The Gaia-ESO Survey: Separating disk chemical substructures with cluster models

A. Rojas-Arriagada, A. Recio-Blanco, P. de Laverny +24

(Abridged) Recent spectroscopic surveys have begun to explore the Galactic disk system outside the solar neighborhood on the basis of large data samples. In this way, they provide…

The Chandra COSMOS Legacy survey: optical/IR identifications

S. Marchesi, F. Civano, M. Elvis +27

We present the catalog of optical and infrared counterparts of the Chandra COSMOS-Legacy Survey, a 4.6 Ms Chandra program on the 2.2 square degrees of the COSMOS field, combination…

The XMM spectral catalog of SDSS optically selected Seyfert 2 galaxies

E. Koulouridis, I. Georgantopoulos, G. Loukaidou +6

We present an X-ray spectroscopic study of optically selected (SDSS) Seyfert 2 (Sy2) galaxies. The goal is to study the obscuration of Sy2 galaxies beyond the local universe, using…

Torus mapper: a code for dynamical models of galaxies

James Binney, Paul J McMillan

We present a freely downloadable software package for modelling the dynamics of galaxies, which we call the Torus Mapper (TM). The package is based around `torus mapping', which is…

Strömgren uvby photometry of the peculiar globular cluster NGC 2419

Matthias J. Frank, Andreas Koch, Sofia Feltzing +3

NGC 2419 is a peculiar Galactic globular cluster in terms of size/luminosity, and chemical abundance anomalies. Here, we present Strömgren photometry of the cluster. Using t…

Measuring the vertical age structure of the Galactic disc using asteroseismology and SAGA

L. Casagrande, V. Silva Aguirre, K. J. Schlesinger +10

The existence of a vertical age gradient in the Milky Way disc has been indirectly known for long. Here, we measure it directly for the first time with seismic ages, using red gian…
