This question touches on the known and theoretical...

Are there any particles or emissions, however faint, known or theorized,
that would allow a sufficiently sensitive sensor to detect a nuclear
detonation (actually, enough to destroy all civilization on a world of
~7+ billion people in a day) at interstellar distances either as it
happened or within a short (less than a week or so) period of time?

My gut says no, but with mesons and other goodies that are on the
bleeding edge, I figured I'd ask and see what the hive has to say.

Thanks!
