Origin of the peculiar eccentricity distribution of the inner cold Kuiper belt
A. Morbidelli, H. S. Gaspar, D. Nesvorny
Dawson and Murray-Clay (2012) pointed out that the inner part of the cold population in the Kuiper belt (that with semi major axis a<43.5 AU) has orbital eccentricities significant…
Terrestrial Planet Formation in a protoplanetary disk with a local mass depletion: A successful scenario for the formation of Mars
A. Izidoro, N. Haghighipour, O. C. Winter +1
Models of terrestrial planet formation for our solar system have been successful in producing planets with masses and orbits similar to those of Venus and Earth. However, these mod…
Inflationary Steps in the Planck Data
V Miranda, Wayne Hu
We extend and improve the modeling and analysis of large-amplitude, sharp inflationary steps for second order corrections required by the precision of the Planck CMB power spectrum…
Shape Primitive Histogram: A Novel Low-Level Face Representation for Face Recognition
Sheng Huang, Dan Yang, Haopeng Zhang +2
We further exploit the representational power of Haar wavelet and present a novel low-level face representation named Shape Primitives Histogram (SPH) for face recognition. Since h…
Face Recognition via Globality-Locality Preserving Projections
Sheng Huang, Dan Yang, Fei Yang +3
We present an improved Locality Preserving Projections (LPP) method, named Gloablity-Locality Preserving Projections (GLPP), to preserve both the global and local geometric structu…
Why robots? A survey on the roles and benefits of social robots in the therapy of children with autism
John-John Cabibihan, Hifza Javed, Marcelo Ang +1
This paper reviews the use of socially interactive robots to assist in the therapy of children with autism. The extent to which the robots were successful in helping the children i…
Deformations of large N=(4,4) 2D SCFT from 3D gauged supergravity
Parinya Karndumri
Supersymmetric and non-supersymmetric deformations of large SCFT with superconformal symmetry are explored in the gravity dual described by…
Covariant Bardeen Perturbation Formalism
S. D. P. Vitenti, F. T. Falciano, N. Pinto-Neto
In a previous work we obtained a set of necessary conditions for the linear approximation in cosmology. Here we discuss the relations of this approach with the so called covariant…
First Measurement of the Cross-Correlation of CMB Lensing and Galaxy Lensing
Nick Hand, Alexie Leauthaud, Sudeep Das +33
We measure the cross-correlation of cosmic microwave background lensing convergence maps derived from Atacama Cosmology Telescope data with galaxy lensing convergence maps as measu…
On detecting interactions in the dark sector with H(z) data
Pedro C. Ferreira, Diego Pavón, Joel C. Carvalho
An interesting approach to the cosmological coincidence problem is to allow dark matter and dark energy interact with each other also nongravitationally. We consider two general An…
Anisotropic q-Gaussian velocity distributions in LambdaCDM halos
Leandro J. Beraldo e Silva, Gary A. Mamon, Manuel Duarte +3
The velocity distribution function (VDF) of dark matter (DM) halos in CDM dissipationless cosmological simulations, which must be non-separable in its radial and tangential comp…
Generalized quasi-dilaton theory
Antonio De Felice, A. Emir Gumrukcuoglu, Shinji Mukohyama
Recently the first example of a unitary theory of Lorentz-invariant massive gravity allowing for stable self-accelerating de Sitter solutions was found, extending the quasidilaton…
Scalar perturbations in a Friedmann-like metric with non-null Weyl tensor
Grasiele B. Santos, Eduardo Bittencourt, José M. Salim
In a previous work the authors have solved the Einstein equations of General Relativity for a class of metrics with constant spatial curvature, where it was found a non vanishing W…
Quintessential power-law cosmology: dark energy equation of state
Burin Gumjudpai
Power-law cosmology with scale factor as power of cosmic time, $a \propto t^{\a}$, is investigated. We review and discuss value of $\a$ obtained from various types of observation.…
1/2-BPS Domain wall from N=10 three dimensional gauged supergravity
Parinya Karndumri
We explicitly construct Chern-Simons gaged supergravity in three dimensions with non-semisimple gauge group . The gauge group is embedded in $E…
Composite Inflation confronts BICEP2 and PLANCK
Phongpichit Channuie, Khamphee Karwan
We examine observational constraints on single-field inflation in which the inflaton is a composite field stemming from a four-dimensional strongly interacting field theory. We con…
3D Supergravity from wrapped D3-branes
Parinya Karndumri, Eoin O Colgain
AdS_3 solutions dual to N = (0,2) SCFTs arise when D3-branes wrap Kahler two-cycles in manifolds with SU(4) holonomy. Here we review known AdS_3 solutions and identify the correspo…
Towards consistent extension of quasidilaton massive gravity
Antonio De Felice, Shinji Mukohyama
We present the first example of a unitary theory of Lorentz-invariant massive gravity, with all degrees of freedom propagating on a strictly homogeneous and isotropic, self-acceler…
Planck constraints on single-field inflation
Shinji Tsujikawa, Junko Ohashi, Sachiko Kuroyanagi +1
We place observational constraints on slow-variation single-field inflationary models by carrying out the cosmological Monte Carlo simulation with the recent data of Planck combine…
Possible existence of viable models of bi-gravity with detectable graviton oscillations by gravitational wave detectors
Antonio De Felice, Takashi Nakamura, Takahiro Tanaka
We discuss graviton oscillations based on the ghost free bi-gravity theory. We point out that this theory possesses a natural cosmological background solution which is very close t…
