Parkes observations for project P1226 semester 2023OCTS_22

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）常被视为重要的宇宙学探针，然而要更好地理解其传播所经过的前景环境（如银河系星际介质（ISM）和银晕），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FRBs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卫星矮星系进行巡天观测：包括天炉座（Fornax）、玉夫座（Sculptor）和人马座II（Sagittarius II）星系。FRBs和脉冲星的探测将使我们能够测量环星系介质（Circumgalactic Medium）对FRB色散的贡献，以及这些矮星系的暗物质晕。
