signals
P. T. Baker, P. R. Brook, W. C. Fiore +5
We present a detailed analysis of the International Pulsar Timing Array (IPTA) Second Mock Data Challenge. We tested our analysis methods using the open datasets, and then analyzed…
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.…
A pulsar-based timescale from the International Pulsar Timing Array
G. Hobbs, L. Guo, R. N. Caballero +56
We have constructed a new timescale, TT(IPTA16), based on observations of radio pulsars presented in the first data release from the International Pulsar Timing Array (IPTA). We us…
Analysis of Multi-Hour Continuous Observations of Seven Millisecond Pulsars
Brent J. Shapiro-Albert, Maura A. McLaughlin, Michael T. Lam +2
Precision pulsar timing can be used for a variety of astrophysical tests from the detection of gravitational waves to probing the properties of the interstellar medium (ISM). Here…
A Deep Targeted Search for Fast Radio Bursts from the Sites of Low-Redshift Short Gamma-Ray Bursts
D. R. Madison, D. Agarwal, K. Aggarwal +11
Some short gamma-ray bursts (SGRBs) are thought to be caused by the mergers of binary neutron stars which may sometimes produce massive neutron star remnants capable of producing e…
