Noncommutative Spacetime Realized in Space
S. Naka, H. Toyoda, T. Takanashi +1
In -Minkowski spacetime, the coordinates are Lie algebraic elements such that time and space coordinates do not commute, whereas space coordinates commute each other. The non-co…
Search for VHE gamma rays from SS433/W50 with the CANGAROO-II telescope

CANGAROO-III Search for Gamma Rays from SN 1987A and the Surrounding Field
R. Enomoto
Optical images of SN 1987A show a triple ring structure. The inner (dust) ring has recently increased in brightness and in the number of hot spots suggesting that the supernova sho…

R. Enomoto, S. Watanabe, T. Tanimori et al
Sub-TeV gamma-ray emission from the North-West rim of the supernova remnant RX J0852.04622 was detected with the CANGAROO-II telescope and recently confirmed by the H.E.S.S. gro…
Sp(4,H)/Z_2 Pair Universe in E6 Matrix Models
Yuhi Ohwashi
We construct interacting Sp(4,H)/Z_2 pair matrix models inside the compact E6 matrix models. Generally, models based on the compact E6 seem to always include doubly the degrees of…
