I came across the "Suspicious Observers" YT channel a few weeks ago. This channel deals with the overall idea that Earth cyclical cataclysms are the results of a combination of our galaxy current sheet and our Sun cyclically becoming a "micro-nova".
Ben Davidson's book "The Next End of the World: The Rebirth of Catastrophism" (2021) is available here
The videos on YT provide plenty of links toward recent academic studies that deals with the magnetic excurcion and micronova phenomena.
Thought this might be of interest for you and your readers,
