... Meta Index / Home Page / Description The wavelet detection algorithm itself does not use any separate background estimate. ... For the parameter I choose to use a value twice the size of the wavelet scale under investigation (so for every scale a different background map is generated). After one iteration the input for the background estimate is the original image minus the sources, detected at scales smaller or equal to the wavelet scale under investigation. ...

Salinet Points on Dark Matter: Following is an excerpt of an e-mail reply. 1) If inflation is correct then, since luminous stars and galaxies only contribute 0.5% of the closure density, then 99% of the Universe is in the form of dark matter and this, no doubt, must be a particle. ... Neutrinoes are relativistic (e.g. hot dark matter) and therefore they erase fluctuations on small scales (they free stream and fill the horizon in the early universe). ... There is way too much power on large scales. ...
