Earth's atmosphere is an impediment to astronomical observations. Not only is cloudy weather a problem, but temperature fluctuations in the atmosphere mean that ground-based telescopes require ...

Assistant Professor Haocun Yu is something of a scientific diplomat. In a recent Physical Review Letters publication, she and ...

Purdue faculty dedicate countless hours to exploring the frontiers of their respective fields, pushing the boundaries of knowledge and contributing to the ever-evolving landscape of academia. To ...

The ESO (European Southern Observatory) has announced the successful observation of an exoplanet using optical interferometry. It's the first time an exoplanet has been "seen" in this manner and the ...

Large-scale atom interferometers, analogous to optical interferometers but measuring the difference in phase between atomic matter waves on different paths, are intended to be key elements in future ...

The successful creation of a guide star above the European Southern Observatory (ESO) Paranal site in Chile with freshly installed lasers marks a new era of interferometry, according to the ESO team.

The researchers fabricated chip-based interferometers (pictured) to measure how light propagating through a magneto-optic material changed in response to a magnetic field. WASHINGTON — Researchers ...

An illustration of the Berkeley group’s lattice interferometer, where the standing wave of a laser beam in a cavity suspends each atom in a spatially separated quantum superposition state, in the ...
