We present the first results from a reverberation-mapping campaign undertaken during the first half of 2012, with additional data on one AGN (NGC 3227) from a 2014 campaign. Our main goals are (1) to determine the black hole masses from continuum-Hbe

Orbital, Superhump, and Superorbital Periods in the Cataclysmic Variables AQ Mensae and IM Eridani

Autor: Armstrong, E., Patterson, J., Michelsen, E., Thorstensen, J., Uthas, H., Vanmunster, T., Hambsch, F. -J., Roberts, G., Dvorak, S.

We report photometric detections of orbital and superorbital signals, and negative orbital sidebands, in the light curves of the nova-like cataclysmic variables AQ Mensae and IM Eridani. The frequencies of the orbital, superorbital, and sideband sign

We obtained 98 R-band and 18 B, r', i' images of the optical afterglow of GRB 060526 (z=3.21) with the MDM 1.3m, 2.4m, and the PROMPT telescopes in Cerro Tololo over the 5 nights following the burst trigger. Combining these data with other optical ob

High Speed Photometry of SDSS J013701.06-091234.9

Autor: Pretorius, M. L., Woudt, P. A., Warner, B., Bolt, G., Patterson, J., Armstrong, E.

We present high speed photometry of the Sloan Digital Sky Survey cataclysmic variable SDSS J013701.06-091234.9 in quiescence and during its 2003 December superoutburst. The orbital modulation at 79.71\pm0.01 min is double humped; the superhump period
