Massive stars are those with more than ~8 solar masses, the limit above which stars may undergo a core collapse supernova (SN) explosion at the end of its life. They have played a critical role in how the Universe has evolved and to understand this role we need to know the physics ruling them and the evolutionary paths they follow. In the last

The investigation of near Earth Objects (NEOs) can provide crucial information on the formation and early evolution of the solar system and is also important to constrain the asteroidal contribution to the delivery of prebiotic material (water and organic molecules) to our planet (e.g., Pierazzo and Chyba, 1999; Morbidelli et al., 2000; Saladino et

The Sun, our star, is not only the source of the electromagnetic radiation that bathes our planet; it also sweeps the Earth's magnetosphere with its wind and heliospheric magnetic field. It frequently sends huge ropes of magnetized plasma, the coronal mass ejections, that can hit us and cause solar storms, thus constituting a serious potential

The Universe's re-ionisation is at the forefront of research. How the re-ionisation occurred is however still not known. This project intents to understand the mechanisms that produce the reionsation. Besides it deals with the most active sources that take part in the re-ionisation. In this project we will emphasised the study of LAEs with double

Starsbursts play a key role in the cosmic evolution of galaxies. There is an intimate link between the average star formation (SF) rate history of the universe and galaxy mass and metal content. This fact, together with the prevalence of the extreme SF conditions in the primeval galaxy population, tells us that the starburst phenomenon constitutes
