Probing the Equation of State of the Dark Energy with Supernovae

最近观测结果的趋同使宇宙学家得出了令人惊讶的结论：宇宙不仅在膨胀，而且膨胀的速度也在加快。这可以被认为是真空区域之间的反重力。目前，宇宙似乎受到这一神秘暗能量引力效应的支配。遥远的超新星(正在爆炸的恒星)提供了一种绘制宇宙膨胀历史的方法，并可以用来区分驱动加速膨胀的物理学的不同场景。该项目将探测和监测200多颗超新星，以检验暗能量性质的不同假说。

AST-0206329StubbsA recent convergence of observational results has led cosmologists to the surprising conclusion that not only is the Universe expanding, but that the rate of expansion is increasing. This can be thought of as anti-gravity between regions of the vacuum. It appears that the Universe at present is dominated by the gravitational effect of this mysterious Dark Energy. Distant supernovae (exploding stars) provide a means to map out the history of the expansion of the Universe, and can be used to distinguish between different scenarios for the physics that drives an accelerating expansion. This project will detect and monitor over 200 supernovae in order to test different hypotheses for the nature of the Dark Energy.
