Mrk 1498 is part of a sample of galaxies with extended emission line regions ( extended outwards up to a distance of \sim 7 kpc ) suggested to be photo-ionized by an AGN that has faded away or that is still active but heavily absorbed .
Interestingly , the nucleus of Mrk 1498 is at the center of two giant radio lobes with a projected linear size of 1.1 Mpc .
Our multi-wavelength analysis reveals a complex nuclear structure , with a young radio source ( Giga-hertz Peaked Spectrum ) surrounded by a strong X-ray nuclear absorption , a mid-infrared spectrum that is dominated by the torus emission , plus a circum-nuclear extended emission in the [ OIII ] image ( with radius of \sim 1 kpc ) , most likely related to the ionization of the AGN , aligned with the small and large scale radio jet and extended also at X-rays .
In addition a large-scale extended emission ( up to \sim 10 kpc ) is only visible in [ OIII ] .
These data show conclusive evidence of a heavily absorbed nucleus and has recently restarted its nuclear activity .
To explain its complexity , we propose that Mrk 1498 is the result of a merging event or secular processes , such as a minor interaction , that has triggered the nuclear activity and produced tidal streams .
The large-scale extended emission that gives place to the actual morphology could either be explained by star formation or outflowing material from the AGN .
