RAD@home discovery of a bow-and-arrow radio galaxy tracing a ~560 kpc bow-shock structure in a multi-halo environment
Ananda Hota, Pratik Dabhade, Shubhrangshu Ghosh +9
We report the RAD@home citizen science discovery of a unique bow-and-arrow-shaped radio galaxy (BAARG; RAD J104501.6+352852, z = 0.159) identified in LoTSS DR2. The source exhibits…
The LOFAR Two-metre Sky Survey: VII. Third Data Release
T. W. Shimwell, M. J. Hardcastle, C. Tasse +99
We present the third data release of the LOFAR Two-metre Sky Survey (LoTSS-DR3). The survey images cover 88% of the northern sky and were created from 12,950 hrs of data (18.6 PB)…
The LOFAR Two-Metre Sky Survey (LoTSS): VI. Optical identifications for the second data release
M. J. Hardcastle, M. A. Horton, W. L. Williams +49
The second data release of the LOFAR Two-Metre Sky Survey (LoTSS) covers 27% of the northern sky, with a total area of deg. The high angular resolution of LOFAR wi…
V-LoTSS: The Circularly-Polarised LOFAR Two-metre Sky Survey
J. R. Callingham, T. W. Shimwell, H. K. Vedantham +44
We present the detection of 68 sources from the most sensitive radio survey in circular polarisation conducted to date. We use the second data release of the 144 MHz LOFAR Two-metr…
Discovery of recurrent flares of 6.7 GHz methanol maser emission in Cepheus A HW2
M. Durjasz, M. Szymczak, M. Olech +1
Context: Class II methanol masers at 6.7 GHz originate close to high-mass young stellar objects (HMYSOs). Their high sensitivity to local condition variations makes them a useful m…
Detection of periodic flares in 6.7 GHz methanol masers G45.804-0.356 and G49.043-1.079
Mateusz Olech, Michał Durjasz, Marian Szymczak +1
Context: Periodicity in 6.7 GHz methanol maser sources is a rare phenomenon that was discovered during long-term monitoring programmes. Understanding the underlying processes that…
The LOFAR Two-metre Sky Survey -- V. Second data release
T. W. Shimwell, M. J. Hardcastle, C. Tasse +103
In this data release from the LOFAR Two-metre Sky Survey (LoTSS) we present 120-168MHz images covering 27% of the northern sky. Our coverage is split into two regions centred at ap…
Molecular line search toward the flaring 6.7-GHz methanol masers of G24.33+0.13 and G359.6-0.243: rare maser transitions detected
Tiege McCarthy, Gabor Orosz, Simon Ellingsen +8
We have performed a molecular line search toward the flaring 6.7-GHz masers G24.33+0.13 and G359.62-0.24 using the Australia Telescope Compact Array. We present spectra of the 6.7-…
Sub-arcsecond imaging with the International LOFAR Telescope: II. Completion of the LOFAR Long-Baseline Calibrator Survey
Neal Jackson, Shruti Badole, John Morgan +69
The Low-Frequency Array (LOFAR) Long-Baseline Calibrator Survey (LBCS) was conducted between 2014 and 2019 in order to obtain a set of suitable calibrators for the LOFAR array. In…
Radio observations of planetary nebulae: no evidence for strong radial density gradients
Marcin Hajduk, Peter A. M. van Hoof, Karolina Śniadkowska +4
Radio continuum observations trace thermal emission of ionized plasma in planetary nebulae and bring useful information on nebular geometries. A model of homogeneous sphere or shel…
