Syntriod: A Robust Initial Parameter Estimator for Radial Velocity Curve Solutions Beyond Conventional Sampling Limits
Emre Barbaros, Hasan Ak, N. Filiz Ak
We present Syntriod, an orbital-phase domain radial velocity (RV) template-based algorithm designed to provide robust initial orbital parameter estimates for spectroscopic binaries…
The Seventeenth Data Release of the Sloan Digital Sky Surveys: Complete Release of MaNGA, MaStar and APOGEE-2 Data
Abdurro'uf, Katherine Accetta, Conny Aerts +337
This paper documents the seventeenth data release (DR17) from the Sloan Digital Sky Surveys; the fifth and final release from the fourth phase (SDSS-IV). DR17 contains the complete…
Variability of Low-ionization Broad Absorption Line Quasars Based on Multi-epoch Spectra from The Sloan Digital Sky Survey
Weimin. Yi, W. N. Brandt, P. B. Hall +5
We present absorption variability results for 134 bona fide \mgii\ broad absorption line (BAL) quasars at 0.46~~2.3 covering days to 10 yr in the rest f…
Broad absorption line disappearance/emergence in multiple ions in a weak emission-line quasar
Weimin Yi, M. Vivek, W. N. Brandt +9
We report the discovery of disappearance of Mg ii, Al iii, C iv, and Si iv broad absorption lines (BALs) at the same velocity, accompanied by a new Civ BAL emerging at a higher vel…
X-ray and multi-epoch optical/UV investigations of BAL to non-BAL quasar transformations
Sameer, W. N. Brandt, S. Anderson +10
We report on an X-ray and optical/UV study of eight Broad Absorption Line (BAL) to non-BAL transforming quasars at 1.7-2.2 over 0.29-4.95 rest-frame years with at lea…
Emergence and Variability of Broad Absorption Line Quasar Outflows
Jesse A. Rogerson, Patrick B. Hall, Nabeel S. Ahmed +3
We isolate a set of quasars that exhibit emergent C iv broad absorption lines (BALs) in their spectra by comparing spectra in the SDSS Data Release 7 and the SDSS/BOSS Data Release…
