    We present a measurement of the rate of distant Type la supernovae derived using four large subsets of data from the Supernova Cosmology Project. Within this fiducial sample, which surveyed about 12 deg2, 38 supernovae were detected at redshifts 0.25-0.85. In a spatially flat cosmological model consistent with the results obtained by the Supernova Cosmology Project, we derive a rest-frame Type la supernova rate at a mean redshift z ≃ 0.55 of 1.53-0.25-0.31-0.28-0.32 × 10-4 h 3 Mpc-3 yr-1 or 0.58…Read more

    The state of Parhae (in Chinese reading- Bohai) existed in what is now Russian Maritime region, North Korea and Northeastern China from the late 7th to the early 10th centuries AD. Parhae played a major role at relations between Silla, Japan and Chinese empire Tang. Of course, Parhae was subjected to important cultural influence from other countries and in some cases followed their ritual and diplomatic tradition. Many specialists from Japan, Russia, China and both Korean states have done resear…Read more
