Noise Budget and Interstellar Medium Mitigation Advances in the NANOGrav Pulsar Timing Array
T. Dolch, S. Chatterjee, J. M. Cordes +9
Gravitational wave (GW) detection with pulsar timing arrays (PTAs) requires accurate noise characterization. The noise of our Galactic-scale GW detector has been systematically eva…
A Second Chromatic Timing Event of Interstellar Origin toward PSR J1713+0747
M. T. Lam, J. A. Ellis, G. Grillo +34
The frequency dependence of radio pulse arrival times provides a probe of structures in the intervening media. Demorest et al. 2013 was the first to show a short-term (~100-200 day…
Optimal Frequency Ranges for Sub-Microsecond Precision Pulsar Timing
M. T. Lam, M. A. McLaughlin, J. M. Cordes +2
Precision pulsar timing requires optimization against measurement errors and astrophysical variance from the neutron stars themselves and the interstellar medium. We investigate op…
