The Nature of the Variable Galactic Center Source IRS16SW
D. L. DePoy, J. Pepper, Richard W. Pogge +3
We report measurements of the light curve of the variable Galactic Center source IRS16SW. The light curve is not consistent with an eclipsing binary or any other obvious variable s…
Central Masses and Broad-Line Region Sizes of Active Galactic Nuclei. II. A Homogeneous Analysis of a Large Reverberation-Mapping Database
B. M. Peterson, L. Ferrarese, K. M. Gilbert +9
We present improved black hole masses for 35 active galactic nuclei (AGNs) based on a complete and consistent reanalysis of broad emission-line reverberation-mapping data. From obj…
Supermassive Black Holes in Active Galactic Nuclei. II. Calibration of the M-sigma Relationship for AGNs
Christopher A. Onken, Laura Ferrarese, David Merritt +5
We calibrate reverberation-based black hole masses in active galactic nuclei (AGNs) by using the correlation between black hole mass, M, and bulge/spheroid stellar velocity dispers…
Super-solar N/C in the NLS1 Galaxy Markarian 1044
Dale L. Fields, Smita Mathur, Richard W. Pogge +2
Narrow-Line Seyfert 1s (NLS1s) are known to have extreme values of a number of properties compared to Active Galactic Nuclei (AGN) as a class. In particular, previous emission-line…
Potential Direct Single-Star Mass Measurement
H. Ghosh
We analyze the lightcurve of the microlensing event OGLE-2003-BLG-175/MOA-2003-BLG-45 and show that it has two properties that, when combined with future high resolution astrometry…
OGLE-2003-BLG-238: Microlensing Mass Estimate of an Isolated Star
Guangfei Jiang, D. L. DePoy, A. Gal-Yam +38
Microlensing is the only known direct method to measure the masses of stars that lack visible companions. In terms of microlensing observables, the mass is given by M=(c^2/4G)\tild…
