This paper describes the invention of distributed feedback (DFB) structures for integrated optics. The realization of complex structures was carried out in acoustics as cascades of Surface Acoustic ...

The large-scale structure of the universe—the gigantic, hierarchical cosmic web of structures bound by gravity—is mostly made up of dark matter. The growth of the large-scale structure, from ...

Earlier this year, the Dark Energy Spectroscopic Instrument (DESI) completed observations that mapped 47 million galaxies across 11 billion light-years, allowing astronomers to better evaluate the ...

Researchers led by the University of Tsukuba present computer simulations that capture the complex dynamics of elusive neutrinos left over from the Big Bang Current simulations of cosmic structure ...

A new JCAP study tests an “emulator” to reconstruct the large-scale structure of the cosmos If you think a galaxy is big, compare it to the size of the Universe: it’s just a tiny dot which, together ...

Velocity streamlines within the reconstructed volume, with colored envelopes associated with the prominent nearby basins of attraction. The map and streamlines have been cropped to the region covered ...

New observations suggest our estimates of the cosmic dipole effect are actually in line with the large scale structure of the universe. When you purchase through links on our site, we may earn an ...

The large-scale structure of the Universe arises from the gravitational amplification of primordial fluctuations, producing a cosmic web of galaxies, filaments, clusters and voids. At sufficiently ...

Mikhail Ivanov, Oliver Philcox, and Marko Simonović won the New Horizons Award for their work on large scale structures — the strands and filaments of our universe which contain buried clues to its ...
