An international team, including University of Oregon scientists, suggests two possible explanations for the lack of a gravitational wave signal in February's gamma ray burst from Andromeda. The findings propose either a merger event beyond Andromeda or a soft gamma-ray repeater within Andromeda as potential origins.
Researchers from TU Delft have successfully applied seismic interferometry to extract information from seismic noise, which can be used to search for new oil fields. The method has shown promising results in a desert in the Middle East.
Researchers develop atomic interferometers to improve navigation accuracy, testing fundamental laws of physics. The technology could lead to more precise location tracking and better understanding of gravity.
This issue features studies on variability in NGC2301 II, superhumps in cataclysmic binaries, and host galaxies of QSOs at high redshift. Researchers also investigate data exchange standards for optical interferometry and analyze seeing data for the Advanced Technology Solar Telescope.
Researchers at NIST found a significant difference between white light interferometric microscopes and phase shifting interferometers in measuring surface roughness, with discrepancies peaking at 100 nanometers. The study evaluated five instruments from three vendors and compared them to stylus profiling instruments.
Researchers at Georgia Institute of Technology have developed the first storage ring to confine and guide ultra-cold neutral atoms in a circular path. The Nevatron ring marks a step toward creating atom fiber optics that could improve aircraft guidance systems and open new areas of study in basic physics.
Stanford researchers used atom interferometry to measure the force of gravity on individual atoms with unprecedented accuracy. Their findings strengthen the likelihood that previous neutron interferometry experiments were incorrect, validating the power of atom interferometry as a precise measurement tool.
The new gradiometer has the potential to revolutionize submarine navigation and underground structure detection, offering improved accuracy and reduced costs. Its commercial applications include geophysical mineral exploration and archaeological studies, enhancing our understanding of hidden pathways and structures.
Scientists have discovered giant convection cells on the sun, which could play a major role in its rotation and solar activity. These cells are large enough to swallow Jupiter and last for long periods, influencing space weather.
