I recently read an article that said our Milky Way Galaxy can be
subdivided into four sections: halo, bulge, thick disk, and thin
disk. However the article wasn't clear where the sections are
located. I was particularly confused about where the 'halo' was
located. The article sort of implies it is at the center of the
galaxy but the word (i.e. the meanings associated with 'halos') is
more suggestive of being on the outskirts.

Hot, massive haloes found around most spiral galaxies (Forwarded) ... Astronomers using ESA's XMM-Newton observatory have found very hot gaseous haloes around a multitude of spiral galaxies similar to our Milky Way galaxy.... Galaxy 'haloes' are often seen in so-called 'starburst' galaxies, the locations of concentrated star formation, but the discovery of high-temperature haloes around non-starburst spiral galaxies opens the door to new types of measurements once only dreamed about. ... Like a giant pot of boiling water, the steady activity of star formation over millions and millions of years percolates outward to form the galaxy halo.... (sci.astro)
NASAs Chandra Finds Evidence for Quasar Ignition (Forwarded) ... Scientists using NASA's Chandra X-ray Observatory have detected an extensive halo of hot gas around a quiescent spiral galaxy. ... This discovery is evidence that galaxies like our Milky Way are still accumulating matter from the gradual inflow of intergalactic gas.... "What we are likely witnessing here is the ongoing galaxy formation process," said Kristian Pedersen of the University of Copenhagen, Denmark, and lead author of a report on the discovery. ... Chandra observations show that the hot halo extends more than 60,000 light years on either side of the disk of the galaxy known as 4C37.43. ... (sci.astro)
