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…

Oxygen, sulfur, and iron radial abundance gradients of classical Cepheids across the Galactic thin disk

R. da Silva, V. D'Orazi, M. Palla +25

Classical Cepheids (CCs) are solid distance indicators and tracers of young stellar populations. Our aim is to provide iron, oxygen, and sulfur abundances for the largest and most…

A Wide View of the Galactic Globular Cluster NGC 2808: Red Giant and Horizontal Branch Star Spatial Distributions

Christian I. Johnson, Annalisa Calamida, Justin A. Kader +7

Wide-field and deep DECam multi-band photometry, combined with HST data for the core of the Galactic globular cluster NGC 2808, allowed us to study the distribution of various stel…

Milky Way archaeology using RR Lyrae and type II Cepheids II. High velocity RR Lyrae stars, and mass of the Milky Way

Z. Prudil, A. J Koch-Hansen, B. Lemasle +10

We report the discovery of high velocity candidates among RR~Lyrae stars found in the Milky Way halo. We identified 9 RR~Lyrae stars with Galactocentric velocities exceeding the lo…

On the dwarf irregular galaxy NGC 6822. I. Young, intermediate and old stellar populations

Maria Tantalo, Massimo Dall'Ora, Giuseppe Bono +13

We present accurate and deep multi-band () photometry of the Local Group dwarf irregular galaxy NGC 6822. The images were collected with wide field cameras at 2m/4m- (INT,CT…
