JWST/NIRCam discovery of the first Y+Y brown dwarf binary: WISE J033605.05014350.4
Per Calissendorff, Matthew De Furio, Michael Meyer +25
We report the discovery of the first brown dwarf binary system with a Y dwarf primary, WISE J033605.05014350.4, observed with NIRCam on JWST with the F150W and F480M filters. We…
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…
Modelling Cosmic Radiation Events in the Tree-ring Radiocarbon Record
Qingyuan Zhang, Utkarsh Sharma, Jordan A. Dennis +6
Annually-resolved measurements of the radiocarbon content in tree-rings have revealed rare sharp rises in carbon-14 production. These 'Miyake events' are likely produced by rare in…
Solar Energetic Particle Ground-Level Enhancements and the Solar Cycle
Mathew Owens, Luke Barnard, Benjamin Pope +3
Severe geomagnetic storms appear to be ordered by the solar cycle in a number of ways. They occur more frequently close to solar maximum and declining phase, are more common in lar…
The TESS View of LOFAR Radio-Emitting Stars
Benjamin J. S. Pope, Joseph R. Callingham, Adina D. Feinstein +4
The recent detection of the M dwarf GJ 1151 at 144 MHz low radio frequencies using LOFAR has been interpreted as evidence of an exoplanet magnetically interacting with its host sta…
The population of M dwarfs observed at low radio frequencies
J. R. Callingham, H. K. Vedantham, T. W. Shimwell +12
Coherent low-frequency ( MHz) radio emission from stars encodes the conditions of the outer corona, mass-ejection events, and space weather. Previous low-frequency se…
