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…
LOFAR observations of radio burst source sizes and scattering in the solar corona
Pearse C. Murphy, Eoin P. Carley, Aoife Maria Ryan +2
Low frequency radio wave scattering and refraction can have a dramatic effect on the observed size and position of radio sources in the solar corona. The scattering and refraction…
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…
Interferometric Imaging with LOFAR Remote Baselines of the Fine Structures of a Solar Type IIIb Radio Burst
PeiJin Zhang, Pietro Zucca, Sarrvesh Seethapuram Sridhar +8
Context. Solar radio bursts originate mainly from high energy electrons accelerated in solar eruptions like solar flares, jets, and coronal mass ejections. A subcategory of solar r…
A LOFAR Observation of Ionospheric Scintillation from Two Simultaneous Travelling Ionospheric Disturbances
Richard A. Fallows, Biagio Forte, Ivan Astin +55
This paper presents the results from one of the first observations of ionospheric scintillation taken using the Low-Frequency Array (LOFAR). The observation was of the strong natur…
Cassiopeia A, Cygnus A, Taurus A, and Virgo A at ultra-low radio frequencies
F. de Gasperin, J. Vink, J. P. McKean +49
The four persistent radio sources in the northern sky with the highest flux density at metre wavelengths are Cassiopeia A, Cygnus A, Taurus A, and Virgo A; collectively they are ca…
The frequency drift and fine structures of Solar S-bursts in the high frequency band of LOFAR
PeiJin Zhang, Pietro Zucca, ChuanBing Wang +8
Solar S-bursts are short duration ( s at decameter wavelengths) radio bursts that have been observed during periods of moderate solar activity, where S stands for short. The fr…
