Estimating Black Hole Masses in Hundreds of Quasars
Nina Hernitschek, Hans-Walter Rix, Jo Bovy +1
We explore the practical feasibility of AGN broad-band reverberation mapping and present first results. We lay out and apply a rigorous approach for stochastic reverberation mappin…
Young alpha-enriched giant stars in the solar neighbourhood
Marie Martig, Hans-Walter Rix, Victor Silva Aguirre +31
We derive age constraints for 1639 red giants in the APOKASC sample for which seismic parameters from Kepler, as well as effective temperatures, metallicities and [alpha/Fe] values…
On the importance of using appropriate spectral models to derive physical properties of galaxies at 0.7<z<2.8
Camilla Pacifici, Elisabete da Cunha, Stéphane Charlot +14
Interpreting observations of distant galaxies in terms of constraints on physical parameters - such as stellar mass, star-formation rate (SFR) and dust optical depth - requires spe…
3D Dust Mapping Reveals that Orion Forms Part of a Large Ring of Dust
E. F. Schlafly, G. Green, D. P. Finkbeiner +12
The Orion Molecular Complex is the nearest site of ongoing high-mass star formation, making it one of the most extensively studied molecular complexes in the Galaxy. We have develo…
Tracing chemical evolution over the extent of the Milky Way's Disk with APOGEE Red Clump Stars
David L. Nidever, Jo Bovy, Jonathan C. Bird +40
We employ the first two years of data from the near-infrared, high-resolution SDSS-III/APOGEE spectroscopic survey to investigate the distribution of metallicity and alpha-element…
Gaia-ESO Survey: The analysis of high-resolution UVES spectra of FGK-type stars
R. Smiljanic, A. J. Korn, M. Bergemann +99
The Gaia-ESO Survey is obtaining high-quality spectroscopic data for about 10^5 stars using FLAMES at the VLT. UVES high-resolution spectra are being collected for about 5000 FGK-t…
