Pulsar Timing ArraysNear FutureInstrumentationReceiver performancereaching fundamentallimits, e.g.,• T sys ≈ 20 K• ∆ν ~ 1 GHz forobservations near 1 GHzNew Pulsars• Major radio pulsarsurveys worldwide– HTRU (Parkes)– GBNCC (GBT)– GBT drift scan (GBT)– P-ALFA (Arecibo)• Multi-wavelength MSPsa.k.a. Fermi
Pulsar Surveysa “position” on the sky• New pulsars– Add more arms to PTA,increase sensitivity; or– For fixed amount ofobserving time, improvequality of PTA• Survey algorithm1. Observe position on sky2. Search resulting timeseries for periodic signal atperiod P with dispersionDM, with orbitalparameters– Loop
