Astronomers led by the University of Colorado and Carnegie Observatories have shown that a miniature galaxy less than one-hundredth the size of the Milky Way is ejecting large quantities of gas and energy into huge regions of intergalactic space.
“This discovery suggests tiny galaxies that appear very faint and dormant today were once much brighter and more active,” said CU-Boulder graduate student Brian Keeney. “It also indicates similar galaxy systems may have been primarily responsible for the chemical evolution of the universe in the very early stages of galaxy evolution,” said Keeney, who presented the results of the research at the American Astronomical Society Meeting held in Nashville, Tenn., May 25 through May 29.
CU-Boulder teamed up with the Carnegie Institution in Washington, D.C., and East Tennessee State University using the Hubble Space Telescope and ground-based telescopes to make a series of observations. Ray Weymann of the Carnegie Institution led a team that used the electromagnetic spectrum from the brightest quasar in the sky, 3C273, to discover a dense cloud of gas in the far reaches of intergalactic space.

Whispering gallery mode (WGM) resonators are used to make tiny micro-lasers, sensors, switches, routers and other devices. These tiny structures rely on a...
Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
