Title: | Spectral Index of the Filaments in the Abell 523 Radio Halo | Authors: | VACCA, VALENTINA GOVONI, FEDERICA Perley, Richard A. MURGIA, MATTEO CARRETTI, ETTORE LOI, FRANCESCA FERETTI, LUIGINA Giovannini, Gabriele |
Issue Date: | 2021 | Journal: | GALAXIES | Number: | 9 | Issue: | 4 | First Page: | 112 | Abstract: | The galaxy cluster Abell 523 hosts a radio halo characterized by the presence of two filaments transversely located with respect to the cluster merger axis. In this paper, we present a spectral index image of these filaments between 1.410 and 1.782 GHz obtained with Jansky Very Large Array observations. We find a steepening of the spectral index of the filaments at frequencies 1.4 GHz and an indication that bright patches are characterized by flat spectral indices. Our results are consistent with a scenario of highly-efficient turbulence induced by merger phenomena. | URI: | http://hdl.handle.net/20.500.12386/32299 | URL: | https://www.mdpi.com/2075-4434/9/4/112 https://api.elsevier.com/content/abstract/scopus_id/85120777008 |
