The Variability of the Narrow-line Seyfert 1 Galaxies from the Pan-STARRS's View
文献摘要:
By means of the data sets from the Pan-STARRS1 survey,we have systematically examined the relationship between the variability characteristics and the physical parameters of the largest NLS1 galaxy sample up to now.The results are summarized as follows:(1).We find significant anti-correlations between variability amplitude and absolute magnitude in g,r,i,z and y bands,which are consistent with the results in previous works.(2)The correlations between the variability amplitude in optical band and many physical parameters(e.g.,λL(5100 ?),black hole mass,Eddington ratio,R4570 and R5007)are investigated.The results show the variability amplitude is significantly anti-correlated with L(5100 ?),MBH,Eddington ratio and R4570,but positively correlated with R5007.The relation could be explained by the simple standard accretion disk model.(3)We further investigate the relationship between optical variability and radio luminosity/radio-loudness.The results present weak positive correlation in g and r bands,but insignificant correlation in i,z and y bands.The large error of the approximate fraction of the host galaxy in i,z and y bands may lead to insignificant correlations.
