3C 273 is a quasar located at the center of a giant elliptical galaxy in the constellation of Virgo. It was the first quasar ever to be identified and is the visually brightest quasar in the sky as seen …

2002年10月1日 · Analysis with the discrete correlation function (DCF) method indicates that the variability between any two infrared bands is correlated without any time lag.

2023年4月17日 · This image from Hubble’s Wide Field and Planetary Camera 2 (WFPC2) is likely the best of ancient and brilliant quasar 3C 273, which resides in a giant elliptical galaxy in the …

2024年12月5日 · A Hubble Space Telescope image of the core of quasar 3C 273. A coronagraph on Hubble blocks out the glare coming from the supermassive black hole at the heart of the …

Using the Berkeley spectrometer of the ORFEUS-SPAS II mission, we observed the spectrum of the bright, low-redshift QSO 3C 273 in the wavelength range 900 1200 Å (780 1040 Å in the …

The near-infrared data of the quasar 3C273 are collected from available literature and are used to analyze its variability properties. The largest amplitudes of variations are ΔJ = 1.0, ΔH = 0.9, …

The first quasar identified and the brightest in apparent magnitude, 3C 273 is unusually luminous for being so nearby, and has by far the brightest optical jet known among quasars.

The quasar 3C 273 is a point source around magnitude 12.7 in the constellation Virgo (J2000 RA:12 29 06.7, Dec:+02 03 08.6), and AAVSO charts are available here. AAVSO observer …

2020年8月25日 · 3C 273 was 1.5 billion light years away from the sun, and was receding even further at a rate of 47,000 kilometers per SECOND. This odd object was further away and …

We review the observed properties of the bright quasar 3C 273 and discuss the implications of these observations for the emission processes and in view of gaining a more global …
