The Milky Way Radial Metallicity Gradient as an Equilibrium Phenomenon: Why Old Stars are Metal-Rich
James W. Johnson, David H. Weinberg, Guillermo A. Blanc +12
Metallicities of both gas and stars decline toward large radii in spiral galaxies, a trend known as the radial metallicity gradient. We quantify the evolution of the metallicity gr…
The power spectrum of the Milky Way: Velocity fluctuations in the Galactic disk
Jo Bovy, Jonathan C. Bird, Ana E. García Pérez +3
We investigate the kinematics of stars in the mid-plane of the Milky Way on scales between 25 pc and 10 kpc with data from the Apache Point Observatory Galactic Evolution Experimen…
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 Vertical Metallicity Gradient of the Milky Way Disk: Transitions in [a/Fe] Populations
Katharine J. Schlesinger, Jennifer A. Johnson, Constance M. Rockosi +10
Using G dwarfs from the Sloan Extension for Galactic Understanding and Exploration (SEGUE) survey, we have determined a vertical metallicity gradient over a large volume of the Mil…
