The Early Data Release of the Sloan Digital Sky Survey (SDSS) contains 150Narrow-Line Seyfert 1 (NLS1) galaxies, most of them previously unknown. Wepresent here the study of the X-ray emission from two of these active galaxies(SDSS J030639.57+000343.2 and SDSS J141519.50-003021.6), based upon XMM-Newtonobservations. The spectral and timing characteristics of the two sources arepresented and compared against the typical properties of known NLS1 galaxies.We found that these two NLS1 are within the dispersion range of the typicalvalues of this class of AGN, although with some interesting features thatdeserve further studies.Comment: 5 pages, 8 figures. Accepted for publication on A&A Main Journa
