"A LOFAR mini-survey for low-frequency radio emission from the nearest brown dwarfs." Monthly Notices of the Royal Astronomical Society 463:2202-2209. https://doi.org/10.1093/mnras/stw2065
We have conducted a mini-survey for low-frequency radio emission from some of the closest brown dwarfs to the Sun with rapid rotation rates: SIMP J013656.5 093347, WISEPC J150649.97 702736.0 and WISEPA J174124.26 255319.5. We have placed robust 3s upper limits on the flux density in the 111-169 MHz frequency range for these targets: WISE 1506: <0.72 mJy; WISE 1741: <0.87 mJy; SIMP 0136: <0.66 mJy. At 8 h of integration per target to achieve these limits, we find that systematic and detailed study of this class of object at LOFAR frequencies will require a substantial dedication of resources.
