A Spitzer-MIPS search for dust in compact high-velocity HI clouds
Rik J. Williams, Smita Mathur, Shawn Poindexter +2
We employ three-band Spitzer-MIPS observations to search for cold dust emission in three neutral hydrogen compact high-velocity clouds (CHVCs) in the vicinity of the Milky Way. Far…
Whole Earth Telescope Observations of the subdwarf B star KPD 1930+2752: A rich, short period pulsator in a close binary
M. D. Reed, S. L. Harms, S. Poindexter +58
KPD 1930+2752 is a short-period pulsating subdwarf B (sdB) star. It is also an ellipsoidal variable with a known binary period just over two hours. The companion is most likely a w…
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…
Microlensing Evidence That A Type 1 Quasar Is Viewed Face On
Shawn Poindexter, Christopher S. Kochanek
Using a microlensing analysis of 11-years of OGLE V-band photometry of the four image gravitational lens Q2237+0305, we measure the inclination i of the accretion disk to be cos i…
The Transverse Peculiar Velocity of the Q2237+0305 Lens Galaxy and the Mean Mass of Its Stars
Shawn Poindexter, Christopher S. Kochanek
Using 11-years of OGLE V-band photometry of Q2237+0305, we measure the transverse velocity of the lens galaxy and the mean mass of its stars. We can do so because, for the first ti…
Diverse Broad Line Region Kinematic Signatures From Reverberation Mapping
K. D. Denney, B. M. Peterson, R. W. Pogge +40
A detailed analysis of the data from a high sampling rate, multi-month reverberation mapping campaign, undertaken primarily at MDM Observatory with supporting observations from tel…
