Video/text Black Holes from Particle Physics Perspective
Description By Georgi Dvali, 2014. We review physics of black holes, both large and small, from a particle physicist's perspective, using particle physics tools for describing concepts such as entropy, temperature and quantum information processing. We also discuss microscopic picture of black hole formation in high energy particle scattering, potentially relevant for high energy accelerator experiments, and some differences and similarities with the signatures of other BSM physics.

Video/text Ultra-High Energy Cosmic Rays
Description By Maria Teresa Dova, 2012. The origin of the highest energy cosmic rays (UHECR) with energies above 1000 TeV, is still unknown. The discovery of their sources will reveal the engines of the most energetic astrophysical accelerators in the universe. In these lectures we present the recent observational results from HiRes, Telescope Array and Pierre Auger Observatory as well as (some of) the possible astrophysical origins of UHECR. ...

Video/text Particle Physics Foundations of Dark Matter, Dark Energy, and Inflation
Description By Edward W. Kolb, 2012. Ninety-five percent of the present mass-energy density of the Universe is dark. Twenty-five percent is in the form of dark matter holding together galaxies and other large scale structures, and 70% is in the form of dark energy driving an accelerated expansion of the universe. Dark matter and dark energy cannot be explained within the standard model of particle physics. ...

Video/text Black Holes in the Cosmos, the Lab, and in Fundamental Physics
Description By Steve Giddings, 2010. Black holes present the extreme limits of physics. They are ubiquitous in the cosmos, and in some extra-dimensional scenarios they could be produced at colliders. They have also yielded a puzzle that challenges the foundations of physics. These talks will begin with an overview of the basics of black hole physics, and then briefly summarize some of the exciting developments with cosmic black holes. ...

Video/text Supernova explosions, black holes and neutron stars
Description By Adam Burrows, 2008. Modern supernova simulations suggest that one or more of three general classes of explosion mechanisms are employed by Nature to end the life of a massive star and to give birth to neutron stars and black holes. ...

Video/text A Dark Universe: Dark Matter and Dark Energy
Description By Edward W. Kolb, 2008. According to the standard cosmological model, 95% of the present mass density of the universe is dark: roughly 70% of the total in the form of dark energy and 25% in the form of dark matter. In a series of four lectures, I will begin by presenting a brief review of cosmology, and then I will review the observational evidence for dark matter and dark energy. ...

Video/text Particle Cosmology
Description By Dominik J. Schwarz, 2007. The understanding of the Universe at the largest and smallest scales traditionally has been the subject of cosmology and particle physics, respectively. Studying the evolution of the Universe connects today's large scales with the tiny scales in the very early Universe and provides the link between the physics of particles and of the cosmos. ...

Video/text Gravitational Waves Astronomy
Description By Michael R. Landry, 2006. In this three-part lecture series, we give an overview of the field, including material on gravitational wave sources, detection methods, some details of interferometric detectors, data analysis methods, and current results from observational data-taking runs of the LIGO and GEO projects. ...

Video/text Exploring Planets and Moons in our Solar System
Description By H. O. Rucker, 2006. The lecture series comprises 5 lectures starting with the interplanetary medium, the solar wind and its interaction with magnetized planets. Knowledge on the magnetically dominated 'spheres' around the Giant Planets have been obtained by the Grand Tour of both Voyager spacecraft to Jupiter, Saturn, with the continuation of Voyager 2 to Uranus, and Neptune, in the late seventies and eighties of last century. ...

Video/text Deep Space Telescopes
Description By G. Bignami, 2006. The short series of seminars will address results and aims of current and future space astrophysics as the cultural framework for the development of deep space telescopes. It will then present such new tools, as they are currently available to, or imagined by, the scientific community, in the context of the science plans of ESA and of all major world space agencies. ...

Video/text Surviving in space: the challenges of a manned mission to Mars
Description By L. Pinsky, 2005. Lectures: 1. Understanding the Space Radiation Environment; 2. Dosimetry and the Effects of the Exposure of Human Tissue to Heavily Ionizing Radiation; 3. Modelling the Interaction of the Space Radiation in Spacecraft & Humans, and Assessing the Risks on a Mission to Mars. ...

Video/text Cosmology for Particle Physicists
Description By S. Carroll, 2005. The past few years have seen dramatic breakthroughs and spectacular and puzzling discoveries in astrophysics and cosmology. We know much about the universe, but understand very little. Open questions include the nature of the dark matter and dark energy, the origin of the matter/antimatter asymmetry, the possibility of inflation, and the role of string theory and extra dimensions in the early universe. ...

Video/text Astronomy from Space
Description By Thierry Courvoisier, 2005. In the very wide field of High Energy astrophysics we will select a number of topics that range from the source of radiative energy in the deep potential well around Schwarzschild and Kerr black holes and the basics of accretion disks around compact objects to the description and (where possible) the understanding of binary systems including a compact object (neutron star or black hole), of Active Galactic Nuclei and of gamma ray bursts. ...

Video/text Search for Dark Matter
Description By B. Sadoulet, 2004. In the first lecture, I will review the most recent cosmological evidence for the pervading dark matter in the universe and the emerging consensus that it is not ordinary matter. ...

Video/text The cosmic microwave background
Description By Mattias Zaldarriaga, 2004. The Cosmic Microwave Background has become an indispensable tool for cosmology. The measurement of its frequency spectrum firmly established the Hot Big Bang model of the Universe. Measurements of anisotropies in its temperature and its degree of polarization provide the earliest snapshot we have of the universe, giving us information about its state at the epoch of hydrogen recombination approximately 300,000 years after the Big Bang. ...

Video Gravitational Waves and Antennas
Description By E. Coccia, 2003. Gravitational waves and their detection represent today a hot topic, which promises to play a central role in astrophysics, cosmology and theoretical physics. Technological developments have enabled the construction of such sensitive detectors that the detection of gravitational radiation and the start of a new astronomy could become a reality during the next few years. ...

Video Introduction to General Relativity and Black Holes
Description By T. Damour, 2003. Physical motivation behind Einstein's theory. Mathematical formalism of General Relativity. Experimental confirmations of Einstein's theory. Introduction to Black Holes physics. ...

Video Escaping in Extra Dimensions
Description By J. D. March-Russell, 2002. Recent progress in the formulation of fundamental theories for a Universe with more than 4 dimensions will be reviewed. Particular emphasis will be given to theories predicting the existence of extra dimensions at distance scales within the reach of current or forthcoming experiments. ...

Video/text Cosmology and the Origin of Structure
Description By E. W. Kolb, 2002. There is now strong evidence that the rich and varied structure we see in the universe today in the form of stars, galaxies, galaxy clusters, and even larger structures, grew from small primordial 'seeds' that were planted in the first second in the history of the universe. Lectures: 1. The observed universe; 2. The growth of cosmological structure; 3. Inflation and the origin of perturbations; 4. Dark matter and dark energy. ...
