Проведен поиск импульсного излучения на частоте 111 МГц в направлении 116 RRAT кандидатов. Для поиска использовались архивные данные, полученные на меридианном 128-лучевом радиотелескопе Большая Синфазная Антенна. Для каждого кандидата аккумулировано около шести суток наблюдений на интервале восьми лет. Обнаружено одиннадцать новых RRAT. Для шести из них удалось оценить периоды, а для четырех — построить средние профили. Часть кандидатов оказались известными пульсарами, наблюдаемыми в боковых лепестках радиотелескопа, и помехами. Для части кандидатов не удалось найти импульсов, имеющих отношение сигнала к шуму больше семи, и их природа остается не известной.
The magnetar (J1935+2154) is known as a source of soft gamma radiation.For the first time, radio emission from SGR1935+2154 in the form of a hyperflare was detected at a frequency of 1.25 GHz on the FAST radio telescope in May 2020.The magnetar enters the survey conducted on the Large Phased Array (LPA) radio telescope at a frequency of 111 MHz.A check of the previously published (Fedorova and Rodin, Bulletin of the Lebedev Physics Institute, 2021) pulse from the magnetar SGR1935+2154 was carried out.The data received on the LPA is recorded in parallel in two modes having low and high frequency-time resolution: 6 channels with a channel width of 415 kHz and a time resolution of Δt = 100 ms; 32 channels with a channel width of 78 kHz and a time resolution of Δt = 12.5 ms.The original search was carried out using data with low time-frequency resolution.The search for dispersed signals in the meter wavelength range is difficult, compared with the search in the decimeter range, due to scattering proportional to the fourth power of frequency and dispersion smearing of the pulse in frequency channels proportional to the second power of frequency.In order to collect a broadened pulse signal and obtain the best value of the signal-to-noise ratio (S/N), the search was carried out using an algorithm based on the convolution of multichannel data with a scattered pulse pattern.The shape of the template corresponds to the shape of a scattered pulse with a dispersion measure ( ) of 375 pc/cm 3 .For repeated verification, the same data was used in which the pulse from the magnetar was detected.An additional check of the published pulse was also carried out using data with a higher frequency-time resolution.Since the dispersion smearing in the frequency channel in the 32-channel data is 5 times less than in the 6-channel data, an increase approximately 2 times in the S/N pulse could be expected.Pulse radiation with S/N>4 having a pulse peak shift depending on from SGR1935+2154 was not detected in either 32-channel or 6-channel data.
