The impact of Solar wind variability on pulsar timing
C. Tiburzi, G. M. Shaifullah, C. G. Bassa +22
High-precision pulsar timing requires accurate corrections for dispersive delays of radio waves, parametrized by the dispersion measure (DM), particularly if these delays are varia…
Scintillation of PSR B1508+55 -- the view from a 10,000-km baseline
V. R. Marthi, D. Simard, R. A. Main +6
We report on the simultaneous Giant Metrewave Radio Telescope (GMRT) and Algonquin Radio Observatory (ARO) observations at 550-750 MHz of the scintillation of PSR B1508+55, resulti…
Pulsars with NenuFAR: backend and pipelines
L. Bondonneau, J. -M. Grießmeier, G. Theureau +27
NenuFAR (New extension in Nançay upgrading LoFAR) is a new radio telescope developed and built on the site of the Nançay Radio Observatory. It is designed to observe the largely un…
Measuring Interstellar Delays of PSR J0613-0200 over 7 years, using the Large European Array for Pulsars
R. A. Main, S. A. Sanidas, J. Antoniadis +19
Using data from the Large European Array for Pulsars (LEAP), and the Effelsberg telescope, we study the scintillation parameters of the millisecond pulsar J0613-0200 over a 7 year…
Detection of 15 bursts from FRB 180916.J0158+65 with the uGMRT
Visweshwar Ram Marthi, Tasha Gautam, Dongzi Li +5
We report the findings of a uGMRT observing campaign on FRB 180916.J0158+65, discovered recently to show a 16.35-day periodicity of its active cycle. We observed the source at 550-…
The - Diagram: Transforming pulsar scintillation spectra to coordinates on highly anisotropic interstellar scattering screens
Tim Sprenger, Olaf Wucknitz, Robert Main +2
We introduce a novel analysis technique for pulsar secondary spectra. The power spectrum of pulsar scintillation (referred to as the "secondary spectrum") shows differential delays…
