A massive galaxy supercluster in the early universe

The structure of the universe is often described as being a cosmic web of filaments, nodes, and voids, with the nodes being clusters of galaxies, the largest gravitationally bound objects known. These nodes are thought to ...

Controlling the waveform of ultrashort infrared pulses

An international team of laser physicists of the attoworld team at LMU and the Max Planck Institute of Quantum Optics has achieved unprecedented control over light pulses in the mid-infrared wavelength range.

Astronomy team finds evidence of galactic metal shrouded in dust

A thorough understanding of galaxy evolution depends in part on an accurate measurement of the abundance of metals in the intergalactic medium—the space between stars—but dust can impede observations in optical wavelengths. ...
