This book provides a unique view of Astronomy in Culture, Archaeoastronomy and Ethnoastronomy involving ancient civilizations in Latin America, emphasizing scientific and cultural knowledge combined with historical, cognitive, archaeological and anthropological aspects. Topics covered in the book include different associations of ancient civilizations with the stars and planets, whether in farming, architecture, social organization, beliefs, myths, religion, metric systems, calendar construction, shrines, and variations in astronomical research methods based on the types of material evidence available. Special attention is paid to the war cycles associated with observed celestial events, day-counting calendars, including movements in the sky and written evidences from codices, and in particular the Andean and Inca traditions of astronomically associated shrines, caves and celestial alignments of monuments and temples.

Recent discoveries in astronomy and relativistic astrophysics as well as experiments on particle and nuclear physics have blurred the traditional boundaries of physics. It is believed that at the birth of the Universe, a whirlwind of matter and antimatter, of quarks and exotic leptons, briefly appeared and merged into a sea of energy. The new phenomena and new states of matter in the Universe revealed the deep connection between quarks and the Cosmos. Motivated by these themes, this book discusses different topics: gravitational waves, dark matter, dark energy, exotic contents of compact stars, high-energy and gamma-ray astrophysics, heavy ion collisions and the formation of the quark - gluon plasma in the early Universe. The book presents some of the latest researches on these fascinating themes and is useful for experts and students in the field.

There are reasons to believe the 21st century will be the best ever for astrophysics: the James Webb Space Telescope will extend nearly twenty times the present observational limit of visible light; neutrino massiveness opens a new window for exploration on dark energy and dark matter physics and is expected to provide insights into the fate of the Universe; the Higgs boson may allow for an understanding of the weakness of gravity; gravitational waves produced at the birth of the Universe and by compact stellar objects (supermassive black holes, black hole/neutron star mergers, gamma-ray bursts, white dwarf inspirals) have unveiled a new area of astronomy. Against this background, compact stars, the theme of this volume, present unique astrophysical laboratories for probing the fabric of space-time and the building blocks of matter and their interactions at physical regimes not attainable in terrestrial laboratories.

2015 is a milestone year for the history of science: It marks the 100th anniversary of the presentation of the Theory of General Relativity by Albert Einstein, in its final formulation, to the Royal Prussian Academy of Sciences.
