The Time-Domain Spectroscopic Survey: Radial Velocity Variability in Dwarf Carbon Stars
Benjamin R. Roulston, Paul J. Green, John J. Ruan +6
Dwarf carbon (dC) stars, main sequence stars showing carbon molecular bands, were initially thought to be an oxymoron since only AGB stars dredge carbon into their atmospheres. Mas…
Changing-Look Quasar Candidates: First Results from Follow-up Spectroscopy of Highly Optically Variable Quasars
Chelsea L. MacLeod, Paul J. Green, Scott F. Anderson +15
Active galactic nuclei (AGN) that show strong rest-frame optical/UV variability in their blue continuum and broad line emission are classified as "changing-look" AGN, or at higher…
The Type I Superluminous Supernova PS16aqv: Lightcurve Complexity and Deep Limits on Radioactive Ejecta in a Fast Event
P. K. Blanchard, M. Nicholl, E. Berger +6
[Abridged] We present UV/optical observations of PS16aqv (SN 2016ard), a Type I superluminous supernova (SLSN-I) classified as part of our search for low- SLSNe. PS16aqv is a fa…
The Sloan Digital Sky Survey Quasar Catalog: Fourteenth Data Release
I. Pâris, P. Petitjean, E. Aubourg +38
We present the Data Release 14 Quasar catalog (DR14Q) from the extended Baryon Oscillation Spectroscopic Survey (eBOSS) of the Sloan Digital Sky Survey IV (SDSS-IV). This catalog i…
