The First HeI*λ10830 BALQSO
Karen M. Leighly, Matthias Dietrich, Sara Barber
We report the discovery of the first HeI*λ10830 broad absorption line quasar FBQS J1151+3822. Using new infrared and optical spectra, as well as the SDSS spectrum, we extracted the…
The First Ultra-Cool Brown Dwarf Discovered by the Wide-field Infrared Survey Explorer
A. Mainzer, Michael C. Cushing, M. Skrutskie +17
We report the discovery of the first new ultra-cool brown dwarf found with the Wide-field Infrared Survey Explorer (WISE). The object's preliminary designation is WISEPC J045853.90…
Black Hole Mass Estimates Based on CIV are Consistent with Those Based on the Balmer Lines
R. J. Assef, K. D. Denney, C. S. Kochanek +39
Using a sample of high-redshift lensed quasars from the CASTLES project with observed-frame ultraviolet or optical and near-infrared spectra, we have searched for possible biases b…
Reverberation Mapping Measurements of Black Hole Masses in Six Local Seyfert Galaxies
K. D. Denney, B. M. Peterson, R. W. Pogge +40
We present the final results from a high sampling rate, multi-month, spectrophotometric reverberation mapping campaign undertaken to obtain either new or improved Hbeta reverberati…
