Future sensitivity of neutrino telescopes to dark matter annihilations from the cosmic diffuse neutrino signal
Angeles Moline, Alejandro Ibarra, Sergio Palomares-Ruiz
Cosmological observations and cold dark matter N-body simulations indicate that our Universe is populated by numerous halos, where dark matter particles annihilate, potentially pro…
Statistics of Microlensing Caustic Crossings in Q~2237+0305: Peculiar Velocity of the Lens Galaxy and Accretion Disk Size
E. Mediavilla, J. Jimenez-Vicente, J. A. Muñoz +2
We use the statistics of caustic crossings induced by microlensing in the lens system Q~2237+0305 to study the lens galaxy peculiar velocity. We calculate the caustic crossing rate…
Phenomenological approaches of inflation and their equivalence
Lotfi Boubekeur, Elena Giusarma, Olga Mena +1
In this work, we analyze two possible alternative and model-independent approaches to describe the inflationary period. The first one assumes a general equation of state during inf…
Current constraints on early and stressed dark energy models and future 21 cm perspectives
Maria Archidiacono, Laura Lopez-Honorez, Olga Mena
Despite the great progress of current cosmological measurements, the nature of the dominant component of the universe, coined dark energy, is still an open question. Early Dark Ene…
Revisiting cosmological bounds on sterile neutrinos
Aaron C. Vincent, Enrique Fernandez Martinez, Pilar Hernandez +2
We employ state-of-the art cosmological observables including supernova surveys and BAO information to provide constraints on the mass and mixing angle of a non-resonantly produced…
On the current status of Modified Gravity
Lotfi Boubekeur, Elena Giusarma, Olga Mena +1
We revisit the cosmological viability of the Hu Sawicki modified gravity scenario. The impact of such a modification on the different cosmological observables, including gravi…
Inflating an Inhomogeneous Universe
Richard Easther, Layne C. Price, Javier Rasero
While cosmological inflation can erase primordial inhomogeneities, it is possible that inflation may not begin in a significantly inhomogeneous universe. This issue is particularly…
A model-independent fit to Planck and BICEP2 data
Laura Barranco, Lotfi Boubekeur, Olga Mena
Inflation is the leading theory to describe elegantly the initial conditions that led to structure formation in our universe. In this paper, we present a novel phenomenological fit…
Axion cold dark matter: status after Planck and BICEP2
E. Di Valentino, E. Giusarma, M. Lattanzi +2
We investigate the axion dark matter scenario (ADM), in which axions account for all of the dark matter in the Universe, in light of the most recent cosmological data. In particula…
Systematic uncertainties from halo asphericity in dark matter searches
Nicolas Bernal, Jaime E. Forero-Romero, Raghuveer Garani +1
Although commonly assumed to be spherical, dark matter halos are predicted to be non-spherical by N-body simulations and their asphericity has a potential impact on the systematic…
Cosmology in a certain vector-tensor theory of gravitation
Roberto Dale, Diego Sáez
We study relevant cosmological topics in the framework of a certain vector-tensor theory of gravitation (hereafter VT). This theory is first compared with the so-called extended el…
Relic Neutrinos, thermal axions and cosmology in early 2014
Elena Giusarma, Eleonora Di Valentino, Massimiliano Lattanzi +2
We present up to date cosmological bounds on the sum of active neutrino masses as well as on extended cosmological scenarios with additional thermal relics, as thermal axions or st…
On the universality of void density profiles
E. Ricciardelli, V. Quilis, J. Varela
The massive exploitation of cosmic voids for precision cosmology in the upcoming dark energy experiments, requires a robust understanding of their internal structure, particularly…
The ALHAMBRA survey: an empirical estimation of the cosmic variance for merger fraction studies based on close pairs
C. López-Sanjuan, A. J. Cenarro, C. Hernández-Monteagudo +27
Our goal is to estimate empirically, for the first time, the cosmic variance that affects merger fraction studies based on close pairs. We compute the merger fraction from photomet…
The Average Size and Temperature Profile of Quasar Accretion Disks
J. Jiménez-Vicente, E. Mediavilla, C. S. Kochanek +4
We use multi-wavelength microlensing measurements of a sample of 10 image pairs from 8 lensed quasars to study the structure of their accretion disks. By using spectroscopy or narr…
