Gamma-Ray Bursts as Cosmological Tools

(Submitted on 28 Sep 2009)

Abstract: In recent years there has been considerable activity in using gamma-ray bursts as cosmological probes for determining global cosmological parameters complementing results from type Ia supernovae and other methods. This requires a characteristics of the source to be a standard candle. We show that contrary to earlier indications the accumulated data speak against this possibility. Another method would be to use correlation between a distance dependent and a distance independent variable to measure distance and determine cosmological parameters as is done using Cepheid variables and to some extent Type Ia supernovae. Many papers have dealt with the use of so called Amati relation, first predicted by Lloyd, Petrosian and Mallozzi, or the Ghirlanda relation for this purpose. We have argued that these procedure involve many unjustified assumptions which if not true could invalidate the results. In particular, we point out that many evolutionary effects can affect the final outcome. In particular, we demonstrate that the existing data from Swift and other earlier satellites show that the gamma-ray burst may have undergone luminosity evolution. Similar evolution may be present for other variables such as the peak photon energy of the total radiated energy. Another out come of our analysis is determination of the luminosity function and the comoving rate evolution of gamma-ray bursts which does not seem to agree with the cosmic star formation rate. We caution however, that the above result are preliminary and includes primarily the effect of detection threshold. Other selection effects, perhaps less important than this, are also known to be present and must be accounted for. We intend to address these issues in future publications.

Discovery of a New Dimming Effect Specific to Supernovae and Gamma-Ray Bursts

Authors: Thomas B. Andrews

Because type Ia supernovae (SNs) are anomalously dimmed with respect to the at (qo = 0.5) Friedman Expanding Universe model, I was surprised to find that the brightest cluster galaxies (BCGs) are not anomalously dimmed. Based on the absence of anomalous dimming in BCGs, the following conclusions were reached:

⋅ Since the light from the SNs and BCGs traverses the same space, the current hypothesis of an accelerated expansion of the universe to explain the anomalous dimming of SNs is disproved.
⋅ The cause of the anomalous dimming must be specific to the SNs.

The first conclusion is important since current research in dark energy and the cosmological constant was initiated based on the accelerated expansion hypothesis. The disproof of this hypothesis, therefore, casts serious doubts on the existence of dark energy and the cosmological constant. The second conclusion indicates that the occurrence of anomalous dimming depends on a basic difference between the SNs and BCGs. The only difference besides the obvious – that SNs are exploding stars and the BCGs are galaxies – is that the light curves of the SNs are limited in duration. Due on this difference, I discovered that SNs light curves are broadened at the observer by a new Hubble redshift effect. Since the total energy of the light curve is then spread over a longer time period, the apparent luminosity is reduced at the observer, causing the observed anomalous dimming of SNs. I also show that BCGs are not anomalously dimmed because their absolute luminosity is approximately constant over the time required for the light to reach the observer. The above conclusions also apply to Gamma Ray Bursts (GRBs) since gamma-ray “light” curves are limited in duration. Finally, the light curve broadening effect can be used to determine if the universe is expanding or static. In the expanding universe model, a light curve broadening effect is predicted due to time-dilation for the SNs, GRBs and BCGs. Consequently, if the universe is expanding, two light curve broadening effects should occur for the SNs and GRBs. However, if the universe is static, only one light curve broadening effect will occur for the SNs and GRBs. Fortunately, Golhaber has measured the width’s of SNs light curves and conclusively showed that only one light curve broadening effect occurs. Consequently, the expanding universe model is logically falsified.
