14 de may. de 2024 · cosmic microwave background (CMB), electromagnetic radiation filling the universe that is a residual effect of the big bang 13.8 billion years ago. Because the expanding universe has cooled since this primordial explosion, the background radiation is in the microwave region of the electromagnetic spectrum.
Hace 2 días · The cosmic microwave background (CMB or CMBR) is microwave radiation that fills all space in the observable universe. It is a remnant that provides an important source of data on the primordial universe. [1]
Hace 1 día · Contemporary cosmic microwave background (CMB) experiments typically have observing bands covering the range 20 - 800 GHz. Certain science goals, including the detection of $μ$-type distortions to the CMB spectrum and the characterization of low-frequency foregrounds, benefit from extended low-frequency coverage, but the standard CMB detector technology is not trivially adaptable to radio ...
Hace 5 días · As it studies cosmic microwaves, the Simons Observatory in Chile aims to help prove or disprove cosmic inflation, a notion that the universe expanded rapidly in the moment after the Big Bang.
Hace 4 días · Radio JOVE students and amateur scientists from around the world observe and analyze natural radio emissions of Jupiter, the Sun, and our galaxy using their own easy to construct radio telescopes.
14 de may. de 2024 · Astrophysicists have discovered large magnetic toroids in the Milky Way's halo, which impact cosmic ray propagation and the physics of interstellar space. Their research, based on extensive Faraday rotation data, reveals that these toroids extend across the galaxy, confirming the presence of signifi
Hace 5 días · This window shows us the microwave energy known as the cosmic background radiation. It is the "noise" left from shortly after the Big Bang that began the universe billions of years ago.
