The recurrent impact of the Sagittarius dwarf on the Milky Way star formation history
The measurement of distances to individual stars with Gaia is enabling the construction of deep colour-magnitude diagrams (CMD) for large volumes within our...
The relation between bar formation, galaxy luminosity, and environment.
We derive the bar fraction in three different environments ranging from the field to Virgo and Coma clusters, covering an unprecedentedly large range of galaxy...
The Relation Between Stellar Populations and Light Profiles in Early-Type Galaxies
Early-type (E/SO) galaxies follow tight relations such as the Fundamental Plane, the Color-Magnitude Relation or the Mg2-σ relation (Bender et al. 1992)...
The relation between the sérsic law shape along major and minor axes of elliptical galaxies
In this paper we discuss the reason for the widely found discrepancy between Sérsic brightness law fitted along major and minor axes of elliptical galaxies. We...
The relation of the abundance ratios in early-type galaxies with the cluster mass
We present the values of CN and Mg overabundances with respect to Fe, for early-type galaxies in 8 clusters over a range of richness and morphology. Spectra...
The Relative Ages of LMC Old Clusters and the Case of NGC 1841
Using archival HST/WFPC2 imaging of 7 LMC globular clusters, and following the methods outlined in our previous study, we have reached the tightest constrain so...
The relative role of AGB stars and SNe as the first cosmic dust polluters
Far infrared and sub-millimeter observations of quasars and normal star forming galaxies at z>6 have revealed the presence of large amounts of dust. At such...
The Remote Observing Working Group for the Asteroid Impact and Deflection Assessment (AIDA)
The Asteroid Impact and Deflection Assessment (AIDA) is a joint US-European mission concept designed to demonstrate the effectiveness of an kinetic impactor for...
