The Compact Array Broadband Backend (CABB) project has upgraded CSIRO's radio telescope near Narrabri in NSW, increasing its bandwidth from 128 MHz to 2 GHz. This upgrade enables astronomers to capture more data from the sky faster and detect cosmic objects more quickly.
Astronomers have used the world's biggest radio telescope to study the brightest galaxies that NASA's Fermi Gamma-ray Space Telescope can see. The team found a correlation between active galaxies with the brightest gamma-ray emission and those with the fastest jets.
A team of Australian astronomers discovered a puzzling lack of hydrogen gas in distant galaxies, which contradicts expectations based on the Universe's life cycle. The observed absence may be due to the destruction of hydrogen by quasars' intense radiation, leaving behind only ionised particles.
The Lunar Array for Radio Cosmology (LARC) project aims to explore the 'Dark Ages' of the universe when stars and galaxies first formed. The new telescopes will study cosmic background radiation and test current theories about the universe's formation.
The Arecibo Observatory has discovered methanimine and hydrogen cyanide, two key ingredients for life, in a distant galaxy. These molecules were found by searching for radio emission at specific frequencies, using the world's largest and most sensitive radio telescope.
Astronomers can now compete for coordinated observing time on both GLAST and NRAO radio telescopes to study celestial objects in multiple wavelengths. This collaboration enables the study of flares from blazars, a key area of research to understanding supermassive black holes.
The e-MERLIN network will use optical fibers to increase data capacity and sensitivity, enabling UK astronomers to make important contributions to advancing our understanding of the Universe. The new system will allow for detailed radio images of stars and galaxies with unprecedented resolution.
The Arecibo telescope has been made more sensitive with the addition of the ALFA instrument, allowing for faster sky surveys and improved detection of pulsars and other rare celestial phenomena. The new device will also enable astronomers to map the neutral hydrogen gas in our galaxy and others.
The NSF has awarded a design grant for the Square Kilometer Array (SKA) telescope, which aims to be the largest scientific instrument ever built. The U.S. consortium, led by Cornell University, will investigate feed antennas and low-temperature receivers, as well as address radio frequency interference issues.
Scientists have discovered that the May 8 gamma ray burst releases an enormous amount of energy, outshining the sun in its lifetime. Radio observations indicate the fireball expands at nearly the speed of light, with a size estimated to be about one-tenth of a light-year.
