Including millisecond pulsars inside the core of globular clusters in pulsar timing arrays

We suggest the possibility of including millisecond pulsars inside core globular clusters in pulsar timing array experiments. Since they are very close to each other, their gravitational wave-induced residuals expected be almost same, because both Earth and terms correlated. simulate residuals, due wave signal emitted by a uniform supermassive black-hole binary population, on cluster core. In this respect, Terzan 5 has been adopted as prototype and, our simulations, we similar distance, radius, number contained it. Our results show that presence strong correlation between can provide remarkable signature. This result therefore exploited for detection waves through timing, especially conjunction with standard cross-correlation search carried out collaborations.
