One prediction of ΛCDM is the existence of partially phase-mixed substructures from accreted dwarf galaxies in the Milky Way stellar halo. Substructure...
In this seminar I will focus on how the avalanche of new data changes our views on how our Galaxy formed and evolved. Precise astrometric, spectroscopic...
The Formation of Fullerenes: Clues from New C60, C70, and (Possible) Planar C24 Detections in Magellanic Cloud Planetary Nebulae
We present 10 new Spitzer detections of fullerenes in Magellanic Cloud Planetary Nebulae, including the first extragalactic detections of the C70 molecule...
All the elements from carbon to uranium present in the Solar System were produced by hundreds to thousands of stars belonging to different stellar generations...
The SUMO project: a survey of multiple populations in globular clusters
The classical idea that globular clusters are the prototypes of simple stellar populations has been revolutionized in the last few years. Multiple sequences of...
The surface of (136108) Haumea (2003 EL{61}), the largest carbon-depleted object in the trans-Neptunian belt
Context: Previously known as 2003 EL{61}, (136108) Haumea, is the largest member of a group of trans-Neptunian objects (TNOs) with similar orbits and “unique”...
The trans-Neptunian object size distribution at small sizes
Aims: The aim of this work is to estimate the size distribution of small Trans-Neptunian objects. Methods: We simulate the irradiation and collisional processes...
