A multi-wavelength study of the gravitational lens COSMOS J095930+023427
Shuo Cao, Giovanni Covone, Maurizio Paolillo +1
We present a multi-wavelength study of the gravitational lens COSMOS J095930+023427 (z=0.89), together with the associated galaxy group located at along the line of sigh…
Unifying static analysis of gravitational structures with a scale-dependent scalar field gravity as an alternative to dark matter
David F. Mota, Vincenzo Salzano, Salvatore Capozziello +1
Aims. We investigated the gravitational effects of a scalar field within scalar-tensor gravity as an alternative to dark matter. Motivated by chameleon, symmetron and f(R)-gravity…
Characterising galaxy groups: spectroscopic observations of the Shakhbazyan sample
Diego Capozzi, Marilena Spavone, Silvio Barbati +3
Groups of galaxies are the most common cosmic structures. However, due to the poor statistics, projection effects and the lack of accurate distances, our understanding of their dyn…
The evolution of the mass-size relation for early type galaxies from z~1 to the present: dependence on environment, mass-range and detailed morphology
Marc Huertas-Company, Simona Mei, Francesco Shankar +7
[abridged] We study the dependence of the galaxy size evolution on morphology, stellar mass and large scale environment for a sample of 298 group and 384 field quiescent early-type…
Holographic dark energy described at the Hubble length
Iván Durán, Luca Parisi
We consider holographic cosmological models of dark energy in which the infrared cutoff is set by the Hubble's radius. We show that any interacting dark energy model with a matter…
High redshift cosmography: new results and implication for dark energy
Marek Demianski, Ester Piedipalumbo, Claudio Rubano +1
The explanation of the accelerated expansion of the Universe poses one of the most fundamental questions in physics and cosmology today. If the acceleration is driven by some form…
Testing the dark energy with gravitational lensing statistics
Shuo Cao, Giovanni Covone, Zong-Hong Zhu
We study the redshift distribution of two samples of early-type gravitational lenses, extracted from a larger collection of 122 systems, to constrain the cosmological constant in t…
Accelerating f(T) gravity models constrained by recent cosmological data
Vincenzo F. Cardone, Ninfa Radicella, Stefano Camera
Generalised Teleparallel gravity, also referred to as f(T) gravity, has been recently proposed as an extended theory of gravitation able to give rise to an accelerated expansion in…
Cosmological lepton asymmetry with a nonzero mixing angle θ_{13}
Emanuele Castorina, Urbano Franca, Massimiliano Lattanzi +4
While the baryon asymmetry of the Universe is nowadays well measured by cosmological observations, the bounds on the lepton asymmetry in the form of neutrinos are still significant…
Cosmography and constraints on the equation of state of the Universe in various parametrizations
Alejandro Aviles, Christine Gruber, Orlando Luongo +1
We use cosmography to present constraints on the kinematics of the Universe, without postulating any underlying theoretical model. To this end, we use a Monte Carlo Markov Chain an…
Measuring cosmological distances by coalescing binaries
Ivan De Martino, Salvatore Capozziello, Mariafelicia De Laurentis +1
Gravitational waves detected from well-localized inspiraling binaries would allow us to determine, directly and independently, binary luminosity and redshift. In this case, such sy…
Testing Yukawa-like potentials from f(R)-gravity in elliptical galaxies
N. R. Napolitano, S. Capozziello, A. J. Romanowsky +2
We present the first analysis of extended stellar kinematics of elliptical galaxies where a Yukawa--like correction to the Newtonian gravitational potential derived from f(R)-gravi…
First Low-Latency LIGO+Virgo Search for Binary Inspirals and their Electromagnetic Counterparts
The LIGO Scientific Collaboration, The Virgo Collaboration
Aims. The detection and measurement of gravitational-waves from coalescing neutron-star binary systems is an important science goal for ground-based gravitational-wave detectors. I…
