Twin Quasar: 1979 Lensed into 2 images The lens is a galaxy known as YGKOW G1: First quasar found with a jet with apparent superluminal motion 3C 279: 1971 [25] [26] [27] First quasar found with the classic double radio-lobe structure 3C 47: 1964 First quasar found to be an X-ray source 3C 273: 1967 [39] First "dustless" quasar found
Red quasars are quasars with optical colors that are redder than normal quasars, thought to be the result of moderate levels of dust extinction within the quasar host galaxy. Infrared surveys have demonstrated that red quasars make up a substantial fraction of the total quasar population.
PKS 0438-436, also known as PKS J0440-4333, is a quasar located in constellation Caelum.With a high redshift of 2.86, [1] the object is located 11.2 billion light-years from Earth [2] and is classified as a blazar due to its flat-spectrum radio source, [3] (in terms of the flux density as (F v ~ V-a) with α < 0.5 and its optical polarization.
Quasars, though, are on the small end of the supermassive black hole size class—sometimes just a few days across, or about 1,000 of the distance between Earth and the Sun, Space.com explains ...
ULAS J1120+0641 was discovered by the UKIRT Infrared Deep Sky Survey (UKIDSS), using the UK Infrared Telescope, located in Hawaii. [10] The name of the object is derived from UKIDSS Large Area Survey (ULAS), the name of the survey that discovered the quasar, and the location of the quasar in the sky in terms of right ascension (11h 20m) and declination (+06° 41').

Both images have an apparent magnitude of 17, with the A component having 16.7 and the B component having 16.5. There is a 417 ± 3-day time lag between the two images. [3] The Twin Quasar lies at redshift z = 1.41 (8.7 billion ly), while the lensing galaxy lies at redshift z = 0.355 (3.7 billion ly).
This suggests the quasar is currently undergoing an intense wave of star formations thus increasing its luminosity. [3] A radio jet has also been found on the side of quasar according to a study published in 2023. [5] CCD image of the Cloverleaf quasar taken in March 1988 by the ESO/MPI 2.2m telescope. The four separated images are part of the ...
