The cosmic microwave background, or CMB, is the electromagnetic echo of the Big Bang, radiation that has been traveling through space and time since the very first atoms were born 380,000 years after our universe began. Mapping ...
Astronomers from Switzerland and Germany have performed multiwavelength observations of a high-synchrotron-peaked blazar known as Mrk 421. Results of this observational campaign provide more insights into the variability ...
In the early morning of Jan. 20 (Beijing Time), the Gravitational Wave High-Energy Electromagnetic Counterpart All-sky Monitor (GECAM or Huairou-1) team reported their first detection of a gamma-ray transient (GRB 210119A) ...
Before researchers can smash together beams of particles to study high-energy particle interactions, they need to create those beams in particle accelerators. And the tighter the particles are packed in the beams, the better ...
Free electron X-ray lasers deliver intense, ultrashort pulses of X-rays, which can be used to image nanometer-scale objects in a single shot. When the X-ray wavelength is tuned to an electronic resonance, magnetization patterns ...
From common soot to precious diamonds, carbon is familiar in many guises, but there have been little more than glimpses of carbon in the liquid form. Researchers at the FERMI Free Electron Laser (FEL) source have now not ...
Using various space observatories, astronomers have conducted multi-wavelength study of a high-magnetic-field pulsar known as PSR J1119−6127, which underwent an outburst in 2016. The results shed more light on the properties ...
Black holes are at the center of almost all galaxies that have been studied so far. They have an unimaginably large mass and therefore attract matter, gas and even light. But they can also emit matter in the form of plasma ...
Giant elliptical galaxies, the oldest known large galactic structures in the universe, have no spiral arms and little or no current star formation activity, but their central supermassive black holes are often active galactic ...
A new method uses swirls of light to enable researchers to observe previously invisible quantum states of electrons. The method was developed by physicists from Martin Luther University Halle-Wittenberg (MLU) and an international ...
