astronomy note introduces you to the wonders of modern astronomy.From the Solar
System to the most distant galaxies, we undertake an eye-opening journey, from
how stars work to the structure of the universe itself.
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.
This book covers the
following topics: What is Radio Astronomy, Early Radio Astronomy, The Radio
Universe, Radiation Fundamentals: Brightness and Flux, Radiative Transfer,
Blackbody Radiation, Larmor's Formula, CMB Radiation, Antenna Fundamentals,
Reflector Antennas, Filled Apertures, Radio Telescopes, Radiometers,
Interferometers, Thermal Emission, Nonthermal Emission, Pulsars and Spectral
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.
This note covers the following topics: general data,
astronomy and astrophysics, radio astronomy, infrared astronomy, ultraviolet
astronomy, xray astronomy, gammaray astronomy, cosmic rays, earths atmosphere
and environment, relativity, atomic physics, electromagnetic radiation, plasma
physics, experimental astronomy and astrophysics, aeronautics and astronautics,
mathematics, statistics, radiation safety and astronomical catalogs.
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.
