On the Use of Field RR Lyrae as Galactic Probes -- VIII. Early Formation of the Galactic Spheroid
G. Bono, V. F. Braga, M. Fabrizio +54
We introduce a new photometric catalog of RR Lyrae variables (RRLs, 300,000) mainly based on data available in public datasets. We also present the largest and most homogeneo…
Classical Cepheids in the Galactic thin disk I. Abundance gradients via non-local thermodynamic equilibrium spectral analysis
Antonino Nunnari, Valentina D'Orazi, Giuliana Fiorentino +23
Classical Cepheids (CCs) have long been considered excellent tracers of the chemical evolution of the Milky Way's young disk. We present a homogeneous, NLTE spectroscopic analysis…
Physical properties of the first spectroscopically confirmed red supergiant stars in the Sculptor Group galaxy NGC 55
L. R. Patrick, C. J. Evans, B. Davies +5
We present K-band Multi-Object Spectrograph (KMOS) observations of 18 Red Supergiant (RSG) stars in the Sculptor Group galaxy NGC 55. Radial velocities are calculated and are shown…
The Pan-STARRS1 distant z>5.6 quasar survey: more than 100 quasars within the first Gyr of the universe
E. Bañados, B. P. Venemans, R. Decarli +33
Luminous quasars at z>5.6 can be studied in detail with the current generation of telescopes and provide us with unique information on the first gigayear of the universe. Thus far…
The host galaxy and late-time evolution of the Super-Luminous Supernova PTF12dam
T. -W. Chen, S. J. Smartt, A. Jerkstrand +14
Super-luminous supernovae of type Ic have a tendency to occur in faint host galaxies which are likely to have low mass and low metallicity. PTF12dam is one of the closest and best…
A Map of Dust Reddening to 4.5 kpc from Pan-STARRS1
E. F. Schlafly, G. Green, D. P. Finkbeiner +17
We present a map of the dust reddening to 4.5 kpc derived from Pan-STARRS1 stellar photometry. The map covers almost the entire sky north of declination -30 degrees at a resolution…
Young Massive Clusters/Associations in the GMC G23.3-0.3
M. Messineo, K. M. Menten, D. Figer +7
An overview of a spectroscopic survey for massive stars in the direction of the Galactic giant molecular complex G23.3-0.3 is presented (Messineo et al. 2010, and 2014 A&A submitte…
First Results from Pan-STARRS1: Faint, High Proper Motion White Dwarfs in the Medium-Deep Fields
J. L. Tonry, C. W. Stubbs, M. Kilic +13
The Pan-STARRS1 survey has obtained multi-epoch imaging in five bands (Pan-STARRS1 gps, rps, ips, zps, and yps) on twelve "Medium Deep Fields", each of which spans a 3.3 degree cir…
Massive stars in the Cl 1813-178 Cluster. An episode of massive star formation in the W33 complex
Maria Messineo, Ben Davies, Donald F. Figer +5
Young massive (M >10^4 Msun) stellar clusters are a good laboratory to study the evolution of massive stars. Only a dozen of such clusters are known in the Galaxy. Here we report a…
