Quasi-periodic eruptions are repeating burst of X-ray emission, that occur roughly periodically on time intervals of a few hours. Only 6 QPE source were so far detected. While the underlying mechanism for the observed X-ray emission is not fully understood, it is generally believed to be caused be the interaction between a star or stellar remnant with the accretion disk of a super massive black hole, potentially related to partial Tidal Disruption Events (pTDEs).

The some of the host galaxies of QPEs are detected in radio, and share that they are faint (few tenths of micro-Jansky). Here, we report on new HSA observations of the RXJ1301.9+2747 at 5GHz, which sheds light on the nature of the radio emission of the host galaxy.
