Abstract

The latest Fermi/LAT catalog newly included GRS 1734-292, which is a radio-quiet Seyfert galaxy. Both star formation and jet activity of this galaxy are insufficient to explain the observed gamma-ray flux. The remaining possibility is disk wind or corona. In this talk, we report the detection of the non- thermal mm-radio emission of GRS 1734-292 using the Atacama Large Millimeter/submillimeter Array (ALMA). This radio emission is likely a synchrotron counterpart of the gamma-ray emission. Based on the ALMA and Fermi measurements, we discuss the required physical conditions for corona and disk wind scenarios.
