SUMMARY:STUDIES OF GALACTIC COSMIC RAYS WITH DIRECT AND INDIRECT MEASU
 REMENTS\, NPAC (Nuclear/Particle/Astro/Cosmo) Forum\, Nahee Park\, Uni
 versity of Chicago
DESCRIPTION:Cosmic rays\, high energy particles originating from outsi
 de of the solar system\, are believed to be dominated by particles fro
 m our Galaxy at least up to the energy of 1015 eV. Recent results from
  direct measurements of cosmic rays\, including the rise of the positr
 on flux\, the hardening of the light nuclei\, and the different spectr
 al indexes of the proton and helium spectra\, challenge the classical 
 models of the Galactic cosmic rays. Meanwhile\, the development of gam
 ma-ray experiments has opened a new window to study the acceleration a
 nd propagation of high-energy particles in the vicinity of the source 
 sites\, such as supernova remnants.<br>
\n<br>
\nI will introduce HELI
 X (High Energy Light Isotope eXperiment)\, a near-future balloon-borne
  experiment designed to improve our understanding of the propagation o
 f Galactic cosmic rays by measuring the key clock isotope 10Be up to 1
 0 GeV/n. I will also present the Galactic gamma-ray measurements from 
 the VERITAS experiment\, an imaging atmospheric Cherenkov telescope me
 asuring gamma rays with energies higher than 85 GeV and up to ~ 30 TeV
 . Focusing on the supernova remnants\, I will discuss what we have lea
 rned about the acceleration of high-energy particles and what we expec
 t to learn in the near future. Finally\, I will highlight how neutrino
  observations with IceCube\, in coordination with gamma-ray and cosmic
 -ray direct measurements\, will broaden our perspective on the product
 ion and propagation of high-energy particles and advance us toward a n
 ew paradigm of Galactic cosmic rays.
