We present Stromgren and near-infrared (NIR) photometry of the bulge cluster NGC 6528 and its surrounding field in the Ba ade's Window. uvby images have been collected with EFOSC2 on the New Technology Telescope (NTT, La Silla, ESO). The NIR catalogs are based on J, K-band VIRCAM@VISTA (Paranal, ESO) and SOFI@NTT photometry . The matching of the aforementioned data sets with Hubble Space Telescope photometry allowed us to obtain proper-motion-cleaned samples of NGC 6528 and bulge stars… 
Near-infrared photometry of globular clusters towards the Galactic bulge: observations and photometric metallicity indicators
We present wide field JHKs photometry of 16 Galactic globular clusters located towards the Galactic bulge, calibrated on the 2MASS photometric system. Differential reddening corrections and
A Panchromatic View of the Bulge Globular Cluster NGC 6569
We used high-resolution optical Hubble Space Telescope/WFC3 and multiconjugate adaptive optics assisted GEMINI GeMS/Gemini South Adaptive Optics Imager observations in the near-infrared (NIR) to
Infrared photometry and CaT spectroscopy of globular cluster M 28 (NGC 6626)
Context. Recent studies show that the inner Galactic regions host genuine bulge globular clusters, but also halo intruders, complex remnants of primordial building blocks, and objects likely accreted
Comparing Observed Stellar Kinematics and Surface Densities in a Low-latitude Bulge Field to Galactic Population Synthesis Models
We present an analysis of Galactic bulge stars from Hubble Space Telescope Wide Field Camera 3 observations of the Stanek window (l, b = [0.25, −2.15]) from two epochs approximately two years apart.

Project AMIGA: Distance and Metallicity Gradients along Andromeda’s Giant Southern Stream from the Red Clump
The Giant Southern Stream (GSS) of M31, a keystone signature of a major accretion event, yields crucial constraints on M31 formation and evolution models. Currently, our understanding of the GSS, in
APOGEE chemical abundances of globular cluster giants in the inner Galaxy
We report chemical abundances obtained by Sloan Digital Sky Survey (SDSS)-III/Apache Point Observatory Galactic Evolution Experiment for giant stars in five globular clusters located within 2.2 kpc
Search for an Intrinsic Metallicity Spread in Old Globular Clusters of the Large Magellanic Cloud
We report for the first time on the magnitude of the intrinsic [Fe/H] spread among 10 old globular clusters (GCs) of the Large Magellanic Cloud (LMC). Such spreads are merely observed in
Strömgren metallicities for intermediate-age and old star clusters
We report results that show that the straightforward star cluster metallicities obtained from Strömgren vby photometry are age-dependent and need to be corrected for further use. This outcome arises
The Milky Way without X: An alternative interpretation of the double red clump in the Galactic bulge
The presence of two red clumps (RCs) in high latitude fields of the Milky Way bulge is interpreted as evidence for an X-shaped structure originated from the bar instability. Here we show, however,
