Swift Observations of the Highly X-ray Variable Narrow Line Seyfert 1 Galaxy Rxj0148.3–2758


We report on Swift observations of the Narrow-Line Seyfert 1 galaxy (NLS1) RX J0148.3–2758. It was observed for 41.6 ks in 2005 May and for 15.8 ks in 2005 December. On short as well as on long timescales RX J0148.3–2758 is a highly variable source. It doubles its X-ray flux within 18-25 ks. The observation of 2005 December 09, which had a flux 4 times… (More)
