Reviewing the fundamental instrumental techniques and current observational results, this book unveils the mysteries of the physical processes in the central parsec of our Milky Way: the super-massive black hole embedded in a central stellar cluster as well as the gas and dust in the circumnuclear region.The observations described cover the entire electromagnetic spectrum from decimeter radio-waves to high energy X-ray and γ-rays, and a comprehensive summary of up-to-date astrophysical interpretations is given.The emphasis is put on observational techniques, image processing aspects, and a detailed presentation of the most cutting-edge work carried out in the near-infrared wavelength regime. These recent results include both the first orbits of stars around the central black hole and the multiwavelength variability of the central source./a

A history of the telescope includes discussion of such related topics as the dark-adapted human eye, interferometry, adaptive optics, and remote sensing.
An exciting introduction to astronomy, the fourth edition of this book uses recent discoveries and stunning photography to inspire non-science majors about the Universe. Written by two highly experienced and engaging instructors, each chapter has been fully updated, with more than 200 new images throughout, including recent images from space missions and the world's best observatories. The newly redesigned text is organized as a series of stories, each presenting the history of the field, the observations made and how they fit within the process of science, our current understanding and what future observations are planned. Math is provided in boxes and easily read around, making the book suitable for courses taking either mathematical or qualitative approaches. New discussion questions encourage students to think widely about astronomy and the role science plays in our everyday lives and podcasts for each chapter aid studying and comprehension.
What is the problem with cosmology? As a science cosmology is limited to the study of the universe as a whole, drawing conclusions based on astronomical observation and mathematical models. Over time cosmology has evolved from a speculative enterprise into a data-driven science; however, even in this new cosmology of facts and figures the origins of our universe remain a mystery, one that will perhaps never be solved. Every day new theories on the birth and evolution of the universe are made without the support of scientific observation-theories that may never be proven by hard evidence. And so cosmology remains a principle driven enterprise, with its roots deeply planted in the soil of unce...
"Hosted by Gemini Observatory during the week of November 3-8 in Hawaii. Called 'The Central 300 Parsecs, ' the conference was sponsored by several observatories on Mauna Kea to stimulate discussions on the galactic core. The conference was held at the Keauhou Beach Resort in Kailua-Kona, on the west side of the Big Island."-
