Parkes observations for project P1226 semester 2023OCTS_19

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（FRBs）常被视为有效的宇宙学探针，然而，要深入理解其传播所经的前景环境（例如银河系星际介质（ISM）和银河系晕（Milky Way Halo）），仍需开展大量研究。我们计划观测银河系的三个卫星矮椭球星系，以搜寻快速射电暴和脉冲星。我们拟利用新型CryoPAF的宽视场优势，对具有较大角大小的高恒星密度矮卫星星系进行巡天观测，包括天炉座（Fornax）、玉夫座（Sculptor）和人马座II（Sagittarius II）星系。快速射电暴和脉冲星的探测结果，将使我们能够测量环星系介质对快速射电暴色散的贡献，以及这些矮星系的暗物质晕。
