Could This Particle 'Clean Up' A Cosmic Mystery?

So the short answer is this is not a particle that you go looking for by smashing things together. And there's a little bit of potential there, but because of how this particle... So let me think about how we would say this. So the way that we would say this is... in physicist speak, is that the particle doesn't couple very strongly to standard model particles.

And so when you are colliding particles together and looking for other particles, that assumes that there is such a strong relationship between those particles and whatever you're trying to create that it will pop out when you smash them together. But if that relationship doesn't really exist in the first place, there's no amount of smashing together that's going to that's going to make it happen.

It's not going to work. You're not going to make fetch happen. That's so you just like you don't make axions happen that way. She doesn't even go here. She doesn't even go here. That's exactly it. She doesn't even go here.

So this is where computation can be really useful. And so you can imagine a scenario where there are two galaxies that are maybe colliding with each other and basically collided them to see what would happen. And then we tweaked the properties of the axion-like particle to see if the collision happened differently depending on how we tweaked the properties.

And so this is an example of why you would call it, for example, particle cosmology, because this is one where we're making changes to the characteristics of a very small object. But then we're looking at large scale astrophysical implications for those very small changes that we make. Oh, that's so cool.

Yeah, so neutron stars, just to back up a little bit, neutron stars are stellar remnants. So they are objects that are formed when a massive star reaches the end of its life, goes through a supernova experience, and neutron star is potentially left over on the other end. So this is not well understood, but neutron stars often have a magnetic field associated with them.

And when I say it's not well understood, we don't really understand where the magnetic field comes from. There are good models for it, but this is actually still an active area of research. So I made this claim that dark matter doesn't really interact with light, but axions do actually have a very mild, tiny, tiny, tiny interaction with light.
