Abstract

The system as a whole is slightly brighter than L relative to the z ∼ 3 Lyman break population, and the total star formation rate inferred from the UV continuum is ≈22 h M ☉ yr -1 ( q 0 = 0.5) assuming the absence of dust extinction. The two individual galaxies are quite small (size scales ≲1 h kpc). Thus these galaxies superficially resemble the "building blocks" of Pascarelle and coworkers; if they comprise a gravitationally bound system, the pair will likely merge in a timescale ∼100 Myr.
