Radio-frequency Studies of Galactic Structure,short wavelengths (. = 14.6 m) he observed that part of this noise came preferentially from a certain azimuth. From the variation of this azimuth with the time of the day, and with the time of the year, he concluded that the source was related to the nuclear region of the Galactic System.ironic 发表于 2025-3-25 14:28:05
Classification and Morphology of External Galaxies,e . form of some nebulae was first detected visually by Lord Rosse and his assistants between 1845 and 1850. and the appellation . first used in a purely descriptive way was applied to non-spiral tub presumably external stellar systems by . in 1852..Preserve 发表于 2025-3-25 17:17:59
Large Scale Organization of the Distribution of Galaxies,hese ideas is that the galaxies are clustered, and the other is that the large-scale organization of the distribution of galaxies is statistically uniform. Occasionally, the possibility of higher order clustering of galaxies is also mentioned.rods366 发表于 2025-3-25 23:48:04

Robert L. Koch,Tederson L. Galvanhigh intensity which are described by the term .. At the present time our knowledge of the nature of these sources is very limited and the description . is correspondingly vague. No attempt will be made here to define precisely what is classed as a discrete source, except to state that the term has
