Workshop Scope and Goals: The detection of Gravitational Waves has opened a new window to observe the universe. The evidence of a stochastic gravitational wave background (SGWB) found by Pulsar Timing Arrays (PTAs) such as the NANOGrav Collaboration gives a view of the SGWB in the nanohertz frequency range. At the same time, significant progress has been made in understanding the primordial and astrophysical sources of gravitational waves and their detection with PTAs. Thus PTAs can provide a window into the astrophysics of supermassive black holes (SMBH), as well as beyond standard model physics that could have played a role during the first microseconds of the universe. The aim of this workshop is to bring experts on various topics of PTAs, astrophysics of SMBH, and primordial sources of gravitational waves. It will focus on opportunities for pulsars and PTAs to address problems in astronomy, astrophysics and BSM physics. Plenty of time will be provided to foster collaboration among the participants.
