The phrase "augment resolution" is correct and usable in written English.
It can be used in contexts related to improving the clarity or detail of an image, video, or data set.
Example: "To enhance the quality of the image, we need to augment resolution before printing."
Alternatives: "enhance clarity" or "improve detail".
Given a merger tree extracted from an N-body simulation, our goal is to augment the resolution of the tree by grafting on higher resolution branches which match the pre-existing tree structure to some given precision.
We demonstrate a method to augment the resolution of N-body merger trees by grafting in branches of Monte Carlo merger trees with higher resolution, but which are consistent with the pre-existing branches in the N-body tree.
We have described a simple yet powerful way to augment the resolution of merger trees extracted from N-body simulations of structure formation by grafting in high resolution branches generated using the PCH algorithm.
In Section 2 we describe our method for augmenting the resolution of N-body merger trees, and in Section 3 we demonstrate how this approach leads to convergence in galaxy properties (specifically stellar masses are explored in this work, although our approach works for all galaxy properties).
To investigate these possibilities we repeat this study but instead of using trees extracted from the Millennium and Millennium-II simulation we generate a set of PCH trees matched to the resolutions of those two simulations (referring to these as 'pseudo-Millennium' and 'pseudo-Millennium-II' trees) and then attempted to augment the lower resolution trees to match the higher resolution trees.
Trees are pruned as described above, then augmented to a resolution of (2.5times10^{9}{mathrm{M}}_{odot}).
The three green lines indicate results for trees augmented to a resolution of (2.5times10^{9}{mathrm{M}}_{odot}) using our method for three different values of (epsilon_{0}), as indicated in the panel.
Note that we are not interested in whether this relation (which depends on the specific implementation of baryonic physics in our model) agrees well with observations, but merely whether it converges as we augment trees to higher resolution.
When augmented to a mass resolution of (2.5times10^{9}{mathrm{M}}_{odot}) the Millennium trees produce results in good agreement with the 'native' trees.
A 60-mer, 44,000-probe oligonucleotide array with a 50-kb average spatial resolution was augmented with high-density probe tiling at loci that are frequently aberrant in CLL.
