The Variability of the Narrow-line Seyfert 1 Galaxies from the Pan-STARRS’s View

Abstract: 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… Show more

“…found significantly positive correlation at lower redshift (z<0.4) between the variability amplitude and luminosity at 5100 Å, but significant anti-correlation at higher redshift (0.4 < z <0.8). Wang et al (2022) analyzed the relationship of the 11101 NLS1 galaxies from Pan-STARRS which showed mild anti-correlation. Compared with aforementioned results, the insignificant correlation between variability amplitude and luminosity in lower redshift are needed to further investigate again in the future.…”
