Pan-STARRS1 variability of XMM-COSMOS AGN. I. Impact on photometric redshifts
T. Simm, R. Saglia, M. Salvato +12
[Abbreviated] Upcoming large area sky surveys like EUCLID and eROSITA crucially depend on accurate photometric redshifts (photo-z). The identification of variable sources, such as…
The influence of galaxy surface brightness on the mass-metallicity relation
Po-Feng Wu, Rolf-Peter Kudritzki, R. Brent Tully +1
We study the effect of surface brightness on the mass-metallicity relation using nearby galaxies whose gas content and metallicity profiles are available. Previous studies using fi…
A Three-Dimensional Map of Milky-Way Dust
Gregory M. Green, Edward F. Schlafly, Douglas P. Finkbeiner +13
We present a three-dimensional map of interstellar dust reddening, covering three-quarters of the sky out to a distance of several kiloparsecs, based on Pan-STARRS 1 and 2MASS phot…
The Globular Cluster System of NGC 6822
J. Veljanoski, A. M. N. Ferguson, A. D. Mackey +11
We present a comprehensive analysis of the globular cluster (GC) system of the Local Group dwarf irregular galaxy NGC 6822. Our study is based on homogeneous optical and near-IR ph…
Massive Stars in the W33 Giant Molecular Complex
Maria Messineo, J. Simon Clark, Donald F. Figer +9
Rich in HII regions, giant molecular clouds are natural laboratories to study massive stars and sequential star formation. The Galactic star forming complex W33 is located at l=~12…
Red Supergiants as Cosmic Abundance Probes: The Sculptor Galaxy NGC 300
J. Zachary Gazak, Rolf Kudritzki, Chris Evans +9
We present a quantitative spectroscopic study of twenty-seven red supergiants in the Sculptor Galaxy NGC 300. J-band spectra were obtained using KMOS on the VLT and studied with st…
