内容記述タイプ Abstract
内容記述 We present a high-resolution spectrum of the quasar HS 1603+ 3820 (z(em) = 2.542), observed with the High Dispersion Spectrograph on the Subaru Telescope. This quasar, first discovered in the Hamburg/CfA Quasar Survey, has 11 C IV lines at 1.96 < z(abs) < 2.55. Our spectrum covers eight of the 11 C IV lines at z(abs) > 2.29 and resolves some of them into multiple narrow components with b < 25 km s(-1) because of the high spectral resolution R = 45,000, while other lines show broad profiles (b > 65 km s(-1)). We use three properties of C IV lines, specifically, time variability, covering factor, and absorption-line profile, to classify them into quasar intrinsic absorption lines ( QIALs) and spatially intervening absorption lines (SIALs). The C IV lines at 2.42 < z(abs) < 2.45 are classified as QIALs in spite of their large velocity shifts from the quasar. Perhaps they are produced by gas clouds ejected from the quasar with velocity v(ej) = 8000-10,000 km s(-1). On the other hand, three C IV lines at 2.48 < z(abs) < 2.55 are classified as SIALs, which suggests there exist intervening absorbers near the quasar. We, however, cannot rule out QIALs for the two lines at z(abs) similar to 2.54 and 2.55, because their velocity shifts, 430 km s(-1) blueward and 950 km s(-1) redward of the quasar, are very small. The C IV line at z(abs) similar to 2.48 consists of many narrow components and also has corresponding low-ionization metal lines (Al II Si II and Fe II). The velocity distribution of these low-ionization ions is concentrated at the center of the system compared with that of the high-ionization C IV ion. Therefore we ascribe this system of absorption lines to an intervening galaxy.
