Today's colloquium: Conducting the deepest all-sky radio pulsar survey: The High Time Resolution Universe survey
| Submitter: | Cherry Ng (MPIfR) |
| Description: | The extreme conditions found in and around pulsars make them fantastic natural laboratories, providing insights into a rich variety of aspects of fundamental physics and astronomy. To discover more pulsars we have begun the High Time Resolution Universe (HTRU) survey: a blind survey of the northern sky with the 100-m Effelsberg radio telescope in Germany, and a twin survey of the southern sky with the 64-m Parkes radio telescope in Australia. The HTRU survey uses multi-beam receivers and backends constructed using recent advancements in technology, providing unprecedentedly high time and frequency resolution to probe deeper into the Galaxy than ever before. Observations from Parkes have recently been completed, and it is thus a suitable moment to review the success of the survey. In my talk I will discuss the discovery highlights such as the magnetar, two 'planet-pulsar' binaries and the Fast Radio Bursts (FRBs) from cosmological distances. The HTRU low-latitude data promises to provide the deepest large-scale search ever of the Galactic plane region. I have already discovered 60 new pulsars from processing 50% of the Galactic plane data. I will present an innovative segmented search technique, which aims to increase our chances of discoveries of highly accelerated relativistic binary systems, including the potential pulsar-black-hole binaries. I will provide an overview of the northern survey with Effelsberg and present an update on the survey status. |
