back to article A high-energy neutrino, a powerful cosmic ray, and a gamma ray walk into a bar... Where you from, asks the bartender

A new model has traced the origins of high-energy neutrinos, cosmic rays, and gamma rays to powerful jets billowing around supermassive black holes. Known as cosmic messenger particles, these neutrinos and rays carry huge amounts of energy, travel insane distances across space, and can be detected when they reach Earth – yet …

    Sure, says the steward, can I take your luggage?

    No thanks, says the photon, I'm travelling light.

    these neutrinos and rays carry huge amounts of energy,

    Probably me being a bit dim, but if the amounts of energy are "huge", why on earth (literally) are neutrinos so hard to find ?

    Not going A/C, as I'm not ashamed to ask the question.

      Re: these neutrinos and rays carry huge amounts of energy,

      It's a good question, neutrinos are everywhere and can carry a large amount of energy, but they don't carry electrical charge and only interact via the weak nuclear force (and gravity) unlike electrons (carry electrical charge) and quarks (electrical charge and strong nuclear force). This is sometimes expressed as having a tiny interaction cross section (the area one needs to pass through to be affected by another particle). The result is billions of neutrinos originating in the sun pass through you every second https://en.wikipedia.org/wiki/Neutrino#Solar

      Finding is easy, they're everywhere, but catching them for analysis is very hard. Those buggers can slip through most obstacles without giving a pause.

    screaming coincidence.

    Having chewed through "Evolution - the story of life" for bedtime reading (for the third time) last year, the youngest switched to "We Have No Idea" (Whiteson/Cham) at the beginning of this year, and we hit 'cosmic rays' section on Friday - discussed this on Sunday night. I suppose this sort of stuff might seem a bit heady for an 11/12 year old but it is *fun* letting their imagination run wild on stuff like this. The book is a *great* read for anyone interested in physics. And lamas.

    I did need to dig a bit, as the discussion of "cosmic rays" alongside fundamental particles (neutrinos and gamma) was a bit confusing and the original paper doesn't help. It turns out "cosmic ray" means it has mass (no-one tell them about the neutrinos!), very high energy and comes from space, so anything up to the size of a nucleus (rocks don't count).

      btw

      Cosmic rays are high energy radiation from space. It is often used purely for the massive particles (which includes neutrinos, btw), but not always and it's a relatively recent distinction in any case. The particles need not be fundamental either - nuclei up to and including iron are found in the flux (esp. for E < ~10^15eV)

      It is virtually always used to mean particles with E>10^12eV, since below that energy, the flux of extra-solar particles is completely swamped by the solar wind.

        Exactly: if not solely for massive particles then it includes photons (there aren't many other massless ones we can detect), so the story becomes, "cosmic rays have similar energy to other cosmic rays of similar energy". Knowing they are making an unstated distinction for nuclei separate to neutrinos and gamma is rather crucial to understand what's going on.

          Re: btw

          I see what you mean, but the researcher talks about the intensities being similar.

          “The fact that the measured intensities of very high-energy neutrinos, ultrahigh-energy cosmic rays, and high-energy gamma rays are roughly comparable tempted us to wonder if these extremely energetic particles have some physical connections.”

          Logically, the intensity of <generic_cosmic_radiation> can't be the same as intensity of <generic_cosmic_radiation> + intensity of gamma + intensity of neutrinos unless there's no flux of neutrinos and gamma at all*. Hence he *must* be using the specific context.

          OTOH, it's a good old while since I was involved in CR research - maybe the distinction is always made nowadays... :-)

    Two men walk into a bar, the third ducks.

    Maybe I am missing something, but I had kind of always thought this was already a well accepted theory / known / assumed. I guess it's nice that they spent piles of money to play with big electromagnets in order to still not quite really prove it? I guess I need to walk into their bar for this to all make sense as being newsworthy. (Or interesting.)
