The J-PLUS collaboration. Additive versus multiplicative systematics in surveys of the large scale structure of the Universe
C. Hernández-Monteagudo, G. Aricò, J. Chaves-Montero +19
Observational and/or astrophysical systematics modulating the observed number of luminous tracers can constitute a major limitation in the cosmological exploitation of surveys of t…
Morpho-statistical characterisation of the spatial galaxy distribution through Gibbs point processes
Lluís Hurtado-Gil, Radu S. Stoica, Vicent J. Martínez +1
This paper proposes a morpho-statistical characterisation of the galaxy distribution through spatial statistical modelling based on inhomogeneous Gibbs point processes. The galaxy…
The miniJPAS survey: a preview of the Universe in 56 colours
S. Bonoli, A. Marín-Franch, J. Varela +166
The Javalambre-Physics of the Accelerating Universe Astrophysical Survey (J-PAS) will soon start to scan thousands of square degrees of the northern extragalactic sky with a unique…
The best fit for the observed galaxy Counts-in-Cell distribution function
Ll. Hurtado-Gil, V. J. Martínez, P. Arnalte-Mur +3
The Sloan Digital Sky Survey (SDSS) is the first dense redshift survey encompassing a volume large enough to find the best analytic probability density function that fits the galax…
Real- and redshift-space halo clustering in cosmologies
Pablo Arnalte-Mur, Wojciech A. Hellwing, Peder Norberg
We present two-point correlation function statistics of the mass and the halos in the chameleon modified gravity scenario using a series of large volume N-body simulations.…
Galaxy clusters and groups in the ALHAMBRA Survey
Begoña Ascaso, Narciso Benítez, Alberto Fernández-Soto +35
We present a catalogue of 348 galaxy clusters and groups with selected in the 2.78 ALHAMBRA Survey. The high precision of our photometric redshifts, close to $1…
Joint constraints on galaxy bias and through the N-pdf of the galaxy number density
Pablo Arnalte-Mur, Patricio Vielva, Vicent J. Martínez +3
We present a full description of the N-probability density function of the galaxy number density fluctuations. This N-pdf is given in terms, on the one hand, of the cold dark matte…
Shell-like structures in our cosmic neighbourhood
M. Einasto, P. Heinämäki, L. J. Liivamägi +6
Signatures of the processes in the early Universe are imprinted in the cosmic web. Some of them may define shell-like structures characterised by typical scales. We search for shel…
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 ALHAMBRA survey: evolution of galaxy clustering since
P. Arnalte-Mur, V. J. Martínez, P. Norberg +29
We study the clustering of galaxies as function of luminosity and redshift in the range using data from the Advanced Large Homogeneous Area Medium Band Redshift A…
The ALHAMBRA Survey: Bayesian Photometric Redshifts with 23 bands for 3 squared degrees
A. Molino, N. Benítez, M. Moles +30
The ALHAMBRA (Advance Large Homogeneous Area Medium Band Redshift Astronomical) survey has observed 8 different regions of the sky, including sections of the COSMOS, DEEP2, ELAIS,…
Uncertainty in 2-point correlation function estimators and BAO detection in SDSS DR7
Antoine Labatie, Jean-Luc Starck, Marc Lachièze-Rey +1
We study the uncertainty in different two-point correlation function (2PCF) estimators in currently available galaxy surveys. This is motivated by the active subject of using the b…
Measuring galaxy segregation using the mark connection function
Vicent J. Martinez, Pablo Arnalte-Mur, Dietrich Stoyan
(abridged) The clustering properties of galaxies belonging to different luminosity ranges or having different morphological types are different. These characteristics or `marks' pe…
