Yann Gouttenoire |
| In this talk, I will give an overview of my past research and outline my future program as a CNRS researcher. A central question motivating this work is the origin of the nano-Hertz gravitational wave signal reported in 2023 by Pulsar Timing Arrays collaborations. I will discuss how primordial black holes and small-scale dark matter structure can offer promising avenues to disentangle the primordial and astrophysical contributions to this signal. |
