  • 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...

    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...

    Could dark energy be measured in the lab?
    The experimentally measured spectral density of current noise in Josephson junctions provides direct evidence for the existence of zero-point fluctuations...
  • Publication
    Counts-in-cylinders in the Sloan Digital Sky Survey with Comparisons to N-body Simulations
    Environmental statistics provide a necessary means of comparing the properties of galaxies in different environments, and a vital test of models of galaxy...
  • Publication
    Covariance matrices for variance-suppressed simulations
    Cosmological N-body simulations provide numerical predictions of the structure of the Universe against which to compare data from ongoing and future surveys...
