Quasars, short for “quasi-stellar radio sources,” are among the most enigmatic and fascinating objects in the cosmos. They are incredibly bright and energetic, emitting radiation across the entire electromagnetic spectrum, from radio waves to X-rays and gamma rays. Quasars are powered by the accretion of material onto supermassive black holes at the centers of galaxies, … Read more
A new telescope called the “Condor Array Telescope” may open up a new world of the very-low-brightness universe for astrophysicists. Four new papers, published back to back in the Monthly Notices of the Royal Astronomical Society (MNRAS) this month, present the first scientific findings based on observations acquired by Condor. The project is a collaborative … Read more
European astronomers recently conducted extensive Very Long Baseline Interferometric (VLBI) observations on the radio jet structure of PKS 2215+020, a powerful quasar. The acquired VLBI data yielded crucial insights into the characteristics of this jet, indicating that PKS 2215+020 exhibits traits typical of a blazar. These findings, unveiled on February 17 in the Universe journal, … Read more
