Galaxy Bulges and Elliptical Galaxies (PDF 16P)
Our knowledge on the central components of disk galaxies has grown substantially in the past few decades, particularly so in the last. This frantic activity and the complexity of the subject promote confusion in the community. In these notes the author discuss the concept of galactic bulge and its different flavors. This also address fundamental scaling relations and the bulge-elliptical galaxy connection, their central black holes and formation models. In particular, this book aims at conveying three important notions: box peanuts are just the inner parts of bars; the physical reality of two different families of bulges is evident and at the high mass end, at least, classical bulges are not just scaled down ellipticals surrounded by disks.

Astronomy is the scientific study of the universe as a whole, and of celestial bodies and the underlying physics governing those bodies. This Wikibook introduces the reader to that tapestry and the process that revealed it to humanity. It presents astronomy not only as a field of knowledge, but also as a human endeavor in science.

The Elements of Astronomy, Or, The World as it Is, and as it Appears
As such a book, The Elements of Astronomy, or the World as it is, and as it appears, is offered by a teacher to the teaching and studying public. Had the writer aimed only to excite an interest in the subject, it would have been shorter and more attractive , but it is intended, likewise, to exercise the student's memory, reason, and imagination.
