Estudio de fuentes difusas sobre el radiohalo de TXS 0828+193

Abstract

In this paper we analyzed images from the Hubble Space Telescope of TXS 0828+193, a radiogalaxy at high redshift (=2.572), with the objective of studying a faint pair of sources recently discovered in order to confirm photometrically its physical relationship with this radiogalaxy. Using combined SExtractor and GAIA values of 26 and 27.5 were obtained, respectively for both regions. Although very weak values were obtained to be able to obtain the corresponding redshift photometric, we present some proposals that allow to determine the nature of these two diffuse regions.
