We investigate recent claims for a detection of “Hawking points” (positions on the sky with unusually large temperature gradients between rings) in the cosmic microwave background (CMB) temperature maps at the 99.98 % confidence level. We find that, after marginalization over the size of the rings, an excess is detected in Planck satellite maps at only an 87 % confidence level (i.e., little more than 1 σ). Therefore, we conclude that there is no statistically significant evidence for the… 
Radial derivatives as a test of pre-big bang events on the Planck data
Although the search for azimutal patterns in cosmological surveys is useful to characterise some effects depending exclusively on an angular distance within the standard model, they are considered as

In this contribution, we model the Solar radiant heat as waves obeying the Stefan-Boltzmann law. The Solar radiant heat is reflected on the termination shock (TS) back towards to the Solar System.

We examine if there are grounds to entertain the Penrose suggestion as to black holes from a prior cycle of creation appearing in the present cosmos. There are two cases to consider. One a singular
Conformal Cyclic Evolution of the Universe: a Loop Quantum Gravity Perspective
The conformal cyclic cosmological evolution of the universe is discussed with the principles of loop quantum gravity. The application of quantum mechanical aspects enables connecting surface between
Proposals on Conformal Cyclic Evolution of The Universe
On the conformal cyclic evolution of the universe, two ideas are proposed. With the help of loop quantum gravity, loop quantum cosmology and conformal cyclic cosmology these postulates are proven to

Apparent evidence for Hawking points in the CMB Sky★
This paper presents strong observational evidence of numerous previously unobserved anomalous circular spots, of significantly raised temperature, in the cosmic microwave background sky. The spots

No evidence for anomalously low variance circles on the sky
In a recent paper, Gurzadyan & Penrose claim to have found directions on the sky centred on which are circles of anomalously low variance in the cosmic microwave background (CMB). These features are

In this Letter, we search for concentric circles with low variance in cosmic microwave background sky maps. The detection of such circles would hint at new physics beyond the current cosmological

In a recent analysis of the 7-year WMAP temperature sky maps, Gurzadyan and Penrose claim to find evidence for violent pre-Big Bang activity in the form of concentric low-variance circles at high
More on the low variance circles in CMB sky
Two groups [3,4] have confirmed the results of our paper concerning the actual existence of low variance circles in the cosmic microwave background (CMB) sky. They also point out that the effect does

We present a method for the computation of the variance of cosmic microwave background (CMB) temperature maps on azimuthally symmetric patches using a fast convolution approach. As an example of the

A new analysis of the CMB, using WMAP data, supports earlier indications of non-Gaussian features of concentric circles of low temperature variance. Conformal cyclic cosmology (CCC) predicts such
