Discovery of 24 radio-bright quasars at $4.9 \leq z \leq6.6$ using low-frequency radio observations
Gloudemans, A. J.; Duncan, K. J.; Saxena, A.; Harikane, Y.; Hill, G. J.; Zeimann, G. R.; Rottgering, H. J. A.; Yang, D.; Best, P. N.; Banados, E.; Drabent, A.; Hardcastle, M. J.; Hennawi, J. F.; Lansbury, G.; Magliocchetti, M.; Miley, G. K.; Nanni, R.; Shimwell, T. W.; Smith, D. J. B.; Venemans, B.P.; Wagenveld, J. D. (2022-12-31)High redshift quasars ($z>5$) that also shine brightly at radio wavelengths are unique signposts of supermassive black hole activity in the early universe. However, bright radio sources at $z\ge5$ are extremely rare and ... -
Plausible association of distant late M dwarfs with low-frequency radio emission
Gloudemans, A. J.; Callingham, J. R.; Duncan, K. J.; Saxena, A.; Harikane, Y.; Hill, G. J.; Zeimann, G. R.; Rottgering, H. J. A.; Hardcastle, M. J.; Pineda, J. S.; Shimwell, T. W.; Smith, D. J. B.; Wagenveld, J. D. (2023-10-17)We present the serendipitous discovery of eight distant (> 50 pc) late M dwarfs with plausible associated radio emission at 144 MHz. The M-dwarf nature of our sources has been confirmed with optical spectroscopy performed ...
