两类Seyfert星系的黑洞质量与吸积率

收集了89个Seyfert星系样本,利用反响映射法和恒星弥散速度法计算了Seyfert星系的黑洞质量,分别研究了Seyfert 1和Seyfert 2星系的黑洞质量与吸积率、热光度和红移之间的相关性,结果发现Seyfert 1星系的黑洞质量与吸积率、热光度和红移之间具有强相关性,Seyfert 2星系的黑洞质量与吸积率之间具有弱的负相关性,与热光度和红移之间具有弱相关性.两类Seyfert星系的区别除了源于吸积盘倾角不同外,还可能与星系的环境、演化和星系核的活动有关.

Black Hole Mass and Accretion Rate of Two Types of Seyfert Galaxies

In this paper,we collected 89 samples of Seyfert galaxies,calculated the black hole mass of Seyfert galaxies using the reverberation mapping method and the central velocity dispersion respectively,and studied the correlation between the black hole mass of Seyfert 1and Seyfert 2galaxies,accretion rate,bolometric luminosity and the redshift.There are strong correlations between black hole mass of Seyfert 1and accretion rate,between the black hole mass of Seyfert 1and the bolometric luminosity,and between the black hole mass of Seyfert 1and the redshift,while there are weak negative correlation between the black hole mass of Seyfert 2and the accretion rate,weak correlation between the black hole mass of Seyfert 2and the bolometric luminosity,and between the black hole mass of Seyfert 2and the redshift.The differences between the two kinds of Seyfert galaxies not only be due to the different aspect angles,may also be due to the environment,the evolution of galaxies and activities of galaxies nuclear.
