Liam K Hardy, Vik S Dhillon, Laura G Spitler +14
We present a search for optical bursts from the repeating fast radio burst FRB 121102 using simultaneous observations with the high-speed optical camera ULTRASPEC on the 2.4-m Thai…
Pulsar Timing and its Application for Navigation and Gravitational Wave Detection
Werner Becker, Michael Kramer, Alberto Sesana
Pulsars are natural cosmic clocks. On long timescales they rival the precision of terrestrial atomic clocks. Using a technique called pulsar timing, the exact measurement of pulse…
The noise properties of 42 millisecond pulsars from the European Pulsar Timing Array and their impact on gravitational wave searches
R. N. Caballero, K. J. Lee, L. Lentati +36
The sensitivity of Pulsar Timing Arrays to gravitational waves depends on the noise present in the individual pulsar timing data. Noise may be either intrinsic or extrinsic to the…
