| 报告摘要/Abstract： | |
| The search for pulsars and different transients (rotating radio transients — RRAT, fast radio burst — FRB) will be discussed. The observations have based on a monitoring and regular survey on declinations −9 ◦< δ<+87◦ which carried out with the Large Phased Array of the Lebedev Physical Institute (LPA LPI). LPA is a transit telescope operating at 111 MHz with a bandwidth of 2.5 MHz. During the 8 years of the search, they have detected approximately 400 pulsars and transients, of which 81 are new pulsars and 79 are new RRATs. He also found a strong FRB. In the report, he will discuss the search methods, as well as the study of the sources found. | |
| 报告人介绍/Bio: | |
| Prof. Sergey A. Tyulbashev is currently the chief scientist of plasma astrophysics department of Lebedev Physics Institute and the director of Pushchino observatory. The title of his PhD thesis is "Investigation active galactic nuclei by interplanetary scintillation method at 102.5 MHz" (in 1997). The title of his doctor physics and mathematics thesis is "Properties of compact radio sources from observations in the meter wavelength range" (in 2014). He started the search for pulsars and transients (RRATs and FRB) in 2015. He is an expert in AGN observations by IPS method, Space Weather technology from IPS observations, pulsar and transient searching at low frequencies. | |
