Constraining LLTB models with galaxy cluster counts from next generation surveys
Ziad Sakr, Ana Carvalho, Antonio Da Silva +7
The Universe's assumed homogeneity and isotropy is known as the cosmological principle. It is one of the assumptions that lead to the Friedmann-Lema\^ıtre-Robertson-Walker (FLRW) m…
Fast emulation of cosmological density fields based on dimensionality reduction and supervised machine-learning
Miguel Conceição, Alberto Krone-Martins, Antonio da Silva +1
N-body simulations are the most powerful method to study the non-linear evolution of large-scale structure. However, they require large amounts of computational resources, making u…
New Horizons for Fundamental Physics with LISA
K. G. Arun, Enis Belgacem, Robert Benkel +138
The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders about the fundamental theory of nature at play in the extreme gravity regime, where the gravitatio…
Cosmology with the Laser Interferometer Space Antenna
Pierre Auclair, David Bacon, Tessa Baker +177
The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravita…
Faint objects in motion: the new frontier of high precision astrometry
Fabien Malbet, Céline Boehm, Alberto Krone-Martins +83
Sky survey telescopes and powerful targeted telescopes play complementary roles in astronomy. In order to investigate the nature and characteristics of the motions of very faint ob…
Effect of Priomordial non-Gaussianities on Galaxy Clusters Scaling Relations
A. M. M. Trindade, Antonio da Silva
Galaxy clusters are a valuable source of cosmological information. Their formation and evolution depends on the underlying cosmology and on the statistical nature of the primordial…
PRISM (Polarized Radiation Imaging and Spectroscopy Mission): An Extended White Paper
PRISM Collaboration, Philippe André, Carlo Baccigalupi +140
PRISM (Polarized Radiation Imaging and Spectroscopy Mission) was proposed to ESA in May 2013 as a large-class mission for investigating within the framework of the ESA Cosmic Visio…
An approach for the detection of point-sources in very high resolution microwave maps
R. Vio, P. Andreani, E. P. R. G. Ramos +1
This paper deals with the detection problem of extragalactic point-sources in multi-frequency, microwave sky maps that will be obtainable in future cosmic microwave background radi…
Euclid Mission: building of a Reference Survey
J. Amiaux, R. Scaramella, Y. Mellier +28
Euclid is an ESA Cosmic-Vision wide-field-space mission which is designed to explain the origin of the acceleration of Universe expansion. The mission will investigate at the same…
Two modified ILC methods to detect point sources in Cosmic Microwave Background maps
R. Vio, P. Andreani, E. P. R. G. Ramos +1
We propose two detection techniques that take advantage of a small sky area approximation and are based on modifications of the "internal linear combination" (ILC) method, an appro…
Measuring the redshift dependence of the CMB monopole temperature with PLANCK data
Ivan de Martino, Fernando Atrio-Barandela, Antonio da Silva +4
We study the power of PLANCK data to constrain deviations of the Cosmic Microwave Background black body temperature from adiabatic evolution using the thermal Sunyaev-Zeldovich ani…
The XMM Cluster Survey: Predicted overlap with the Planck Cluster Catalogue
Pedro T. P. Viana, António da Silva, Elsa P. R. G. Ramos +13
We present a list of 15 clusters of galaxies, serendipitously detected by the XMM Cluster Survey (XCS), that have a high probability of detection by the Planck satellite. Three of…
The impact of dust on the scaling properties of galaxy clusters
Antonio C. da Silva, Andrea Catalano, Ludovic Montier +3
We investigate the effect of dust on the scaling properties of galaxy clusters based on hydrodynamic N-body simulations of structure formation. We have simulated five dust models p…
The impact of cooling and pre-heating on the Sunyaev-Zel'dovich effect
Antonio C da Silva, Scott T Kay, Andrew R Liddle +3
We use hydrodynamical simulations to assess the impact of radiative cooling and `pre-heating' on predictions for the Sunyaev--Zel'dovich (SZ) effect. Cooling significantly reduces…
Hydrodynamical simulations of the Sunyaev-Zel'dovich effect: the kinetic effect
Antonio C da Silva, Domingos Barbosa, Andrew R Liddle +1
We use hydrodynamical N-body simulations to study the kinetic Sunyaev-Zel'dovich effect. We construct sets of maps, one square degree in size, in three different cosmological model…
Hydrodynamical simulations of the Sunyaev--Zel'dovich effect
Antonio C da Silva, Domingos Barbosa, Andrew R Liddle +1
We use a hydrodynamical N-body code to generate simulated maps, of size one square degree, of the thermal SZ effect. We study three different cosmologies; the currently-favoured lo…
