摘要

再电离时代(EoR)预示着我们今天所认识的宇宙的到来，包括恒星、星系和超大质量黑洞。许多检测星系际介质(IGM)原子成分红移氢特征的实验正在进行中(例如PAPER, MWA, LOFAR)。由于信号微弱，前景明亮，以及仪器系统的挑战，多种技术对于创建更可靠的探测和提供早期星系演化的完整图景至关重要。

DACOTA: The dense array for cosmological transitions

The Epoch of Reionization (EoR) heralded the advent of the Universe we recognize today, containing stars, galaxies and super-massive black holes. A number of experiments to detect the red-shifted hydrogen signature of the atomic component of the intergalactic medium (IGM) are on-going (e.g. PAPER, MWA, LOFAR). Due to the faintness of the signal, the bright foregrounds, and the challenge of instrumental systematics, multiple techniques are essential to create a more robust detection and to provide the complete picture on the evolution of early galaxies.
