Excerpt from The Astrophysical Journal, Vol. 31: An International Review of Spectroscopy and Astronomical Physics; January June, 1910 Brooks-swift Of Comet is84'i, of y Cassiopeiae and B Lyme. In the paper on the new star in the Andromeda nebula (astronomische N achrichten, I 12, 390, 1885) he mentions his first experiments on the use Of photography for observations of nebulae, a method he had previously employed for the solar eclipse in 1882. The interesting photograph of a meteor accidentally crossing the field Of his reflector during an exposure on some other Object, and forming a trail like a comet, was made in his earliest photographic researches. His first success in comet photography came in the autumn of 1886, when he Obtained a photograph of Comet 1886 IX. After the Observa tions on the spectrum of U Orionis, he published his first account of his most interesting photographs of nebulae, to which were devoted many years of his assiduous work, and increased a great deal our knowledge of the constitution of the nebulae. The discovery of the small star in the Lyra nebula was considered somewhat doubtful at first by several observers, but was universally recognized as certain after having been thoroughly verified by others. His first photographs showed the great advantage of the new method over visual Observa tions, and on his photographs of comparatively small size von Gothard obtained delicate details which were lacking on the best drawings made with large instruments, or appeared there only as Slight traces. Professor Vogel in Potsdam examined very closely some of von Gothard's photographs, and requested Mr.' S. Widt to make elaborate drawings Of five nebulae, believing that only well-made drawings are able to Show all the fine details Of the originals (astronomische N aohriokten, 119, 337, He emphasizes the fact that small condensations Of the nebulous matter can always be easily distin guished from star-images by examining carefully the silver deposit on the plate. He could make very exact measures of well - marked details on the photographs. The excellence of von Gothard's photographs can also be seen on his photographs Of the small nebula near rda-349980 and of the small nebula, M 57, discovered by Barnard; in this case he succeeded in verifying the existence of these very faint Objects with his comparatively small instrument, though only the Lick telescopes seemed to be large enough to Show them visually (astronomische N aokrichten, 135, II, 1894; Astronomy and Astrophysics, I3, 190.

The telescope carried a plate-holder which could be rotated about a vertical axis so that a considerable part of the spectrum could be brought into focus at one time.

This research monograph presents a new dynamical framework for the study of secular morphological evolution of galaxies along the Hubble sequence. Classical approaches based on Boltzmann’s kinetic equation, as well as on its moment-equation descendants the Euler and Navier-Stokes fluid equations, are inadequate for treating the maintenance and long-term evolution of systems containing self-organized structures such as galactic density-wave modes. A global and synthetic approach, incorporating correlated fluctuations of the constituent particles during a nonequilibrium phase transition, is adopted to supplement the continuum treatment. The cutting-edge research combining analytical, N-body simulational, and observational aspects, as well as the fundamental-physics connections it provides, make this work a valuable reference for researchers and graduate students in astronomy, astrophysics, cosmology, many-body physics, complexity theory, and other related fields.
