Abstract
The LOFAR Two Meter Sky Survey (LOTSS) and the Faint Images of the Radio Sky at Twenty cm. Survey (FIRST) have both been creating catalogues of radio emitting galaxies across the Northern sky. We analyze detections and radio fluxes of binary interacting galaxies from the preliminary results of FIRST along with data from the newly released LOTSS catalogs. The sample of interacting galaxies was chosen from the K-band selected; Herschel observed set of gravitationally bound major merger candidates (H-KPAIRS) which include star forming members. These pairs have been the subject of studies with the Herschel Space Telescope. Our sample has IR derived dust masses and star formation rates (SFRs) based on the assumptions that IR emission is created by thermal sources. Newly measured spectral indexes (144-1400 MHz) including data from this early LOTSS reveal the contributions of thermal vs. non-thermal sources contributing to any far-infrared derived star formation rates (SFR) such as active nuclei. We also examine any morphological type dependence of our results such as statistical differences among the pairs categorized as spiral-spiral pairs of spiral elliptical pairs.
