On Stellar Migration from Andromeda to the Milky Way
Lukas Gülzow, Malcolm Fairbairn, Dominik J. Schwarz
Recent Gaia observations suggest that some hypervelocity stars (HVSs) might originate from outside the Galaxy. We ask if these HVSs could come from as far as Andromeda. Therefore,…
The cosmic radio dipole: Bayesian estimators on new and old radio surveys
J. D. Wagenveld, H-R. Klöckner, D. J. Schwarz
The cosmic radio dipole is an anisotropy in the number counts of radio sources, analogous to the dipole seen in the cosmic microwave background (CMB). Measurements of source counts…
Matching LOFAR sources across radio bands
Lukas Böhme, Dominik J. Schwarz, Francesco de Gasperin +2
Aims. With the recent preliminary release of the LOFAR LBA Sky Survey (LoLSS), the first wide-area, ultra-low frequency observations from LOFAR were published. Our aim is to combin…
Weakly interacting massive particle cross section limits from LOFAR observations of dwarf spheroidal galaxies
L. Gajović, F. Welzmüller, V. Heesen +8
Weakly interacting massive particles (WIMPs) can self-annihilate, thus providing us with a way to indirectly detect dark matter (DM). Dwarf spheroidal (dSph) galaxies are excellent…
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…
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…
