Probing the early Universe with gravitational Wave Background
We will review both theoretical and obsevational aspects of gravitational wave backgrounds of cosmological origin. We will present a classifcation of...
Testing Newtonian gravity in the low acceleration regime with globular clusters: the case of ω Centauri revisited
Context. Stellar kinematics in the external regions of globular clusters can be used to probe the validity of Newton's law in the low acceleration regimes...
Testing Newtonian gravity with distant globular clusters: NGC 1851 and NGC 1904
Context. Globular clusters are useful for testing the validity of Newtonian dynamics in the low acceleration regime typical of galaxies, without the...
We examine the ability to test the black hole no-hair theorem at the 10% level in this decade using the binary black hole in OJ287. In the test we constrain the...
The Anomalous Acceleration of the Pioneer Spacecrafts
Radiometric data from the Pioneer 10 and 11 spacecrafts have revealed an unexplained constant acceleration of a_A = (8.74+/-1.33)×10^{-10}m s^{-2} towards the...
The clustering of galaxies in the SDSS-III Baryon Oscillation Spectroscopic Survey: measuring growth rate and geometry with anisotropic clustering
We use the observed anisotropic clustering of galaxies in the Baryon Oscillation Spectroscopic Survey Data Release 11 CMASS sample to measure the linear growth...
We have developed a generalization of the Zeldovich approximation that is exact in a wide variety of situations, including planar, spherical, and cylindrical...
The correlation structure of dark matter halo properties
We investigate the correlation between nine different dark matter halo properties using a rank correlation analysis and a Principal Component Analysis for a...
The COSMOS-Web ring: In-depth characterization of an Einstein ring lensing system at z ∼ 2
Aims: We provide an in-depth analysis of the COSMOS-Web ring, an Einstein ring at z ≈ 2 that we serendipitously discovered during the data reduction of the...
