Pattern

regexengine-agnostic

@([A-Za-z0-9_]{1,15})\b   (flags: g)

Raw source: @([A-Za-z0-9_]{1,15})\b

How it works

@ matches the literal at-sign. The capturing group ([A-Za-z0-9_]{1,15}) captures 1–15 characters of the Twitter username alphabet. \b prevents partial matches inside longer words.
