Observation And Data Analysis Of Fast Radio Bursts And Pulsars

The fast radio burst(FRB)was discovered by Lorimer et al.in 2007.It is a short time scale(ms),high energy(1039erg)astrophysical phenomenon near 1GHz.It's ex-tremely high brightness temperature and short time scale indicate very special astrophys-ical activities,It is of great significance for the development of radiation mechanism,the study of basic physics,and can be used as a cosmological probe.This thesis aims to illustrate how to discover new such signals from the perspective of FRB observation and data processing and some of the research of the author based on this.Chapter 1 introduces the research history and recent status of pulsars and fast ra-dio bursts.There are many connections between fast radio bursts and pulsars.The single-pulse phenomenon of pulsars has also been a research hotspot in the field of ra-dio transient sources in recent years.This chapter will briefly introduce the many exist-ing achievements of pulsars,and then focus on the single-pulse phenomenon of pulsars,as well as magnetars,a special kind of neutron star.The second part introduces the rapid development of fast radio bursts in last decade.Focusing on some observational phenomena that make us have a great leap in understanding fast radio bursts,such as repeating bursts,host galaxies,periodicity,etc.In April 2020 two telescope,CHIME and STARE2,simultaneously detected a fast radio burst from a magnetar in our galaxy.This chapter introduces the observation details and theoretical progress after this event.Chapter 2 introduces the basic concepts of radio telescopes and how to observe with the Parkes telescope remotely.There areseveral basic concepts need to be known before observation,such as beam,aperture efficiency,equivalent temperature,radio frequency interference,etc.The Pakres telescope was able to be observe remotely.Using a set of very friendly interactive system,the observation can be completed conveniently.Chapter 3 introduces the data processing pipelines.Firstly is the search method for periodic signals and single-pulses.This is the first step of pulsars and fast radio bursts research,and it is also one of the most important step.Then I discussed how to process the data observed by the Parkes telescope with UWL receiver.Due to the large bandwidth,the data needs to be cut first Finally,I show how to use Docker virtualization technology to achieve convenient environment building and deployment.Chapter 4 introduces the follow-up observations of two magnetars.With the dis-covery of FRB200428,magnetars has become the most likely physical origin of fast radio bursts.We conducted follow-up observation to SGR 1935+2154 after it entering an active phase on October 2020.Analyzing these data gives a limitation to it's single-pulse activity and periodic activity in the active period.In particular,the periodic flux limitation for SGR 1935+2154 is lower than the previously detected by the MNC tele-scope.Chapter 5 gives a brief outlook to my future work,based on what I'm doing now.It mainly includes the construction of a data analysis pipeline and observation of the single-pulse from pulsars and magnetars.
