Keywords: Multiresolution analysis, wavelet, image processing, image restoration, deconvolution . This paper shows how an effective noise suppression strategy can be incorporated into algorithms for the solution of the inverse problem. The residual in the fit of the restored image, at each iteration, is analyzed using a wavelet transform. In order to suppress noise, only significant wavelet coefficients are retained. ...

Smithsonian Astrophysical Observatory Memorandum To : From Date: Re: M. Cappi, Strong Gravity SDT/YB Team, XMS team : M. Garcia April 14, 2010 XMS high/mid/low resolution event rates for bright AGN mrg-2010-02v2 This memo arises out of the concern that the bright AGN that will be used to observed strong gravity effects ­ in particular those for which time-resolved measurements of test particle orbits will be made ­ may generate counting rates in the XMS that are sufficient to overwhelm it. ...

Solar High Resolution Studies . ... Dynamic magnetic fields continuously emerging from the solar interior on a wide range of scales, and their interaction with convectively-driven plasma flows, play a major role in shaping the whole solar atmosphere. Even though the fundamental spatial scales of turbulence and magnetic fields are still unreachable with present-day telescopes, polarimetric observations at the highest possible resolution will allow important insights into these issues. ...
