论文摘要
长伽玛射线突发（LGRB）可用于解决有关现代宇宙形成的关键问题，包括：恒星形成率如何在高红移时发展？何时何时，如何重新定时化了层次培养基？什么过程控制着早期的化学富集？当巨大的恒星崩溃以形成黑洞并这样做时，LGRB信号是恒星形成速率的独立示踪剂。 LGRB余辉是一种明亮的背光，可在吸收中查看宿主星系和播层间培养基。 Gamow Explorer将被优化以搜索高红移LGRB，Z> 6的检测率至少是Neil Gehrels Swift天文台的十倍。此外，通过使用Photo-Z技术来自主识别Z> 6> 6的红移LGRB的80％，可以通过大型地面望远镜和JWST进行快速跟进，以进行光谱和宿主星系识别，从而超越了Swift。 Gamow Explorer将于2028年向2021年的NASA Midex机会提议。
Long Gamma Ray Bursts (LGRBs) can be used to address key questions on the formation of the modern universe including: How does the star formation rate evolve at high redshift? When and how did the intergalactic medium become re-ionized? What processes governed its early chemical enrichment? A LGRB signals when a massive star collapses to form a black hole and in doing so provides an independent tracer of the star formation rate. The LGRB afterglow is a bright back-light to view the host galaxy and intergalactic medium in absorption. The Gamow Explorer will be optimized to search for high redshift LGRBs, with a z>6 detection rate at least ten times the Neil Gehrels Swift Observatory. Furthermore it will go beyond Swift by using the photo-z technique to autonomously identify >80% of z>6 redshift LGRBs to enable rapid follow up by large ground based telescopes and JWST for spectroscopy and host galaxy identification. The Gamow Explorer will be proposed to the 2021 NASA MIDEX opportunity for launch in 2028.
