Parkes observations for project P1226 semester 2023OCTS_11

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）常被视为极具价值的宇宙学探针，然而要深入理解其传播所途经的前景环境——如银河系星际介质（Galactic ISM）与银晕（Milky Way Halo）——仍需开展大量研究工作。我们计划观测银河系的三个卫星矮椭球星系，以搜寻FRBs与脉冲星。我们拟借助新型CryoPAF的宽视场优势，对具有显著角大小的高恒星密度矮卫星星系进行巡天：包括Fornax、Sculptor及Sagittarius II。FRBs与脉冲星的探测成果，将使我们得以量化星系际介质（Circumgalactic Medium）对FRB色散的贡献，同时也能研究这些矮星系的暗物质晕。
