One of the most rapidly evolving elements of astronomy research is how we handle data. A new Special Issue of ApJ Supplements looks at related challenges and resources.

black holes in a globular cluster

Can black holes of any mass exist, or are there gaps in their possible sizes? Mergers may play a large role in the answer to this question.
