We report results from Chandraobservations of the X-ray jet of 3C 273 during the calibration phase in 2000 January. The zeroeth-order images and spectra from two 40-ks exposures with …

2022年11月19日 · The Air Force posted that bio in March 2021. Since that time, I have been unable to find any additional information on the YF-220 "classified prototype" or X-273 "X …

Harris & Stern (1987) used the Einstein Observatory data on 3C 273 to detect X-ray emission from the jet, which was less than 1% of the flux of the core. More recently, Röser et al. (2000) …

findings from the search for narrow emission lines in the X-ray spectrum of the jet in the AGN 3C 273, and explain why the search for a more complete understanding of Active Galactic Nuclei …

We present images from four Chandra observations of the quasar 3C 273. The zeroth order images from two grating observations using the AXAF CCD Imaging Spectrometer (ACIS-S) …

We present images from five observations of the quasar 3C 273 with theChandra X-Ray Observatory. The jet has at least four distinct features that are not resolved in previous …

2025年3月12日 · We aim to investigate the disc-jet scenario in 3C 273 using broad-band (0.3–78 keV) X-ray spectra from XMM-Newton and NuSTAR. Methods. We used simultaneous XMM …

X-ray emission associated with the jet in 3C 273 The Einstein Observatory exposure of 3C 273 obtained with the High Resolution Imager has been re-analyzed using a subtraction technique. …

The X-ray internal structure of extragalactic jets is analyzed. The Lucy-Richardson deconvolution algorithm is used to restore the image of X-ray sources. The analysis was done for Chandra …

2002年1月1日 · The radio-optical-X-ray spectral energy distributions suggest a common origin for the UV excess and the X-rays from the jet. We discuss how to constrain the emission …
