A new look at Sco OB1 association with Gaia DR2
L. Yalyalieva, G. Carraro, R. Vazquez +3
We present and discuss photometric optical data in the area of the OB association Sco OB1 covering about 1 squared degree. UBVI photometry is employed in tandem with Gaia DR2 data…
Consistency relations for large-scale structures: Applications for the integrated Sachs-Wolfe effect and the kinematic Sunyaev-Zeldovich effect
Luca Alberto Rizzo, David F. Mota, Patrick Valageas
Consistency relations of large-scale structures provide exact nonperturbative results for cross-correlations of cosmic fields in the squeezed limit. They only depend on the equival…
Simulating cosmologies beyond CDM with PINOCCHIO
Luca Alberto Rizzo, Francisco Villaescusa-Navarro, Pierluigi Monaco +4
We present a method that extends the capabilities of the PINpointing Orbit-Crossing Collapsed HIerarchical Objects (PINOCCHIO) code, allowing it to generate accurate dark matter ha…
Non-zero density-velocity consistency relations for large scale structures
Luca Alberto Rizzo, David F. Mota, Patrick Valageas
We present exact kinematic consistency relations for cosmological structures that do not vanish at equal times and can thus be measured in surveys. These rely on cross-correlations…
Supersymmetric chameleons and ultra-local models
Philippe Brax, Luca Alberto Rizzo, Patrick Valageas
Super-chameleon models where all types of matter belong to three secluded sectors, i.e. the dark, supersymmetry breaking and matter sectors, are shown to be dynamically equivalent…
Ultra-local models of modified gravity without kinetic term
Philippe Brax, Luca Alberto Rizzo, Patrick Valageas
We present a class of modified-gravity theories which we call ultra-local models. We add a scalar field, with negligible kinetic terms, to the Einstein-Hilbert action. We also intr…
Binary open clusters in the Milky Way: photometric and spectroscopic analysis of NGC 5617 and Trumpler 22
G. M. De Silva, G. Carraro, V. D'Orazi +4
Using photometry and high resolution spectroscopy we investigate for the first time the physical connection between the open clusters NGC 5617 and Trumpler 22. Based on new CCD pho…
Testing Modified Gravity with Cosmic Shear
Joachim Harnois-Déraps, Dipak Munshi, Patrick Valageas +4
We use the cosmic shear data from the Canada-France-Hawaii Telescope Lensing Survey to place constraints on and {\it Generalized Dilaton} models of modified gravity. This is…
K-mouflage effects on clusters of galaxies
Philippe Brax, Luca Alberto Rizzo, Patrick Valageas
We investigate the effects of a K-mouflage modification of gravity on the dynamics of clusters of galaxies. We extend the description of K-mouflage to situations where the scalar f…
