摘要III Zw 2 is the prototype of radio-intermediate quasars. Although there is the evidence of possessing strong jet, significant gamma-ray emission has not been reported before. In this work, we carry out a detailed analysis of the latest Fermi-LAT Pass. 8 data. No significant gamma-ray signal has been detected in the time-averaged 7-year Fermi-LAT data of III Zw 2; however, we have identified two distinct gamma-ray flares with isotropic luminosities of similar to 10(45) erg s(-1). Multiwavelength data analysis (also including the optical photometric observations from Yunnan Observatories) are presented and the main finding is simultaneous optical and gamma-ray flares of III Zw 2 appearing in 2009 November. Violent gamma-ray variability with a doubling timescale of 2.5 hr was detected in another gamma-ray flare in May 2010, for which the 3-hr gamma-ray peak flux is similar to 250 times of the average flux in 7 years. Rather similar behaviors are observed in blazars and the blazar model can reasonably reproduce the spectral energy distribution of III Zw 2 in a wide energy range, strongly suggesting that its central engine resembles that of blazars. In view of its core, which shares radio similarities with young radio sources, together with weak extended radio lobe emission, we suggest that III Zw 2 harbors a recurrent activity core and thus serves as a valuable target for investigating the fueling and triggering of the activity in radio-loud active galactic nuclei.
