In a strange twist of science, astronomers using the Herschel Space Observatory have discovered that a suspected ring at the center of our galaxy is warped for reasons they cannot explain. ... New observations from the Herschel Space Observatory show a bizarre, twisted ring of dense gas at the center of our Milky Way Galaxy. ...
Configuration Files | ... Options | ... This version of Apache includes changes allowing it to run on IBM's EBCDIC-based TPF (Transaction Processing Facility) operating system. ... It is passed to Apache through the ZINET XPARM field since ZINET is the only way to start the server on TPF. A third group of options apply to both the informational displays (ZFILE) and running the server (ZINET XPARM): -d, -D and -f. The rest of Apache's options are either not applicable or are not supported on TPF. ...
... Fractals and multifractals are used to model hierarchical, inhomogeneous structures in several areas of astrophysics, notably the distribution of matter at various scales in the universe. ... It is pointed out that some of the difficulties regarding the convergence rates of algorithms used to determine scaling exponents for a fractal or multifractal, are intrinsically related to its texture, in particular, to its lacunarity . ... Structures with fractal characteristics are important for astrophysics...

... What's a Population . ... It varies, ecologists use the word "population" in several ways; typically a "somewhat isolated collection of individuals." ... There are two "basic models" of population growth. Exponential growth, and logistic growth. ... In logistic growth there are "density-dependent" changes in growth rate that REGULATE population growth. ... The exponential and logistic models treat all individuals in a population the same; but we know that baby's don't reproduce but adults do! ...
... Sizes of spectra The number of spectra that are `spoiled' by overlaps depends on the contrast ratio reached by the MEMS device, the area on the sky covered by an individual spectrum and on the number density of potential spoilers at a given magnitude. ... 4-- NIRSpec contrast and confusion limits 1 low resolution 0.8 0.6 0.4 0.2 0 1 hi resolution 0.8 0.6 0.4 0.2 0 20 Figure 3: Probability that spectra are contaminated at the Galactic pole as a function of the magnitude of the target galaxy. ...
