The PARADIGM Project II: Characterising Nuclear and Diffuse Radio Components in Local U/LIRGs

Geferson Lucatelli, Rob Beswick, Javier Moldón +14

Disentangling SF and AGN emission is essential for understanding galaxy evolution, yet remains challenging in merging systems where both processes are enhanced and spatially intert…

A Narrowband Technosignature Search Toward the Hycean Candidate K2-18b Using the VLA and MeerKAT

C. D. Tremblay, S. Chaudhary, Megan G. Li +12

K2-18b, a sub-Neptune exoplanet located in the habitable zone of its host star, has emerged as an important target for atmospheric characterization and assessments of potential hab…

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…
