Cov txiaj ntsig ntawm kev txhais lus tau hais tias yog vim muaj cov khoom tsim positron hauv kev rhuav tshem cov xwm txheej ntawm cov teeb meem tsaus ntuj loj heev. Cosmic ray antiprotons kuj tseem muaj lub zog nruab nrab ntau dua li lawv cov khoom sib xws (protons).
Daim duab ntawm cosmic ray twg muaj lub zog siab tshaj?
PeVatrons tau ntseeg tias yog qhov chaw muaj zog tshaj plaws ntawm cosmic rays hauv peb lub galaxy, thiab lawv qhov kev txheeb xyuas tseeb tau dhau los ua qhov nyuaj. PeVatrons ceev cov protons rau petaelectronvolts (PeVs), ib qho loj ntawm lub zog kinetic muaj peev xwm ntawm slinging subatomic hais teeb-xyoo thoob plaws galaxy.
Lub zog npaum li cas hauv lub cosmic ray?
Lub zog ntawm thawj cosmic rays muaj los ntawm ncig 1 GeV - lub zog ntawm cov khoom siv me me - kom ntau li 10 8TeV, deb tshaj qhov nqaj zog ntawm Loj Hadron Collider.
Dab tsi yog qhov hluav taws xob siab tshaj plaws?
Gamma-rays yog daim ntawv muaj zog tshaj plaws ntawm hluav taws xob hluav taws xob, nrog ntau dua 10,000 npaug zog dua li pom lub teeb photons. Yog tias koj pom Gamma-rays, lub ntuj hmo ntuj yuav zoo li txawv txawv thiab tsis paub.
Yuav ua li cas lub cosmic rays siv rau lub zog?
Cov xwm txheej tseem ceeb tshaj plaws hauv qhov chaw yog hnub ci cua thiab galactic cosmic rays. Cov xwm txheej no ntws tawm cov khoom muaj zog heev xws li proton, electron, alphaparticle thiab HZE. Lub zog muaj los ntawm proton thiab electron feem ntau yog nruab nrab ntawm 1.5 thiab 10 keV. Lub zog no siv tau los tsim hluav taws xob.
