DESCRIPTION:High-energy neutrinos and gamma rays as tracers of cosmic-ray a
 cceleration sites - Marcos Santander (Columbia University/Nevis Labs)

A c
 entury of research on cosmic rays has revealed many of the fundamental pro
 perties of these energetic particles\, such as their chemical composition 
 and energy spectrum. The sources of cosmic rays\, however\, remain unknown
 . The discovery of a flux of high-energy astrophysical neutrinos by the Ic
 eCube observatory in 2013 may hold the key to solving this enduring questi
 on. High-energy neutrinos\, as well as gamma rays\, are produced in hadron
 ic cosmic-ray interactions occurring at their source or during propagation
 . While no neutrino source has been identified so far\, the sensitivity of
  these studies can be increased by searching for gamma-ray counterparts in
  temporal and spatial correlation with the IceCube neutrino events. The de
 tection of gamma-ray emission in coincidence with an astrophysical neutrin
 o would represent a smoking-gun signature of a cosmic-ray production site 
 and potentially reveal details about the acceleration medium. In this talk
  I will present the status and recent results from the neutrino follow-up 
 program of the VERITAS observatory\, an air-Cherenkov telescope array in s
 outhern Arizona USA dedicated to gamma-ray astronomy in the very-high-ener
 gy range (VHE\, E > 100 GeV). I will also describe prospects for neutrino 
 follow-up observations using the Cherenkov Telescope Array\, a next-genera
 tion VHE gamma-ray instrument.
