Classical Cepheids in the Nuclear Stellar Disk: membership via dynamical analysis
M. De Leo, M. Zoccali, R. Albarracin +2
(abridged) Four classical Cepheids have been associated to the Nuclear Stellar Disk (NSD), suggesting a burst of star formation 20 Myrs ago. In this work, we analyse all available…
The Hubble Missing Globular Clusters Survey IV. Ultra-faint compact satellites of the Milky Way. The case of Koposov 2
M. Bellazzini, R. Pascale, E. Dodd +16
In the last decades a number of extremely faint and compact Galactic satellites (Ultra Faint Compact Satellites; UFCS) have been discovered by large panoramic surveys. Their nature…
Spectroscopic metallicities and first α-element abundances of RR Lyrae stars in Baade's Window
J. Olivares Carvajal, Á. Rojas-Arriagada, M. Zoccali +10
RR Lyrae stars in the bulge have been reported to be associated with the spheroidal, relatively metal-poor component. They offer a way to trace this component with precise distance…
Low-resolution spectroscopic characterisation of five poorly known Galactic stellar clusters
E. Ceccarelli, M. Bellazzini, D. Massari +4
Stellar clusters preserve crucial information on the formation and evolutionary processes that shaped the Milky Way (MW) as we see it today. However, several MW clusters still lack…
VVV catalog of ab-type RR Lyrae in the inner Galactic bulge
M. Zoccali, C. Quezada, R. Contreras Ramos +7
Context. Observational evidence has accumulated in the past years, showing that the Galactic bulge includes two populations, a metal poor and a metal rich one that, in addition to…
Comparing bulge RR Lyrae stars with bulge giants -- Insight from 3D kinematics
J. Olivares Carvajal, M. Zoccali, M. De Leo +6
The structure and kinematics of the old component of the Galactic bulge are still a matter of debate. The bulk of the bulge as traced by red clump stars includes two main component…
The treasure behind the haystack: MUSE analysis of five recently discovered globular clusters
F. Gran, G. Kordopatis, M. Zoccali +10
After the second data release of Gaia, the number of new globular cluster candidates has increased importantly. However, most of them need to be properly characterised, both spectr…
Surviving the Waves: evidence for a Dark Matter cusp in the tidally disrupting Small Magellanic Cloud
Michele De Leo, Justin I. Read, Noelia E. D. Noel +3
We use spectroscopic data for Red Giant Branch (RGB) stars in the Small Magellanic Cloud (SMC), together with proper motion data from \textit{Gaia} Early Data Release…
Revealing the tidal scars of the Small Magellanic Cloud
Michele De Leo, Ricardo Carrera, Noelia E. D. Noel +3
Due to their close proximity, the Large and Small Magellanic Clouds (SMC/LMC) provide natural laboratories for understanding how galaxies form and evolve. With the goal of determin…
On the nature of a shell of young stars in the outskirts of the Small Magellanic Cloud
David Martinez-Delgado, A. Katherina Vivas, Eva K. Grebel +35
Understanding the evolutionary history of the Magellanic Clouds requires an in-depth exploration and characterization of the stellar content in their outer regions, which ultimatel…
Frontier Fields : Combining HST, VLT and Spitzer data to explore the 8 Universe behind the lensing cluster MACS04162403
N. Laporte, A. Streblyanska, S. Kim +7
(Abridged) The HST Frontier Fields project started at the end of 2013 with the aim of providing extremely deep images of 6 massive galaxy clusters. One of the main goals of this pr…
