A search for fast radio bursts associated with gamma-ray bursts using the YNAO 40-m radio telescope
We report on the search results of Fast Radio Bursts (FRBs) from three Gamma- ray Bursts (GRBs) at 2256 MHz using the 40-m radio telescope located at the YunNan Astronomical Observatory (YNAO). The search for signals was triggered by the Burst Alert Telescope (BAT) on- board the Swift satellite. Radio single pulses are searched in the data over a large range of dispersion measure from 0 to 5000 pc/cm3 in step of 50 pc/cm3. No FRB-like emission from the prompt phase of GRBs are detected with significance > 5?. If there are FRBs related to the GRBs, we set an upper limit on the ux density of radio pulses of 2.5 Jy for GRB140512A and 8.0 Jy for GRBs 140629A and 140703A with the sensitivity of the telescope. A statistical analysis of the GRB data reveals that the events detected above 5? are consistent with the thermal noise uctuations.
期刊介绍：
Serbian Astronomical Journal publishes original observations and researches in all branches of astronomy. The journal publishes:
Invited Reviews - review article on some up-to-date topic in astronomy, astrophysics and related fields (written upon invitation only),
Original Scientific Papers - article in which are presented previously unpublished author''s own scientific results,
Preliminary Reports - original scientific paper, but shorter in length and of preliminary nature,
Professional Papers - articles offering experience useful for the improvement of professional practice i.e. article describing methods and techniques, software, presenting observational data, etc.
In some cases the journal may publish other contributions, such as In Memoriam notes, Obituaries, Book Reviews, as well as Editorials, Addenda, Errata, Corrigenda, Retraction notes, etc.
