My talk focuses on using Pulsar Timing Array (PTA) data to measure Gravitational Waves (GWs). In particular, I will focus on Stochastic GW Background (SGWB) measurements. After a general introduction to the topic, I will discuss a new methodology to constrain SGWBs with PTA data. This approach leads to a significant gain in the run time, allowing us to forecast the constraining power of future PTA experiments at very low computational cost.
