We report on new JVLA observations performed at 3 GHz and 5.5 GHz of Abell2626. The cluster has been the object of several studies in the recent yearsdue to its peculiar radio emission, which shows a complex system of symmetricradio arcs characterized by a steep spectrum. The origin of these radio sourcesis still unclear. Due to their mirror symmetry toward the center, it has beenproposed that they may be created by pairs of precessing jets powered by theinner AGN. The new JVLA observations were requested with the specific aim ofdetecting extended emission on frequencies higher than 1.4 GHz, in order toconstrain the jet-precession model by analyzing the spectral index andradiative age patterns alongs the arcs. We performed a standard data reductionof the JVLA datasets with the software CASA. By combining the new 3 GHz datawith the archival 1.4 GHz VLA dataset we produced a spectral index maps of theextended emission, and then we estimated the radiative age of the arcs byassuming that the plasma was accelerated in moving hot-spots tracing the arcs.Thanks to the high sensitivity of the JVLA, we achieve the detection of thearcs at 3 GHz and extended emission at 5.5 GHz. We measure a mean spectralindex <-2.5 for the arcs up to 3 GHz. No clear spectral index, or radiativeage, trend is detected across the arcs which may challenge the interpretationbased on precession or put strong constraints on the jet-precession period. Inparticular, by analyzing the radiative age distribution along the arcs, we wereable to provide for the first time a time-scale < 26 Myr of the jet-precessionperiod.
