The Feros

The high-octane sequel to The Vindico, for superhero fans everywhere! After using their new superpowers to defeat their evil mentors, James, Hayden, Sam, Emily, and Lana are ready to join the League of Heroes. But as their induction into the League draws near, they are framed by a group of rogue Heroes and given life sentences on the Perch, and the only one who can clear their names is missing. Unsure of who to trust or where to turn, the teens’ new skills are further put to the test when a group of strange Shadow people start trailing their every move and the Vindico, their group of evil mentors, are let out of prison.

X-Men meets The Breakfast Club in this darkly humorous adventure The Vindico are a group of supervillains who have been fighting the League of Heroes for as long as anyone can remember. Realizing they're not as young as they used to be, they devise a plan to kidnap a group of teenagers to take over for them when they retire--after all, how hard can it be to teach a bunch of angsty teens to be evil? Held captive in a remote mansion, five teens train with their mentors and receive superpowers beyond their wildest dreams. Struggling to uncover the motives of the Vindico, the teens have to trust each other to plot their escape. But they quickly learn that the differences between good and evil are not as black and white as they seem, and they are left wondering whose side they should be fighting on after all . . . With fast-paced action, punchy dialogue, and sarcastic humor, this high-stakes adventure from a talented new YA voice pulls you in from the first page.

In the high-octane sequel to "The Vindico, " James, Hayden, Sam, Emily, and Lana are ready to join the League of Heroes. But as their induction draws near, they are framed by a group of rogue Heroes and given life sentences on the Perch.

This is the start of a long process to ultimately operate new advanced capabilities at Paranal that can keep up with the evergrowing need for larger and more complex astrophysical data sets. A modern instrument represents a very significant investment in cash, human resources and time. Such a meeting gives us a precious yardstick to evaluate the competitiveness of 1st-generation instruments and associated current and forthcoming proposals for 1st-generation upgrades. This is also crucial to orient the large research and development effort that will provide the very foundation on which 2nd-generation VLT instrumentation can be built. Finally, it represents a significant step towards defining the hopes and goals for the future Extremely Large Telescope to come. The first outcome of this meeting, already in progress, is outlined in the epilogue.

In order to analyze the light of cosmic objects, particularly at extremely great distances, spectroscopy is the workhorse of astronomy. In the era of very large telescopes, long-term investigations are mainly performed with small professional instruments. Today they can be done using self-designed spectrographs and highly efficient CCD cameras, without the need for large financial investments. This book explains the basic principles of spectroscopy, including the fundamental optical constraints and all mathematical aspects needed to understand the working principles in detail. It covers the complete theoretical and practical design of standard and Echelle spectrographs. Readers are guided through all necessary calculations, enabling them to engage in spectrograph design. The book also examines data acquisition with CCD cameras and fiber optics, as well as the constraints of specific data reduction and possible sources of error. In closing it briefly highlights some main aspects of the research on massive stars and spectropolarimetry as an extension of spectroscopy. The book offers a comprehensive introduction to spectroscopy for students of physics and astronomy, as well as a valuable resource for amateur astronomers interested in learning the principles of spectroscopy and spectrograph design.

Momentous changes swept Spain in the fifteenth century: royal marriage united its two largest kingdoms, the last Muslim emirate fell to Catholic armies, and conquests in the Americas were turning Spain into a great empire. Yet few people could define “Spanishness” concretely. Antonio Feros traces Spain’s evolving ideas of nationhood and ethnicity.

Since the use of high-precision/resolution spectroscopy is closely connected to the ability to collect a large number of photons, the scientific domains using this technique benefit tremendously from the use of 8-meter class telescopes and will fully exploit the tremendous gain provided by future Extremely Large Telescopes (ELTs). This volume comprehensively covers the astrophysical and technical aspects of high-precision spectroscopy with an outlook to future developments.
