A Hubble diagram (HD) has recently been constructed in the redshift range 0 ≲ z ≲ 6.5 using a nonlinear relation between the ultraviolet (UV) and X-ray...
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...
Cosmology and the massive photon frequency shift in the Standard-Model Extension
The total red shift z might be recast as a combination of the expansion red shift and a static shift due to the energy-momentum tensor non-conservation of a...
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...
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...
The theory that predicts how the lightest elements formed after the Big Bang has hitherto failed to explain the amount of cosmic lithium. The detection of...
CosmoMIA: cosmic web-based redshift space halo distribution
Modern galaxy surveys demand extensive survey volumes and resolutions surpassing current dark matter-only simulations' capabilities. To address this, many...
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...
