Context : We report on new JVLA observations performed at 3 GHz and 5.5 GHz of Abell 2626 . The cluster has been the object of several studies in the recent years due to its peculiar radio emission , which shows a complex system of symmetric radio arcs characterized by a steep spectrum . The origin of these radio sources is still unclear . Due to their mirror symmetry toward the center , it has been proposed that they may be created by pairs of precessing jets powered by the inner AGN . Aims : The new JVLA observations were requested with the specific aim of detecting extended emission on frequencies higher than 1.4 GHz , in order to constrain the jet-precession model by analyzing the spectral index and radiative age patterns alongs the arcs . Methods : We performed a standard data reduction of the JVLA datasets with the software CASA . By combining the new 3 GHz data with the archival 1.4 GHz VLA dataset we produced a spectral index maps of the extended emission , and then we estimated the radiative age of the arcs by assuming that the plasma was accelerated in moving hot-spots tracing the arcs . Results : Thanks to the high sensitivity of the JVLA , we achieve the detection of the arcs at 3 GHz and extended emission at 5.5 GHz . We measure a mean spectral index < -2.5 for the arcs up to 3 GHz . No clear spectral index , or radiative age , trend is detected across the arcs which may challenge the interpretation based on precession or put strong constraints on the jet-precession period . In particular , by analyzing the radiative age distribution along the arcs , we were able to provide for the first time a time-scale < 26 Myr of the jet-precession period . Conclusions :
