Probing dark energy and modified gravity at DOME A

November 19, 2013 By Gong-Bo Zhao


Event Details

  • Date: August 21, 2010 10:00 am – 11:00 am
  • Categories: External talk - Academic

Speaker: Gong-Bo Zhao
Location: Xi’An China
Dark energy is an important science driver of many upcoming large-scale surveys. With small, stable seeing and low thermal infrared background, Dome A, Antarctica, offers a unique opportunity for shedding light on fundamental questions about the universe. We show that a deep, high-resolution imaging survey of 10,000 square degrees in emph{ugrizyJH} bands can provide competitive constraints on dark energy equation of state parameters using type Ia supernovae, baryon acoustic oscillations, and weak lensing techniques. Such a survey may be partially achieved with a coordinated effort of the Kunlun Dark Universe Survey Telescope (KDUST) in emph{yJH} bands over 5000–10,000 deg$^2$ and the Large Synoptic Survey Telescope in emph{ugrizy} bands over the same area. Moreover, the joint survey can take advantage of the high-resolution imaging at Dome A to further tighten the constraints on dark energy and to measure dark matter properties with strong lensing as well as galaxy–galaxy weak lensing.
