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…

The GALAH survey: Tracing the Milky Way's formation and evolution through RR Lyrae stars

Valentina D'Orazi, Nicholas Storm, Andrew R. Casey +39

Stellar mergers and accretion events have been crucial in shaping the evolution of the Milky Way (MW). These events have been dynamically identified and chemically characterised us…

Shock Excitation in Narrow Line Regions Powered by AGN Outflows

Misaki Mizumoto, Hiroaki Sameshima, Naoto Kobayashi +10

Outflows in the Active Galactic Nucleus (AGN) are considered to play a key role in the host galaxy evolution through transfer of a large amount of energy. A Narrow Line Region (NLR…

A Photometric Study of the Outer Halo Globular Cluster NGC 5824

A. R. Walker, G. Andreuzzi, C. E. Martínez-Vázquez +7

Multi-wavelength CCD photometry over 21 years has been used to produce deep color-magnitude diagrams together with light curves for the variables in the Galactic globular cluster N…

Weak Galactic Halo--Fornax dSph Connection from RR Lyrae Stars

G. Fiorentino, M. Monelli, P. B. Stetson +7

For the first time accurate pulsation properties of the ancient variable stars of the Fornax dwarf spheroidal galaxy (dSph) are discussed in the broad context of galaxy formation a…

The Carina Project. X. On the kinematics of old and intermediate-age stellar populations

M. Fabrizio, G. Bono, M. Nonino +14

We present new radial velocity (RV) measurements of old (horizontal branch) and intermediate-age (red clump) stellar tracers in the Carina dwarf spheroidal. They are based on more…

On the central helium-burning variable stars of the LeoI dwarf spheroidal galaxy

G. Fiorentino, P. B. Stetson, M. Monelli +3

We present a study of short period, central helium-burning variable stars in the Local Group dwarf spheroidal galaxy LeoI, including 106 RR Lyrae stars and 51 Cepheids. So far, thi…
