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…

Dispersion measure variability for 36 millisecond pulsars at 150MHz with LOFAR

J. Y. Donner, J. P. W. Verbiest, C. Tiburzi +19

Radio pulses from pulsars are affected by plasma dispersion, which results in a frequency-dependent propagation delay. Variations in the magnitude of this effect lead to an additio…

Low-frequency pulse profile variation in PSR B2217+47: evidence for echoes from the interstellar medium

D. Michilli, J. W. T. Hessels, J. Y. Donner +17

We have observed a complex and continuous change in the integrated pulse profile of PSR B2217+47, manifested as additional components trailing the main peak. These transient compon…

A LOFAR census of non-recycled pulsars: average profiles, dispersion measures, flux densities, and spectra

A. Bilous, V. Kondratiev, M. Kramer +24

We present first results from a LOFAR census of non-recycled pulsars. The census includes almost all such pulsars known (194 sources) at declinations and Galac…

Wide-Band, Low-Frequency Pulse Profiles of 100 Radio Pulsars with LOFAR

M. Pilia, J. W. T. Hessels, B. W. Stappers +84

LOFAR offers the unique capability of observing pulsars across the 10-240 MHz frequency range with a fractional bandwidth of roughly 50%. This spectral range is well-suited for stu…

A LOFAR census of millisecond pulsars

V. I. Kondratiev, J. P. W. Verbiest, J. W. T. Hessels +29

We report the detection of 48 millisecond pulsars (MSPs) out of 75 observed thus far using the LOFAR in the frequency range 110-188 MHz. We have also detected three MSPs out of nin…
