摘要:

即将推出的大型光收集器阵列部署,以利用大气切伦科夫辐射的伽玛射线天文学在超过100 GeV,激发了越来越多的兴趣,在天文学中的应用强度干涉测量。事实上,计划中的多达100台望远镜的阵列将提供近5,000个基线,范围从不到50米到超过1000米。最近和持续的信号处理技术的发展加强了这种兴趣。重新审视恒星强度干涉成像是很好的科学动机。它将填补振幅干涉仪留下的短波长(B/V波段)和高角分辨率(< 0.1mas)的空白。这也将是利用量子光学进行天文观测的第一步,也是重要的一步,从而为未来的天文台铺平道路。在本文中,我们概述了科学的情况下,技术方法和时间表的强度干涉仪的建设和操作在可见光使用伽玛射线天文学空气切伦科夫望远镜作为接收器。

英文摘要:

The imminent availability of large arrays of large light collectors deployed to exploit atmospheric Cherenkov radiation for gamma-ray astronomy at more than 100GeV, motivates the growing interest in application of intensity interferometry in astronomy. Indeed, planned arrays numbering up to one hundred telescopes will offer close to 5,000 baselines, ranging from less than 50m to more than 1000m. Recent and continuing signal processing technology developments reinforce this interest. Revisiting Stellar Intensity Interferometry for imaging is well motivated scientifically. It will fill the short wavelength (B/V bands) and high angular resolution (< 0.1mas) gap left open by amplitude interferometers. It would also constitute a first and important step toward exploiting quantum optics for astronomical observations, thus leading the way for future observatories. In this paper we outline science cases, technical approaches and schedule for an intensity interferometer to be constructed and operated in the visible using gamma-ray astronomy Air Cherenkov Telescopes as receivers.
