Astrophysical: Cosmology

  • Publication
    Cosmology and fundamental physics with the ELT-ANDES spectrograph
    State-of-the-art 19th century spectroscopy led to the discovery of quantum mechanics, and 20th century spectroscopy led to the confirmation of quantum...
  • Publication
    Cosmology from cross-correlation of ACT-DR4 CMB lensing and DES-Y3 cosmic shear
    Cross-correlation between weak lensing of the Cosmic Microwave Background (CMB) and weak lensing of galaxies offers a way to place robust constraints on...
  • Publication
    Cosmology with galaxy-galaxy lensing on non-perturbative scales: emulation method and application to BOSS LOWZ
    We describe our non-linear emulation (i.e. interpolation) framework that combines the halo occupation distribution (HOD) galaxy bias model with N-body...
  • Project
    Cosmology with Large Scale Structure Probes
    The Cosmic Microwave Background (CMB) contains the statistical information about the early seeds of the structure formation in our Universe. Its natural...
  • Publication
    Cosmology with second- and third-order shear statistics for the Dark Energy Survey: Methods and simulated analysis
    We present a new pipeline designed for the robust inference of cosmological parameters using both second- and third-order shear statistics. We build a...
  • Publication
    Cosmology with Supernova Encore in the Strong Lensing Cluster MACS J0138─2155: Time Delays and Hubble Constant Measurement
    Multiply imaged supernovae (SNe) provide a novel means of constraining the Hubble constant (H 0). Such measurements require a combination of precise models of...

    COSMOSOMAS observations of the cosmic microwave background and Galactic foregrounds at 11 GHz: evidence for anomalous microwave emission at high Galactic latitude
    We present observations with the new 11-GHz radiometer of the COSMOSOMAS experiment at the Teide Observatory (Tenerife). The sky region between 0°

    COSMOSOMAS: a circular scanning instrument to map the sky at centimetric wavelengths
    We describe the first instrument of a cosmic microwave background experiment for mapping cosmological structures on medium angular scales (the COSMOSOMAS...
