Based on the first CHIME/FRB catalogue, three volume-limited samples of fast radio bursts (FRBs) are built, with 1, 2, and 3 corresponding to a fluence cut 5, 3, respectively. The Lynden-Bell's c^- method was applied study their energy function event rate evolution redshift (z). Using non-parametric Kendall's τ statistics, it is found that FRB (E) strongly evolves as E(z) for sample 3. After removing dependence, local distributions can be well described by broken power-law form erg....
The algorithm of the ensemble pulsar time based on optimal Wiener filtration method has been constructed. This allows separation contributions to post-fit timing residuals atomic clock and itself. Filters were designed with use cross- autocovariance functions residuals. applied data millisecond pulsars PSR B1855+09 B1937+21 allowed filtering out scale component from data. Direct comparison terrestrial TT(BIPM06) PT$_{\rm ens}$ revealed that fractional instability TT(BIPM06)--PT$_{\rm is...
Using a large sample of fast radio bursts (FRBs) from the first CHIME/FRB catalog, we apply Lynden-Bell's c$^-$ method to study their energy function and formation rate evolutions with redshift. It is found non-parametric Kendell's $\tau$ statistics that FRB strongly evolves cosmological redshift as $E(z)\propto(1 + z)^{5.23}$. After removing dependence, local distribution can be described by broken power-law form $\Psi(E_{0})\propto E_{0}^{-0.38}$ for low-energy segment E_{0}^{-2.01}$...
An algorithm of the ensemble pulsar time based on Wiener filtration method has been constructed. This allowed separation contributions an atomic clock and a itself to post-fit timing residuals. The applied data millisecond pulsars PSR B1855+09 B1937+21 filter out scale component from phase variations. Direct comparison terrestrial TT(BIPM96) PTens displayed that difference – is within ±0.4 μs range. A new limit gravitational wave background was established be Ωgh2∼10−10.
Regular high-precision timing of the binary pulsars J0613−0200, J1012+5307, J1022+1001, J1640+2224, J1643−1224, J1713+0747, J2145−0750 and pulsar B1937+21 has been conducted at Kalyazin (Russia) radio telescope RT-64 0.6 GHz over more than 6 years. Several monitored have found to be good probes for gravitational wave background (GWB) tests, while others, having a shorter orbital period, can used establishing dynamical timescale. Upper limits GWB energy density were estimated.

On the Pushchino Radio Astronomy Observatory of Lebedev Physical Institute by radio telescope BSA (Big Scanning Antenna) in 2012 started daily multi-beam observations at frequency range 109- 112 MHz. The number bands from 6 to 32, while time constants 0.1 0.0125 sec. This data is an enormous opportunity for both short and long-term monitoring various classes sources (including transients), Earth's ionosphere, interplanetary interstellar plasma monitoring, search different sources, etc. A...
We conducted VLBI experiments on the pulsar PSR 0329+54 with Kashima (Japan)-Kalyazin (Russia) baseline in 1995 March and 1996 May. An absolute astrometric measurement was applied by using analysis software SOLVE CALC, which were developed NASA/GSFC for geodesy astrometry.
