| dc.description | The narrow-line Seyfert 1 galaxy (NLS1) IRAS 13224-3809 has been observed with the CHANDRA High Resolution Camera (HRC-I) for 12 ksec on February, 2, 2000. The source was proposed for CHANDRA observations to precisely determine the X-ray centroid position and to investigate the timing properties of the most X-ray variable Seyfert galaxy. The position derived from CHANDRA confirms that the X-ray emission is associated with IRAS 13224-3809. The CHANDRA HRC-I light curve shows indications for a possible presence of a quasi-periodic oscillation. The strongest signal is found at 2500 sec. Accretion disk instabilities may provide a plausible explanation for the quasi-periodic oscillations. | |
