Description
We report preliminary results of the observations performed by the Neil Gehrels Swift Observatory on SDSS J102906. 69+ 555625.2 (z= 0.451) and SDSS J152205. 41+ 393441.3 (z= 0.077), two narrow-line Seyfert 1 galaxies detected at 37 GHz (Lahteenmaki et al, 2018, A & A, 614, L1; Berton et al. 2020, A & A 636, A64) for which only 3 sigma ULs (ROSAT, 0.2-2 keV) were previously available at about 3E-13 erg/cm2/s and 2E-13 erg/cm2/s, respectively.
