Pulsar timing and polarimetry: results and perspectives
Konstantin A. Postnov, Nataliya K. Porayko, Maxim S. Pshirkov
Pulsar timing, i.e. the analysis of the arrival times of pulses from a pulsar, is a powerful tool in modern astrophysics. It allows us to measure the time delays of an electromagne…
Testing the accuracy of the ionospheric Faraday rotation corrections through LOFAR observations of bright northern pulsars
N. K. Porayko, A. Noutsos, C. Tiburzi +13
Faraday rotation of polarized emission from pulsars measured at radio frequencies provides a powerful tool to investigate the interstellar and interplanetary magnetic fields. Howev…
RadioAstron gravitational redshift experiment: status update
D. A. Litvinov, U. Bach, N. Bartel +25
A test of a cornerstone of general relativity, the gravitational redshift effect, is currently being conducted with the RadioAstron spacecraft, which is on a highly eccentric orbit…
Measurement of the gravitational redshift effect with RadioAstron satellite
A. V. Birukov, V. L. Kauts, D. A. Litvinov +2
RadioAstron satellite admits in principle a testing the gravitational redshift effect with an accuracy of better than . It would surpass the result of Gravity Probe A miss…
Pulsar timing constraints on narrow-band stochastic signals
Konstantin A. Postnov, Nataliya K. Porayko
We consider the sensitivity of the pulsar timing array (PTA) technique to specific kind of narrow-band stochastic signals in nano-Hz frequency range. Specifically, we examine the n…
