Maximum Likelihood Cluster Reconstruction
We present a novel method to reconstruct the mass distribution of galaxy clusters from their gravitational lens effect on background galaxies. The method is based on a least-x 2 fit of the two-dimensional gravitational cluster potential. The method combines information from shear and magnification by the cluster lens and is designed to easily incorporate possible additional information. We desc...
متن کاملEntropy-regularized maximum-likelihood cluster mass reconstruction
We present a new method for reconstructing twodimensional mass maps of galaxy clusters from the image distortion of background galaxies. In contrast to most previous approaches, which directly convert locally averaged image ellipticities to mass maps (direct methods), our entropy-regularized maximum-likelihood method is an inverse approach. Albeit somewhat more expensive computationally, our me...

متن کاملEfficient maximum likelihood pedigree reconstruction.
A simple and efficient algorithm is presented for finding a maximum likelihood pedigree using microsatellite (STR) genotype information on a complete sample of related individuals. The computational complexity of the algorithm is at worst (O(n(3)2(n))), where n is the number of individuals. Thus it is possible to exhaustively search the space of all pedigrees of up to thirty individuals for one...
متن کاملmaxAlike: Sequence Reconstruction by Maximum Likelihood Estimation
The task of reconstructing a piece of sequence in a particular species is gaining more and more importance in the light of the rapid development of high-throughput sequencing technologies and their limitations. Applications include not only compensation for missing data in unsequenced genomic regions but also the preparation of customized queries for homology-based searches. Here, we introduce ...
