I have manually reformatted this article. -- jt]] I wish to report on my latest research shown in ArXiv archive. http://arxiv.org/abs/1307.6589. There are two important points. The first is about the calibration of supernovae type Ia and the second is about publication of results outside the current paradigm. This paper argues that a property of the B14 calibration method for the wi dths of type Ia supernova is that any redshift dependence in the observed widths (or stretch factors) is automatically removed from the calibrated output. The standard calibration method {Guy 2007} uses a light curve template to eliminate the effects of intrinsic wavelength dependent variations from the observed supernova light curves. For example the calibrated light curve width is the observed light curve width divided by a reference width which is the average, weighted by filter gain factors, of the template width over the observed rest-frame (emission frame) wavelengths. The calculation of the reference width mathematically mimics the operation of the telescope observing an ideal supernova. The assumption is that the rest-frame template light curves are the same for all SNe. The virtue of this method is that if there are enough SNe the template light curves can be determined from the observed light curves by averaging them over the rest-frame wavelengths. This averaging is iterated until the reference curves are stable. But if the rest-frame wavelength cover for individual SNe does not cover the full wavelength range this calibration method cannot distinguish between intrinsic wavelength variations in the width and any width dependence on re dshift in the observed widths. Suppose there is redshift dependence that is common to all the SNe then the rest-frame light curve template will include this redshift variation as if it is part of the intrinsic wavelength variation in the light curves. Consequently the calibrated light curves for individual supernovae will not include this redshift dependence. A computer simulation of this calibration process confirmed this conclusion. The standard analysis removes the time dilation factors from the epoch differences before this iterative calibration process is done. Consequently the calibrated light curve widths will, to the first order, be the same whether or not the time dilations are or are not removed. The basic conclusion is that this method of analysis will always produce calibrated widths (stretch factors) that do not show any redshift dependence. The second point is that I have submitted this paper to three journals. In each case they found no problems with the paper but rejected it because it was outside the current paradigm. This is paradigm censorship. I would be interested in any reputable journal that might publish this paper. Regards David Crawford (remove the bird) |
