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…
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…
CMEchaser, detecting line-of-sight occultations due to Coronal Mass Ejections
Golam Shaifullah, Caterina Tiburzi, Pietro Zucca
We present a python-based tool to detect the occultation of background sources by foreground Solar coronal mass ejections. The tool takes as input standard celestial coordinates of…
The MeerKAT Telescope as a Pulsar Facility: System verification and early science results from MeerTime
M. Bailes, A. Jameson, F. Abbate +72
We describe system verification tests and early science results from the pulsar processor (PTUSE) developed for the newly-commissioned 64-dish SARAO MeerKAT radio telescope in Sout…
Timing stability of black widow pulsars
Ann-Sofie Bak Nielsen, Gemma H. Janssen, Golam Shaifullah +13
We study the timing stability of three black widow pulsars, both in terms of their long-term spin evolution and their shorter-term orbital stability. The erratic timing behaviour a…
