Descripción
El Fondo Cósmico de Microondas (FCM) contiene la información estadística de las semillas primigenias que han dado lugar a la formación de todas las estructuras en el Universo. Su contrapartida natural en el Universo local es la distribución de las galaxias que surgen como resultado del crecimiento gravitatorio de aquellas fluctuaciones de densidad primigenias. La caracterización de la distribución de inhomogeneidades a gran escala en el Universo local proporciona una herramienta muy poderosa, y complementaria al FCM, para determinar el origen y el contenido energético del Universo, el ritmo de expansión del mismo durante la evolución cósmica, los detalles del proceso de formación de todas las estructuras a gran escala que observamos en el Universo hoy día. Esta es la página web del grupo de Cosmología con trazadores de la Estructura a Gran Escala (LSS de sus siglas en inglés), en el IAC.

Euclid Preparation. XIV. The Complete Calibration of the Color-Redshift Relation (C3R2) Survey: Data Release 3The Complete Calibration of the Color-Redshift Relation (C3R2) survey is obtaining spectroscopic redshifts in order to map the relation between galaxy color and redshift to a depth of i ~ 24.5 (AB). The primary goal is to enable sufficiently accurate photometric redshifts for Stage IV dark energy projects, particularly Euclid and the Nancy GraceStanford, S. A. et al.

Relation of internal attenuation, dust emission, and the size of spiral galaxies. Calibration at low-z and how to use it as a cosmological test at high-zAims: Dust in spiral galaxies produces emission in the far-infrared (FIR) and internal absorption in visible wavelengths. However, the relation of the two amounts is not trivial because optical absorption may saturate, but the FIR emission does not. Moreover, the volume concentration of dust plays a role in the relation of absorption and emissionLópez-Corredoira, M. et al.

Dark Energy Survey Year 3 results: Curved-sky weak lensing mass map reconstructionWe present reconstructed convergence maps, mass maps, from the Dark Energy Survey (DES) third year (Y3) weak gravitational lensing data set. The mass maps are weighted projections of the density field (primarily dark matter) in the foreground of the observed galaxies. We use four reconstruction methods, each is a maximum a posteriori estimate withJeffrey, N. et al.

Cosmological parameter forecasts by a joint 2D tomographic approach to CMB and galaxy clusteringThe cross-correlation between the cosmic microwave background (CMB) fields and matter tracers carries important cosmological information. In this paper, we forecast by a signal-to-noise ratio analysis the information contained in the cross-correlation of the CMB anisotropy fields with source counts for future cosmological observations and itsBermejo-Climent, José Ramón et al.

Simultaneous modelling of matter power spectrum and bispectrum in the presence of baryonsWe demonstrate that baryonification algorithms, which displace particles in gravity-only simulations according to physically motivated prescriptions, can simultaneously capture the impact of baryonic physics on the two and three-point statistics of matter. Specifically, we show that our implementation of a baryonification algorithm jointly fits theAricò, Giovanni et al.

Density weighted angular redshift fluctuations: a new cosmological observableWe propose the use of angular fluctuations in the galaxy redshift field as a new way to extract cosmological information in the Universe. This new probe $\delta z (\hat{\mathbf {n}})$ consists of the statistics of sky maps built by projecting redshifts under a Gaussian window of width σ z centred upon a redshift z obs, and weighted by the galaxyHernández-Monteagudo, Carlos et al.

Euclid preparation. XI. Mean redshift determination from galaxy redshift probabilities for cosmic shear tomographyThe analysis of weak gravitational lensing in wide-field imaging surveys is considered to be a major cosmological probe of dark energy. Our capacity to constrain the dark energy equation of state relies on an accurate knowledge of the galaxy mean redshift ⟨z⟩. We investigate the possibility of measuring ⟨z⟩ with an accuracy better than 0.002 (1 + zEuclid Collaboration et al.

Exact Semianalytical Calculation of Rotation Curves with Bekenstein-Milgrom Nonrelativistic MONDAstronomers derive MOdified Newtonian Dynamics (MOND) rotation curves using the simple algebraic rule of calculating the acceleration as equal to the Newtonian acceleration (a) divided by some factor μ(a). However, there are velocity differences between this simple rule and the calculation derived from more sophisticated MOND versions such as AQUALLópez-Corredoira, M. et al.

Higher order Hamiltonian Monte Carlo sampling for cosmological large-scale structure analysisWe investigate higher order symplectic integration strategies within Bayesian cosmic density field reconstruction methods. In particular, we study the fourth-order discretization of Hamiltonian equations of motion (EoM).

Cosmology and the massive photon frequency shift in the Standard-Model ExtensionThe total red shift z might be recast as a combination of the expansion red shift and a static shift due to the energy-momentum tensor non-conservation of a photon propagating through Electro-Magnetic (EM) fields. If massive, the photon may be described by the de Broglie-Proca (dBP) theory which satisfies the Lorentz(-Poincaré) Symmetry (LoSy) butSpallicci, Alessandro D. A. M. et al.

Constraining primordial non-Gaussianity with postreconstructed galaxy bispectrum in redshift spaceGalaxy bispectrum is a promising probe of inflationary physics in the early Universe as a measure of primordial non-Gaussianity (PNG), whereas its signal-to-noise ratio is significantly affected by the mode coupling due to nonlinear gravitational growth.
