Reverberation Mapping of the Seyfert 1 Galaxy NGC 7469
B. M. Peterson, C. J. Grier, Keith Horne +43
A large reverberation mapping study of the Seyfert 1 galaxy NGC 7469 has yielded emission-line lags for Hbeta 4861 and He II 4686 and a central black hole mass measurement of about…
The Structure of the Broad Line Region in AGN: I. Reconstructed Velocity-Delay Maps
C. J. Grier, B. M. Peterson, Keith Horne +38
We present velocity-resolved reverberation results for five active galactic nuclei. We recovered velocity-delay maps using the maximum-entropy method for four objects: Mrk 335, Mrk…
Reverberation Mapping Results for Five Seyfert 1 Galaxies
C. J. Grier, B. M. Peterson, R. W. Pogge +40
We present the results from a detailed analysis of photometric and spectrophotometric data on five Seyfert 1 galaxies observed as a part of a recent reverberation mapping program.…
The Neutral Hydrogen Bridge between M31 and M33
Felix J. Lockman, Nicole L. Free, Joseph C. Shields
The Green Bank Telescope has been used to search for 21cm HI emission over a large area between the galaxies M31 and M33 in an attempt to confirm at 9.1 arcmin angular resolution t…
A Reverberation Lag for the High-Ionization Component of the Broad Line Region in the Narrow-Line Seyfert 1 Mrk 335
C. J. Grier, B. M. Peterson, R. W. Pogge +37
We present the first results from a detailed analysis of photometric and spectrophotometric data on the narrow-line Seyfert 1 galaxy Mrk 335, collected over a 120-day span in the f…
