Astronomers have cluster-abell-514.html” title=”Detection of a Massive Curved Radio Jet in Galaxy Cluster Abell 514″>conducted deep low-frequency radio observations of the galaxy cluster Abell 514, using the upgraded Giant Metrewave Radio Telescope (uGMRT). In their results, they detected a large-scale bent radio jet in this cluster. The finding is reported in a paper published October 2 on the pre-print server arXiv.
Galaxy clusters are the largest gravitationally bound structures, consisting of up to thousands of galaxies bound together by gravity. They could be crucial in improving the knowledge about large-scale structure formation and evolution of the universe.
Abell 514 (or A514 for short) is a merging galaxy cluster at a redshift of approximately 0.07, discovered in 1958. It has a mass of about 300 trillion solar masses, overall temperature of 3.8 keV, and its metallicity is estimated to be at a level of 0.22. Previous observations of A514 have found that it has a rich morphology and hosts several extended radio sources.
Recently, a team of astronomers led by Wonki Lee of the Yonsei University in Seoul, South Korea, decided to investigate the radio sources in A514 by performing radio observations of this cluster with uGMRT.
“We observed A514 using uGMRT Band 2 (125−250 MHz), Band 3 (250−500 MHz), and Band 4 (550−850 MHz) with on-source integration times of 3.5, 3.7, and 4.3 hours, respectively,” the researchers explained.
