The timescale of quasar variability is widely expected to show the effects of time dilation. In this Letter, we analyze the Fourier power spectra of a large sample of quasar light curves to look for such an effect. We find that the timescale of quasar variation does not increase with redshift, as required by time dilation. Possible explanations of this result all conflict with widely held consensus in the scientific community.

Quasar Spectral Slope Variability in the Optical Band
We performed a new analysis of B and R light curves of a sample of PG quasars. We confirm the variability-redshift correlation and its explanation in terms of spectral variability, coupled with the
Structure Function Analysis of Long-Term Quasar Variability
In our second paper on long-term quasar variability, we employ a much larger database of quasars than in de Vries, Becker & White. This expanded sample, containing 35,165 quasars from the Sloan
Can microlensing explain the long-term optical variability of quasars?
Although controversial, the scenario of microlensing as the dominant mechanism for the long-term optical variability of quasars does provide a natural explanation for both the statistical symmetry,
Timescale of variation and the size of the accretion disc in active galactic nuclei
This paper sets out to measure the timescale of quasar variability with a view to new understanding of the size of accretion discs in active galactic nuclei. Previous attempts to measure such
Fourier Analysis of Gamma-Ray Burst Light Curves: Searching for a Direct Signature of Cosmological Time Dilation
We study the power density spectrum (PDS) of light curves of the observed gamma-ray bursts (GRBs) to search for a direct signature for cosmological time dilation in the PDS statistics with the GRBs
On Planetary-Mass Compact Objects as Dark Matter
. We assess to what extent the claimed signature of planetary-mass compact objects in the long-term optical light curves of quasars really can be explained by the dark matter populations allowed in
Using quasars as standard clocks for measuring cosmological redshift.
It is shown that one can use quasars as standard clocks, as it is shown by constructing two independent methods of finding the redshift of a quasar from its light curve by fitting the ratio of their redshifts.
AGN variability time scales and the discrete-event model
We analyse the ultraviolet variability time scales in a sample of 15 type 1 Active Galactic Nuclei (AGN) observed by IUE. Using a structure function analysis, we demonstrate the existence in most
Observational evidence favors a static universe
The common attribute of all Big Bang cosmologies is that they are based on the assumption that the universe is expanding. However examination of the evidence for this expansion clearly favors a
Colour changes in quasar light curves
The study of quasar variability has long been seen as a way to understanding the structure of the central engine of active galactic nuclei, and as a means of verifying the morphology of the standard


Quasar Variability and Gravitational Microlensing
In this Letter we examine the claim by Baganoff & Malkan that the timescale of brightness variations of quasars increases with decreasing optical wavelength, and that this effect can offset a time
The variability of optically selected quasars
The variability properties of a sample of 300 optically selected quasars near the South Galactic Pole (SGP) have been studied over a baseline of 16 years using a series of twelve UK Schmidt Telescope
Time Dilation in the Light Curve of the Distant Type Ia Supernova SN 1995K
The light curve of a distant Type Ia supernova acts like a clock that can be used to test the expansion of the universe. SN 1995K, at a spectroscopic redshift of z = 0.479, provides one of the first
Steps toward Determination of the Size and Structure of the Broad-Line Region in Active Galactic Nuclei. XV. Long-Term Optical Monitoring of NGC 5548
We present the results of 3 yr of ground-based observations of the Seyfert 1 galaxy NGC 5548, which, combined with previously reported data, yield optical continuum and broad-line Hβ light curves for
Time Dilation in the Peak-to-Peak Timescales of Gamma-Ray Bursts
We present strong evidence of time stretching in the peak-to-peak timescales in the light curves of BATSE gamma-ray bursts (GRBs). Extensive tests are performed on artificially dilated bursts to
Optical variability in active galactic nuclei: starbursts or disk instabilities?
Aperiodic optical variability is a common property of active galactic nuclei (AGNs), though its physical origin is still open to question. To study the origin of the optical-ultraviolet variability
Time Dilation from Spectral Feature Age Measurements of Type Ia Supernovae
We have developed a quantitative, empirical method for estimating the age of Type Ia supernovae (SNe Ia) from a single spectral epoch. The technique examines the goodness of fit of spectral features
The Late-Time Emission of Thermonuclear Supernovae
A number of questions raised during this meeting can be clarified by the study of the emission of SNe Ia at late times. Do WDs explode below the Chandrasekhar mass? Or, on the contrary, are the
