We present Atacama Large Millimeter/submillimeter Array measurements of the “Cosmic Seagull,” a strongly magnified galaxy at z = 2.7779 behind the Bullet Cluster. We report CO(3–2) and continuum 344 μm (rest-frame) data at one of the highest differential magnifications ever recorded at submillimeter wavelengths (μ up to ∼50), facilitating a characterization of the kinematics of a rotational curve in great detail (at ∼620 pc resolution in the source plane). We find no evidence for a decreasing…

Intense star formation within resolved compact regions in a galaxy at z = 2.3

TLDR
Observations of the sub-millimetre galaxy SMMJ2135-0102, which has been gravitationally magnified by a factor of 32 by a massive foreground galaxy cluster lens, find that the luminosity densities of these star-forming regions are comparable to the dense cores of giant molecular clouds in the local Universe, but they are about a hundred times larger and 107 times more luminous.
