Redshift z number
WebWhen the velocity of the object is small compared to the speed at which the waves propagate, the magnitude of this blueshift or redshift, called z, is proportional to the shift in wavelength Δλ (see above) over the rest wavelength, λ rest.Furthermore, the magnitude of this blueshift or redshift z is proportional to the object’s velocity v over the velocity at … WebWe present mid- and far-infrared photometry of the high-redshift (z = 4.69) dusty quasar BR 1202−0725. The quasar was detected in the near-infrared, at a flux level (0.7 ± 0.2 mJy) consistent with an average radio-quiet quasar at its redshift. Only upper limits for the emission were obtained in the far-infrared. These upper limits, when combined with data …

Web10. apr 2024 · Using our fiducial models calibrated at z=0, we present predictions for stellar mass functions, rest-frame UV luminosity functions, and various scaling relations. We find that our (dust-free) models predict galaxy number densities at z~11 (z~ 13) that are an order of magnitude (a factor of ~30) lower than the observational estimates. Web7. apr 2024 · In the SDSS DR12Q superset miniJPAS sample, the weighted f1-score reaches 0.87 (0.88) for objects that are mostly within $20 < r \leq 22.5$. Finally, we estimate the number of point-like sources that are quasars, galaxies, and stars in miniJPAS.
