The NANOGrav 15 yr Data Set: Chromatic Gaussian Process Noise Models for Six Pulsars

Bjorn Larsen, Chiara M. F. Mingarelli, Jeffrey S. Hazboun +61

Pulsar timing arrays (PTAs) are designed to detect low-frequency gravitational waves (GWs). GWs induce achromatic signals in PTA data, meaning that the timing delays do not depend…
