| description |
Purpose: Due to the significant increase of a number of pulsars discovered with high-frequency radio telescopes over the last ten years and the necessity to obtain accurate parameters of their decameter radiation (as well as to identify single pulses detected with the UTR-2), the second decameter census of these sources with the UTR-2 radio telescope became needed.Design/methodology/approach: Single pulses detected as a result of the first decameter survey of pulsars and transient emission sources can be anomalously intense pulses of the recently discovered pulsars. Identification is only possible with an accurate information on the dispersion measure (DM) of each of these sources. Given that the new pulsars are likely to have a low radiant flux density, in contrast to the first decameter pulsar census [1], the second one plans to increase the signal-to-noiseratio by increasing the observation time of each pulsar. This paper gives a complete list of the studied sources, limited by the dispersion measure (DM< 30 pc·cm-³), period (P> 0.1 s) and declination (δ>-10º), known for the beginning of 2020, as well as some examples of the decameter pulsar radio emission detected by means of pipeline data processing with the possibility of flexible adjustment of search parameters.Findings: For the first time in the low-frequency wavelength range, the radio emission from the PSR J2325-0530, PSR J0613+3731, and PSR J1426+52 pulsars has been detected. The main result of present work is specified period for the latter pulsar (PSR J1426+52), being 0.995866 s ± 5 µs, the other parameters of its radio emission are also specified.Conclusions: High sensitivity of the UTR-2 radio telescope, its receiving equipment and efficient data processing and analysis pipeline allow detecting the decameter radiation of weak pulsars, as well as obtaining their parameters with the accuracy sufficient for identification of previously discovered transient signals.Key words: pulsar, census, decameter wavelengths, pulsar period, flux, dispersion measure, UTR-2Manuscript submitted 27.07.2020Radio phys. radio astron. 2020, 25(3): 193-210REFERENCES1.

Identification is only possible with an accurate information on the dispersion measure (DM) of each of these sources. Given that the new pulsars are likely to have a low radiant flux density, in contrast to the first decameter pulsar census [1], the second one plans to increase the signal-to-noiseratio by increasing the observation time of each pulsar. This paper gives a complete list of the studied sources, limited by the dispersion measure (DM< 30 pc·cm-³), period (P> 0.1 s) and declination (δ>-10º), known for the beginning of 2020, as well as some examples of the decameter pulsar radio emission detected by means of pipeline data processing with the possibility of flexible adjustment of search parameters.Findings: For the first time in the low-frequency wavelength range, the radio emission from the PSR J2325-0530, PSR J0613+3731, and PSR J1426+52 pulsars has been detected. The main result of present work is specified period for the latter pulsar (PSR J1426+52), being 0.995866 s ± 5 µs, the other parameters of its radio emission are also specified.Conclusions: High sensitivity of the UTR-2 radio telescope, its receiving equipment and efficient data processing and analysis pipeline allow detecting the decameter radiation of weak pulsars, as well as obtaining their parameters with the accuracy sufficient for identification of previously discovered transient signals.Key words: pulsar, census, decameter wavelengths, pulsar period, flux, dispersion measure, UTR-2Manuscript submitted 27.07.2020Radio phys. radio astron. 2020, 25(3): 193-210REFERENCES1.

In: Scientific Workshop – Astrophysics with E-LOFAR [online]. [viewed 14 August 2020]. Available from: https://www.researchgate.net/publication/312367692_Largescale_structure_of_the_Northern_sky_at_decametric_waves DOI: 10.13140/RG.2.2.28090.82881 Purpose: Due to the significant increase of a number of pulsars discovered with high-frequency radio telescopes over the last ten years and the necessity to obtain accurate parameters of their decameter radiation (as well as to identify single pulses detected with the UTR-2), the second decameter census of these sources with the UTR-2 radio telescope became needed.Design/methodology/approach: Single pulses detected as a result of the first decameter survey of pulsars and transient emission sources can be anomalously intense pulses of the recently discovered pulsars. Identification is only possible with an accurate information on the dispersion measure (DM) of each of these sources. Given that the new pulsars are likely to have a low radiant flux density, in contrast to the first decameter pulsar census [1], the second one plans to increase the signal-to-noiseratio by increasing the observation time of each pulsar. This paper gives a complete list of the studied sources, limited by the dispersion measure (DM< 30 pc·cm-³), period (P> 0.1 s) and declination (δ>-10º), known for the beginning of 2020, as well as some examples of the decameter pulsar radio emission detected by means of pipeline data processing with the possibility of flexible adjustment of search parameters.Findings: For the first time in the low-frequency wavelength range, the radio emission from the PSR J2325-0530, PSR J0613+3731, and PSR J1426+52 pulsars has been detected. The main result of present work is specified period for the latter pulsar (PSR J1426+52), being 0.995866 s ± 5 µs, the other parameters of its radio emission are also specified.Conclusions: High sensitivity of the UTR-2 radio telescope, its receiving equipment and efficient data processing and analysis pipeline allow detecting the decameter radiation of weak pulsars, as well as obtaining their parameters with the accuracy sufficient for identification of previously discovered transient signals.Key words: pulsar, census, decameter wavelengths, pulsar period, flux, dispersion measure, UTR-2Manuscript submitted 27.07.2020Radio phys. radio astron. 2020, 25(3): 193-210REFERENCES1.

Ототожнення є можливим лише за наявності точної інформації про міру дисперсії (МД), характерну для цих пульсарів. Враховуючи те, що нові пульсари, ймовірно, мають невисоке значення густини потоку випромінювання, у другому переписі, на відміну від першого декаметрового перепису пульсарів, планується збільшити співвідношення сигнал/шум за рахунок збільшення часу спостереження кожного пульсара. В роботі надається повний перелік досліджуваних джерел, обмежених за мірою дисперсії (DM< 30 pc·cm-³), педіодом пульсара (P> 0.1 s) та схиленням (δ>-10º), відомих на початок 2020 р., а також приклади детектування декаметрового випромінювання пульсарів за допомогою конвеєрної обробки даних спостережень з можливістю гнучкого налаштування параметрів пошуку.Результати:Вперше в низькочастотному діапазоні було виявлено радіовипромінювання пульсарів PSR J2325-0530, PSR J0613+3731 та PSR J1426+52. Основним результатом цієї роботи є уточнення періоду останнього з них (PSR J1426+52), що складає 0.995866 с ± 5 мкс. Було уточнено також інші параметри його радіовипромінювання.Висновок: Висока чутливість радіотелескопа УТР-2, його приймальної апаратури й ефективний конвеєр обробки й аналізу даних дозволяють виявляти декаметрове випромінювання слабких пульсарів, а також отримувати його параметри з точністю, достатньою для ототожнення відкритих раніше транзієнтних сигналів.Ключові слова: пульсар, перепис, декаметровий діапазон, період пульсара, потік, міра дисперсії, УТР-2Стаття надійшла до редакції 27.07.2020Radio phys. radio astron. 2020, 25(3): 193-210СПИСОК ЛІТЕРАТУРИ1.
