Phys.org / JWST spots two early black holes growing far faster than their galaxies
Astronomers have discovered two early-universe galaxies where the central black holes appear to have grown far faster than their host galaxies. Observations with the James Webb Space Telescope (JWST) reveal that the black ...
Phys.org / Astronomers uncover over 1,000 radio galaxies with 'wings,' expanding a rare cosmic class
Astronomers recently carried out a comprehensive search for strange "winged" radio galaxies using data from the LOFAR Two-meter Sky Survey Data Release 2 (LoTSS DR2) and discovered over 1,000 new systems. The paper outlining ...
Science X / What are dark galaxies? Astronomers expose 70 hidden candidates with no visible stars
Galaxies are not always teeming with vibrant, hot young stars. Sometimes, they are rich in gas and dark matter but have very few or no stars, making them extremely difficult to detect. They are called "dark galaxies" and ...
Phys.org / Two blazing quasars caught waltzing into a merger
Astronomers, using the Atacama Large Millimeter/submillimeter Array (ALMA), have confirmed the existence of a close quasar pair housed in a pair of merging galaxies seen when the universe was less than a billion years old, ...
Phys.org / These blazing blue explosions may be born when a compact dead star slams into a Wolf-Rayet star
Luminous fast blue optical transients (LFBOTs) are among the universe's brightest and fastest explosions but their origin is not completely understood. A new study takes a closer look at the galaxies they occur in, offering ...
Phys.org / Astronomers find evidence for three subpopulations of merging black holes
Astronomers analyzing gravitational-wave data from the LIGO-Virgo-KAGRA Collaboration have reported that merging binary black holes fall into three distinct categories. The study shows that the three subpopulations have their ...
Phys.org / A rare 'triple-double' radio galaxy discovered using MeerKAT
Astronomers have discovered an exceptionally rare radio galaxy that has three distinct pairs of radio lobes. This system falls into a subpopulation of radio galaxies known as "triple-double" radio galaxies (TDRGs). Located ...
