摘要:

对宇宙的深度观测,通常作为巡天的一部分,是现代天文学的标志之一,因为它们可以允许大规模的合作,利用多个设施和共享知识。新一代的超大望远镜将发挥关键作用,因为它们具有角分辨率和收集微弱光源光线的能力。我们的模拟结合了技术,层析成像和观测信息,并受益于全球多共轭自适应光学(GMCAO)的方法,一个很好的证明方法,只利用自然的指导明星,以纠正科学的视野从大气湍流。通过模拟6000高红移星系在钱德拉深场南部地区的K波段观测,我们已经展示了如何ELT可以成功地进行测光调查,恢复形态和结构参数。我们在这里提出了一个广泛的统计数据的预期性能GMCAO配备ELT在22个知名的调查SR。

英文摘要:

Deep observations of the Universe, usually as a part of sky surveys, are one of the symbols of the modern astronomy because they can allow big collaborations, exploiting multiple facilities and shared knowledge. The new generation of extremely large telescopes will play a key role because of their angular resolution and their capability in collecting the light of faint sources. Our simulations combine technical, tomographic and observational information, and benefit of the Global-Multi Conjugate Adaptive Optics (GMCAO) approach, a well demonstrated method that exploits only natural guide stars to correct the scientific field of view from the atmospheric turbulence. By simulating K-band observations of 6000 high redshift galaxies in the Chandra Deep Field South area, we have shown how an ELT can carry out photometric surveys successfully, recovering morphological and structural parameters. We present here a wide statistics of the expected performance of a GMCAO-equipped ELT in 22 well-known surveys in terms of SR.
