Physical Association and Periodicity in Quasar Families |
We
have used a custom computer program to test for physical
association of quasars with parent galaxies and for
periodicity in quasar redshifts. We examine every object
catalogued in the 2dF deep survey strips. Around each
galaxy quasars are detected as physically associated
with a putative parent galaxy if their redshifts conform
to derived constraints. |

Quasar Additional Intrinsic Redshift
Mechanism? |
From observations and spectral
peculiarities, Quasars have variable "intrinsic"
redshift(s) added to Hubble redshift. Two Quasar
redshift anomalies are examined which may originate from
photon-Raman energy-loss interactions with surrounding
variable cloud.
(1) H:21 cm redshift is small
compared to larger redshift of higher energy photons.
(2) The hydrogen Balmer lines show an additionally
redshifted broadened component. |

Search for time dilation in quasar light curves |
This paper describes a search for time dilation in
quasar light curves using Fourier power spectrum
analysis. The
results appear to show that time dilation is not present
in the characteristic timescale of variation of the
quasars. Possible
explanations for this are discussed. |
