Reverberation Mapping with Intermediate-Band Photometry: Detection of Broad-Line H Time Lags for Quasars at

Linhua Jiang, Yue Shen, Ian D. McGreer +3

We present a reverberation mapping (RM) experiment that combines broad- and intermediate-band photometry; it is the first such attempt targeting a sample of 13 quasars at $0.2<z<0.…

Now You See It, Now You Don't: The Disappearing Central Engine of the Quasar J1011+5442

Jessie C. Runnoe, Sabrina Cales, John J. Ruan +11

We report the discovery of a new "changing-look" quasar, SDSS J101152.98+544206.4, through repeat spectroscopy from the Time Domain Spectroscopic Survey. This is an addition to a s…

Towards an Understanding of Changing-Look Quasars: An Archival Spectroscopic Search in SDSS

John J. Ruan, Scott F. Anderson, Sabrina L. Cales +13

The uncertain origin of the recently-discovered `changing-looking' quasar phenomenon -- in which a luminous quasar dims significantly to a quiescent state in repeat spectroscopy ov…

The Time Domain Spectroscopic Survey: Variable Object Selection and Anticipated Results

Eric Morganson, Paul J. Green, Scott F. Anderson +37

We present the selection algorithm and anticipated results for the Time Domain Spectroscopic Survey (TDSS). TDSS is an SDSS-IV eBOSS subproject that will provide initial identifica…

Constraining the radio-loud fraction of quasars at z>5.5

E. Bañados, B. P. Venemans, E. Morganson +18

Radio-loud Active Galactic Nuclei at z~2-4 are typically located in dense environments and their host galaxies are among the most massive systems at those redshifts, providing key…
