Examples of Absorption Line in a sentence
The spectroscopic classifica- tions, especially the AGN-classifications, derive from analysis with the Gas AND Absorption Line Fitting (GANDALF) code (Cappellari & Emsellem 2004; Sarzi et al.
SPANSAT: Program for Calculating the LTE Absorption Line Profiles in Stellar Atmospheres, Kyiv, 1988, Inst.
We measured the stellar and ionized-gas kinematics of NGC 4264 from the sky-cleaned datacube of the galaxy using the Penalized Pixel Fitting (PPXF; Cappellari & Emsellem 2004) and with the Gas and Absorption Line Fitting (GANDALF; Sarzi et al.

Absorption Line Fit Parameters (Component V and b in km s−1,N in 10−10 cm−2).
To further mimic the DR9 selection, we then replace the automated catalogs of Broad Absorption Line quasars and Damped Lyman-α systems by the visual catalogs that were used in DR9.
Broad Absorption Line (BAL) QSOs are a particular and not yet understood class of AGN: their spectra show wide troughs towards the blue wing of some UV emission lines (Mg ii, Al iii, Si iv, C iv), due to ionized gas with outflow velocities up to 0.2 c.
However, five out of the seven sources are classi- fied as Broad Absorption Line (BAL) quasars in the DR12 SDSS catalogue 4.
Mrk 231, at a redshift of 0.04217, is a well-studied Seyfert type 1 galaxy (Sanders et al., 1988; Surace et al., 1998) and a Broad Absorption Line Quasi-Stellar Object (BALQSO; Boksenberg et al., 1977; Smith et al., 1995; Gallagher et al., 2002).
We present the cross-correlation and baseline fit results in section 5.1, we explore any redshift evolution of the redshift error parameter in section 5.2, and the impact of Broad Absorption Line regions in section 5.3. We address the redshift dependent bias on the quasar templates in section 6.
