Early Results from the KELT Transit Survey
Joshua Pepper, Richard Pogge, D. L. DePoy +5
The Kilodegree Extremely Little Telescope (KELT) project is a small-aperture transit survey of bright stars. The project has completed commissioning runs searching for transits in…
The Mass of the Black Hole in the Seyfert 1 Galaxy NGC 4593 from Reverberation Mapping
Kelly D. Denney, Misty C. Bentz, Bradley M. Peterson +15
We present new observations leading to an improved black hole mass estimate for the Seyfert 1 galaxy NGC 4593 as part of a reverberation-mapping campaign conducted at the MDM Obser…
The Tully-Fisher Relation and Its Residuals for a Broadly Selected Sample of Galaxies
James Pizagno, Francisco Prada, David H. Weinberg +7
We measure the relation between galaxy luminosity and disk circular velocity (the Tully-Fisher [TF] relation), in the g, r, i, and z-bands, for a broadly selected sample of galaxie…
A Reverberation-Based Mass for the Central Black Hole in NGC 4151
Misty C. Bentz, Kelly D. Denney, Edward M. Cackett +15
We have undertaken a new ground-based monitoring campaign to improve the estimates of the mass of the central black hole in NGC 4151. We measure the lag time of the broad H beta li…
Chandra Observations of Candidate "True" Seyfert 2 Nuclei
Himel Ghosh, Richard W. Pogge, Smita Mathur +2
The Unification Model for active galactic nuclei posits that Seyfert 2s are intrinsically like Seyfert 1s, but that their broad-line regions (BLRs) are hidden from our view. A Seyf…
Protecting Life in the Milky Way: Metals Keep the GRBs Away
K. Z. Stanek, O. Y. Gnedin, J. F. Beacom +7
The host galaxies of the five local, z<0.25, long-duration gamma-ray bursts, each of which had a well-documented associated supernova, are all faint and metal-poor compared to the…
