Radio Activity from the Rapidly Rotating T dwarf 2MASS 2228-4310
Kelvin Wandia, Michael A. Garrett, Aaron Golden +7
We present the detection of 2MASS J22282889-4310262 (2M2228), a T6/T6.5 brown dwarf, using the Karl G. Jansky Very Large Array (VLA) archival data observed at C band (4-8 GHz) over…
Upper Limits on Radio Emission from the K2-18 System
Kelvin Wandia, Chenoa Tremblay, Michael A. Garrett +11
Stellar and planetary magnetic fields play a crucial role in the habitability of a planet and the integrity of its atmosphere. The recently claimed detection of biosignatures, meth…
Radio Emission from a Nearby M dwarf Binary
Kelvin Wandia, Michael A. Garrett, Robert J. Beswick +7
We present the detection of the binary system 2MASS J02132062+3648506 AB using the Karl G. Jansky Very Large Array (VLA) archive data observed at 4-8 GHz. The system is a triple co…
Conducting High Frequency Radio SETI using ALMA
Louisa A Mason, Michael A Garrett, Kelvin Wandia +1
The Atacama Millimeter/Submillimeter Array (ALMA) remains unparalleled in sensitivity at radio frequencies above 35 GHz. In this paper, we explore ALMA's potential for narrowband t…
