We didn’t see any gammas from the source and can conclude that the AGN in question probably isn’t emitting neutrinos or that maybe the way it’s doing it is something different from what we currently understand. We did detect a bunch of X-rays from the source for the first time though, which is cool!

So anyway, we got an alert from IceCube saying that a bunch of neutrinos were coming from a known gamma-ray source and we got excited. Pinpointing neutrino sources is also important because we don’t get a lot of neutrinos so it’s hard to tell where they come from

We can’t directly trace cosmic rays back to their birthplaces because they get spun off by magnetic fields (since they’re charged but gammas and neutrinos aren’t, so they’ll point right back to where they came from)

We think that gamma-rays and neutrinos of pretty high energies might be made in the same place — this is important because it would be a smoking gun signal for cosmic rays also being made in these places

Hi! I’m a physics phd student orcid.org/0000-0002-27...

i like just getting the email digest! very low tech but easy to quickly read through all the abstracts

I always make homemade vegetarian pierogis — a bit time consuming but I grew up on polish Christmas dinner and they’re sooooo good
