Reaching diffraction-limited localization with coherent PTAs
Anna C. Tsai, Dylan L. Jow, Ue-Li Pen
Current pulsar timing array (PTA) analyses do not take full advantage of pulsar distance information, thereby missing out on improved angular resolution and on a potential factor-o…

How many pixels are there in a polarized pulsar timing array map?
Dylan L. Jow, Anna Tsai, Ue-Li Pen
The standard approach to searching for gravitational wave signatures in pulsar timing array (PTA) data has been to compare the theoretical Hellings and Downs (HD) curve with the ob…

Scintillated microlensing: measuring cosmic distances with fast radio bursts
Anna Tsai, Dylan L. Jow, Daniel Baker +1
We propose a novel means of directly measuring cosmological distances using scintillated microlensing of fast radio bursts (FRBs). In standard strong lensing measurements of cosmic…
