  Sky distributions of large samples of distant active galactic nuclei (AGNs)
have shown dipoles significantly larger than the cosmic microwave background
(CMB) dipole. However, a recent Bayesian analysis of the QUAIA sample,
comprising 1.3 million quasars, has yielded a dipole that seems to be in tandem
with the CMB dipole, in contravention of most previous studies of AGN dipoles.
Since the question has large cosmological implications, we investigate the
QUAIA quasar sample afresh, by directly computing the dipole from asymmetries
observed in the source number counts. We instead find a dipole 3-4 times as
large as the CMB dipole though in the same direction. Further, it has been
claimed elsewhere that the difference between the CMB dipole and the radio
dipole estimated from the NRAO VLA Sky Survey (NVSS), the first large catalogue
that showed an AGN dipole about four times larger than the CMB dipole, can be
fully accounted for by incorporating the shot-noise and clustering
contributions to the total NVSS dipole. A careful reinvestigation of the NVSS
dipole, however, shows that the random phenomena like shot noise or clustering
cannot account for the actually observed NVSS asymmetries, which show a
systematic dipole pattern over the sky.
