Tied-array beam flatfielding
Dirk Kuiper, Cees Bassa, Ziggy Pleunis +1
Context. Multi-element phased-array radio telescopes use digital beamforming to widen their field-of-view with numerous tied-array beams (TABs). These beams share bandpass variatio…
Pulsars identified in the LOFAR Two-metre Sky Survey at 144 MHz
G. A. C. Rijkers, C. G. Bassa, J. R. Callingham +1
We present the astrometric identification of 80 known radio pulsars as unresolved continuum sources detected at 144 MHz in the second data release of the LOFAR Two-metre Sky Survey…
Strongly polarised radio pulses from a new white-dwarf-hosting long-period transient
Sanne Bloot, Harish K. Vedantham, Cees G. Bassa +6
Long-period transients (LPTs) are a new and enigmatic class of objects that produce bright pulsations in the radio, with periods far exceeding those seen in rotationally powered pu…
The Crab Nebula at subarcsecond resolution with the International LOFAR Telescope
M. Arias, R. Timmerman, F. Sweijen +2
We present International LOw Frequency ARray (LOFAR) Telescope (ILT) observations of the Crab Nebula, the remnant of a core-collapse supernova explosion observed by astronomers in…
Broadband Polarized Radio Emission Detected from Starlink Satellites Below 100 MHz with NenuFAR
X. Zhang, P. Zarka, C. Viou +16
This study evaluates the impact of Starlink satellites on low-frequency radio astronomy below 100 MHz, focusing on challenges on data processing and scientific goals. We conducted…
Searches for signatures of ultra-light axion dark matter in polarimetry data of the European Pulsar Timing Array
N. K. Porayko, P. Usynina, J. Terol-Calvo +74
Ultra-light axion-like particles (ALPs) can be a viable solution to the dark matter problem. The scalar field associated with ALPs, coupled to the electromagnetic field, acts as an…
