资源简介:
Fast Radio Bursts(FRBs) are often proposed as useful cosmological probes, however much work is needed to better understand the foreground environment that it propgates through, such as the Galactic ISM and Milky Way Halo. We propose to observe three satellite dwarf spheroidal galaxies of the Milky Way to search for FRBs and pulsars. We plan to take advantage of the new CryoPAF's wide field of view to survey high stellar density dwarf satellite galaxies with substantial angular sizes: Fornax, Sculptor and Sagittarius II. Detections of FRBs and pulsars will allow us to measure the Circumgalactic Medium contribution to FRB dispersion and also the dark matter halos of these dwarf galaxies.
快速射电暴(Fast Radio Bursts, FRBs)常被视作极具应用前景的宇宙学探针,但当前仍需开展大量研究以深入厘清其传播途径的前景环境,例如银河系星际介质(Interstellar Medium, ISM)与银河系晕。我们计划对银河系的三颗卫星矮椭球星系开展观测,以搜寻快速射电暴与脉冲星。本次观测将借助新型CryoPAF的大视场能力,对具有显著角尺度、高恒星密度的矮卫星星系展开巡天,目标涵盖天炉座(Fornax)、玉夫座(Sculptor)以及人马座II(Sagittarius II)。若成功探测到快速射电暴与脉冲星,我们将能够量化环绕星系介质对快速射电暴色散的贡献,同时测定这些矮星系的暗物质晕。
