| Description: | Using the European VLBI Network (EVN) and the Gran Telescopio Canarias (GTC), we have found the first fast radio burst source where the host galaxy is a low-mass satellite of a more massive central galaxy - similar to the Small Magellanic Cloud and Milky Way. This study expands the known diversity of FRB host environments and offers important insights for interpreting seemingly "hostless" or highly offset FRBs.
The results are presented in a paper entitled "A Hyperactive FRB Pinpointed in an SMC-Like Satellite Host Galaxy", which will soon be published in the Astrophysical Journal Letters. The figure above gives a wide-field red-green-blue (RGB) view of the FRB 20240114A field using DESI data. It shows the FRB host and EVN localisation ellipse as well as the central massive galaxy. |
