The NANOGrav 15 yr Data Set: Running of the Spectral Index
Gabriella Agazie, Akash Anumarlapudi, Anne M. Archibald +102
The NANOGrav 15-year data provides compelling evidence for a stochastic gravitational-wave (GW) background at nanohertz frequencies. The simplest model-independent approach to char…

Generators of the Poincaré Group for arbitrary tensors and spinor-tensors
H. V. Almeida Silva, D. Dalmazi, R. R. Lino dos Santos +1
In this work, we systematically derive explicit expressions for the Poincaré Group generators on arbitrary-rank tensors and spinor-tensors in and spacetimes, thus g…

From quantum gravity to gravitational waves through cosmic strings
Astrid Eichhorn, Rafael R. Lino dos Santos, João Lucas Miqueleto
New physics beyond the Standard Model can give rise to stochastic gravitational-wave backgrounds, for example through cosmic strings. In this way, gravitational-wave searches with…
