Ultimate Goals: 

Ultimate Goals Energy Frontier of Particle Physics, Cosmology and Astronomy Earliest Universe: GUT, Planck Scale … Extreme Universe: AGN, GRB … Charged-Particle Astronomy Need for Multi-Messenger Approach Gamma ray Veritas, GLAST … Charged Particle Auger, EUSO … Neutrino Icecube, Auger … Gravitational Wave LIGO, LISA …

The Extreme Universe: 

The Extreme Universe Big Bang

The Extreme Universe: 

The Extreme Universe Pulsar GRB AGN SNR Radio Galaxy

TeV Gamma Rays: 

TeV Gamma Rays ~3% of full sky covered so far.

High Energy Neutrino: 

High Energy Neutrino SN1987A Full sky will covered by AMANDA/Icecube and Antares/Nestor

Gravitational Wave: 

Gravitational Wave Full sky will covered by LIGO and VIRGO

COBE (90MHz): 

COBE (90MHz)

WMAP (W-Band): 

WMAP (W-Band)

Why All Sky Coverage?: 

Why All Sky Coverage? Multi-pole Moment Analysis Isotropic Cosmological Origin Dipole Galactic Halo Quadra-pole Local Super-cluster Origin of Point Sources Galactic vs. Extra Galactic Within GZK-sphere vs. Cosmological

Why North?: 

Why North? Need to verify “AGASA” point-sources on North. Need to verify discrepancy of “AGASA” vs. “HiRes” spectrum on North. Important to see outside of the Galactic plane, where B-field is weak and uniform.

Why Hybrid?: 

Why Hybrid? Charged particle Astronomy between Ankle and GZK-cutoff Statistics is high enough. Need <1o angular resolution for momentum analysis. Need superior composition measurements.

Energy Spectrum of Cosmic Rays: 

Energy Spectrum of Cosmic Rays Knee Ankle ? E-2.7 E-3.1 E-2.7 Galactic Extra Galactic ?

Why Timely ?: 

Why Timely ? It is timely for “Multi-messenger” exploration of the “Extreme Universe”. Gamma Rays Veritas, Hess, Magic … GLAST, Swift Neutrinos AMANDA, ICECUBE ANTARES, NESTOR Gravitational Waves LIGO, VIRGO LISA
