【摘要】:正The compact radio structure of radio-loud NLS1s顾敏峰上海天文台We present the compact radio structure of four radio-loud narrow line Seyfert 1 galaxies from VLBA archive data at 1.6,2.3,5 and 8.4 GHz.Three out of four sources are unresolved or slightly resolved in milliarcsecond resolutions,and the remaining one is resolved into core-jet structures at 1.6 and 5 GHz. From the high resolution VLBI radio data,two sources have fiat spectrum between 1.6 and 5 GHz
