Comparing Optical Variability of Type 1 and Type 2 AGN from the BAT 9-Month Sample using ASAS-SN and TESS Surveys

Natalie Kovacevic, Xinyu Dai, Heechan Yuk +6

We present an optical variability analysis and comparison of the samples of Seyfert 1 and 2 galaxies, selected from the \textit{Swift} 9-month BAT catalog, using the light curves f…

Swift Monitoring Observations of Mrk 231: Detection of Ultraviolet Variability

Lilan Yang, Xinyu Dai, Youjun Lu +2

We analyze 168 Swift monitoring observations of the nearest broad absorption line quasar Mrk 231 in the UV and X-ray bands, where we detect significant variability in the UV ($\sim…

Unveiling the Intrinsic X-ray Properties of Broad Absorption Line Quasars with a Relatively Unbiased Sample

Leah K. Morabito, Xinyu Dai, Karen M. Leighly +2

There is growing evidence of a higher intrinsic fraction of broad absorption line quasars (BALQSOs) than that obtained in optical surveys, on which most previous X-ray studies of B…

Suzaku Observations of Three FeLoBAL QSOs, SDSS J0943+5417, J1352+4239, and J1723+5553

Leah K. Morabito, Xinyu Dai, Karen M. Leighly +2

We present Suzaku observations of three iron low-ionization broad absorption line quasars (FeLoBALs). We detect J1723+5553 (3σ) in the observed 2--10 keV band, and constrain its in…

The Intrinsic Fractions and Radio Properties of Low Ionization Broad Absorption Line Quasars

Xinyu Dai, Francesco Shankar, Gregory R. Sivakoff

Low-ionization (MgII, FeII, FeIII) broad absorption line quasars (LoBALs) probe a relatively obscured quasar population, and could be at an early evolutionary stage for quasars. We…

Dependence of the BALQSO fraction on Radio Luminosity

Francesco Shankar, Xinyu Dai, Gregory R. Sivakoff

We find that the fraction of classical Broad Absorption Line quasars (BALQSOs) among the FIRST radio sources in the Sloan Data Release 3, is 20.5^{+7.3}_{-5.9}% at the faintest rad…

2MASS Reveals a Large Intrinsic Fraction of BALQSOs

Xinyu Dai, Francesco Shankar, Gregory R. Sivakoff

The intrinsic fraction of broad absorption line quasars (BALQSOs) is important in constraining geometric and evolutionary models of quasars. We present the fraction of BALQSOs in 2…
