An Anomaly in the Angular Distribution of Quasar Magnitudes: Evidence for a Bubble Universe with a Mass ~10^21 M\odot
Anomaly Angular Distribution Quasar Magnitudes Bubble Universe Mass
2012/2/21
Quasars provide our farthest-reaching view of the Universe. The Sloan Survey now contains over 100,000 quasar candidates. A careful look at the angular distribution of quasar magnitudes shows a surpri...
Orbital effects of the time-dependent component of the Pioneer anomaly
Orbital effects time-dependent component Pioneer anomaly
2011/10/17
We work out the impact that the recently determined time-dependent component of the Pioneer Anomaly (PA), interpreted as an additional exotic acceleration of gravitational origin with respect to the w...
Average Inhomogeneities in Milky Way SNII and The PAMELA Anomaly
PAMELA Anomaly Supernova Remnant
2011/9/29
A model is presented to estimate the fraction of Supernova Type-II events (SNII) occurring inside vs. outside a spiral arm for a given star formation episode. The probability distribution function (PD...
On the rate of gravitational inflaton decay via gauge trace anomaly
gravitational inflaton decay gauge trace anomaly
2010/11/17
We analyze decay processes of the inflaton field, , during the coherent oscillation phase after inflation in f( )R gravity. It is inevitable that the inflaton decays grav-itationally into gauge field...
The radius anomaly in the planet/brown dwarf overlapping mass regime
radius anomaly mass regime
2010/11/9
The recent detection of the transit of very massive substellar companions (Deleuil et al. 2008; Bouchy et al. 2010;Anderson et al. 2010; Bakos et al. 2010) provides a strong con-
straint to planet an...
Conformal Cosmology and the Pioneer Anomaly
Cosmology and Extragalactic Astrophysics (astro-ph.CO) General Relativity and Quantum Cosmology (gr-qc)
2011/1/6
We review the fundamental results of a new cosmological model, based on conformal gravity, and apply them to the analysis of the early data of the Pioneer anomaly. We show that our conformal cosmology...
A Mismatch in the Ultraviolet Spectra between Low-Redshift and Intermediate-Redshift Type Ia Supernovae as a Possible Solution to the U-Band Anomaly
Cosmology and Extragalactic Astrophysics (astro-ph.CO) Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/4
We present Keck high-quality rest-frame ultraviolet (UV) through optical spectra of 21 Type Ia supernovae (SNe Ia) in the redshift range 0.11 < z < 0.37 and a mean redshift of 0.22 that were discovere...
I present an argument, based on the topology of the universe, why there are three generations of fermions. The argument implies a preferred gauge group of SU(5), but with SO(10) representations of the...
Conserved Gravitational Charges, Locality and the Holographic Weyl Anomaly - a Fresh Viewpoint
Gravitational Charges the Holographic Weyl Anomaly asymptotic isometries
2010/10/18
Since the proposal of the AdS/CFT correspondence, made by Maldacena and Witten, there has been some controversy about the definition of conserved Noether charges associated with asymptotic isometries ...
Renormalization Group in Curved Space and the Problem of Conformal Anomaly
Renormalization Group Curved Space Conformal Anomaly
2010/10/18
Renormalization Group (RG) is a powerful method for investigating quantum effects of matter fields on curved background. The formalism of RG in curved space is well known since 1984, but its applicati...
