We report the multiwavelength observations of one intermediate redshift ( z =0.3884 ) galaxy in the Marano Field .
These data include ISOCAM middle infrared , VLT/FORS2 spectroscopic and photometric data , associated with the ATCA 1.4 GHz radio and ROSAT PSPC X-ray observations from literature .
The Spectral Energy Distribution obtained by VLT spectroscopy exhibits its early-type galaxy property , while , in the same time , it has obvious [ O III ] 5007 emission line .
The diagnostic diagram from the optical emission line ratios shows its Seyfert galaxy property .
Its infrared-radio relation follows the correlation of sources detected at 15 \mu m and radio .
It has a high X-ray luminosity of 1.26 \times 10 ^ { 43 } ergs s ^ { -1 } , which is much higher than the general ellipticals with the similar B band luminosity , and is about 2 orders of magnitude higher than the derived value from the star forming tracer , the FIR luminosity .
This means that the X-ray sources of this galaxy are not stellar components , but the AGN is the dominant component .
