Авторский коллектив из группы астрономов и исследователей рассказывает про книги об огромном ансамбле звезд, газа и пыли, объединенных в темных материальных оболочках. Они являются основными элементами Вселенной, собранными в группы, кластеры и сверхкластеры. Эти галактики существуют в различных формах - либо в виде сфероидов или дисков. Классификация, такие как последовательность Хаббла (основанная на концентрации массы и доли газа) и цветовая характеристика (которая разделяет голубую и красную полосы
The book talks about the size, shape, and constitution of galaxies. Despite a total lack of similarity with the book you're looking for (that's not a popular subject), I might point out that it does talk at length about thousands ofGCCs, galaxies of large galaxies, and the evolution of those.

Описание книги от Группа авторов
Galaxies are vast ensembles of stars, gas and dust, embedded in dark matter halos. They are the basic building blocks of the Universe, gathered in groups, clusters and super-clusters. They exist in many forms, either as spheroids or disks. Classifications, such as the Hubble sequence (based on mass concentration and gas fraction) and the colormagnitude diagram (which separates a blue cloud from a red sequence) help to understand their formation and evolution. Galaxies spend a large part of their lives in the blue cloud, forming stars as spiral or dwarf galaxies. Then, via a mechanism that is still unclear, they stop forming stars and quietly end in the red sequence, as spheroids. This transformation may be due to galaxy interactions, or because of the feedback of active nuclei, through the energy released by their central super-massive black holes. These mechanisms could explain the history of cosmic star formation, the rate of which was far greater in the first half of the Universe's life. <p><i>Galaxies</i> delves into all of these surrounding subjects in six chapters written by dedicated, specialist astronomers and researchers in the field, from their numerical simulations to their evolutions.
