Dust Reverberation Mapping and Light-Curve Modelling of Zw229-015

E. Guise, S. F. Hönig, V. Gorjian +12

Multiwavelength variability studies of active galactic nuclei (AGN) can be used to probe their inner regions which are not directly resolvable. Dust reverberation mapping (DRM) est…

The Lick AGN Monitoring Project 2011: Dynamical Modeling of the Broad-Line Region

Peter R. Williams, Anna Pancoast, Tommaso Treu +22

We present models of the H-emitting broad-line region (BLR) in seven Seyfert 1 galaxies from the Lick AGN (Active Galactic Nucleus) Monitoring Project 2011 sample, drawing infer…

Velocity-resolved reverberation mapping of five bright Seyfert 1 galaxies

G. De Rosa, M. M. Fausnaugh, C. J. Grier +99

We present the first results from a reverberation-mapping campaign undertaken during the first half of 2012, with additional data on one AGN (NGC 3227) from a 2014 campaign. Our ma…

On a new and homogeneous metallicity scale for Galactic classical Cepheids - I. Physical parameters

B. Proxauf, R. da Silva, V. V. Kovtyukh +23

We gathered more than 1130 high-resolution optical spectra for more than 250 Galactic classical Cepheids. The spectra were collected with different optical spectrographs: UVES at V…

Period Variations for the Cepheid VZ Cyg

Krittanon Sirorattanakul, Scott Engle, Joshua Pepper +4

The Cepheid Period-Luminosity law is a key rung on the extragalactic distance ladder. However, numerous Cepheids are known to undergo period variations. Monitoring, refining, and u…

On the neutron-capture elements across the Galactic thin disk using Cepheids

R. da Silva, B. Lemasle, G. Bono +19

We present new accurate abundances for five neutron-capture (Y, La, Ce, Nd, Eu) elements in 73 classical Cepheids located across the Galactic thin disk. Individual abundances are b…
