In a survey with results presented as a LISA VI conference poster \cite{2010ASPC..433..116I} the question was asked whether the effect of institutional mergers could be evaluated using bibliometric methods. Before 2010, two Finnish astronomical institutes had underwent recent institutional rearrangements, and these could be detected in their publication track records as giving some boost to their evaluation results.
In 2010, University of Helsinki astronomy research underwent similar changes. For analyzing the effect of these, citation counts for Finnish astronomy papers were retrieved from Web of Science. Figure 5 shows the number of citations by year. Results for both University of Helsinki and Aalto University (formerly Helsinki University of Technology) show a sharp growth curve starting from 2010. One is tempted to interpret this as proof for the success of institutional changes. However, the reasons could be complex, as bibliometrics seldom gives straight answers. Both universities have been active participants in the Planck collaboration and this could explain some of the growth, but not all of it.
Another indication is the upward turn in the cited references in Figure 3. Helsinki astronomers seem successful and productive, with access to the resources they need for doing their research.
