Description
The RL NLS1s hosting powerful relativistic jets revealed by gamma-ray emissions are very interesting. I report the discoveries of two new such objects SDSS J211852.96-073227.5 with flaring gamma-ray radiation (Hui Yang et al. 2018) and SDSS J122222.55+041315.7 with highest redshift by far (Su Yao et al. 2015a). We discuss their multi-wavelength properties and variability properties, along with the prototype 1H 0324+342 (Su Yao et al. 2015b). Moreover, we also present independent estimation on the black hole (BH) mass of the RL NLS1 1H 0324+342 using the X-ray timing method. We find a low BH mass of 10^7 Msun, which is consistent with that derived from the viral method using the optical broad emission lines.
