Some of the SKAO Science Book Chapters (“Advancing Astrophysics with the SKA II”) have appeared on the arXiv recently, with an overview given at the link below.
Unfortunately, the links in that document do not currently work, and you have to search for the publications manually.
I have contributed to two publications:
The Astrophysics of Fast Radio Bursts
Understanding Pulsar Magnetospheres with the SKAO
Other group members have been part of:
A Square Kilometre Array Pulsar Census
Exploring the Galactic Plasma with Pulsars in the SKA Era
Discovering and Characterising Exoplanets and Ultracool Dwarfs with the Square Kilometre Array
