We propose a systematic study of the environments of a representative sample of Radio Loud Quasars (RLQ) and Radio Quiet Quasars (RQQ) in two different redshift...

We present deep Ka-band (ν~ 33 GHz) observations of the cosmic microwave background (CMB) made with the extended Very Small Array (VSA). This configuration...

The High-Velocity Clouds (HVCs) observed in the Galactic neighbourhood, have been proposed to be remnants of the formation of the galaxies in the Local Group...

We investigate higher order symplectic integration strategies within Bayesian cosmic density field reconstruction methods. In particular, we study the fourth...

We study the density profiles of collapsed galaxy-size dark matter halos with masses 1011 to 5×1012 Msolar focusing mostly on the halo outer regions from the...

Statistical analyses of measurements of the Hubble-Lemaître constant H 0 (163 measurements between 1976 and 2019) show that the statistical error bars...

Context. Cosmic chronometers may be used to measure the age difference between passively evolving galaxy populations to calculate the Hubble parameter H(z) as a...

We investigate the impact of a stochastic background of primordial magnetic fields (PMF) generated before recombination on the ionization history of the...

We develop a methodology to optimize the measurement of baryon acoustic oscillation (BAO) from a given galaxy sample. In our previous work, we demonstrated that...
