Cosmography with DESI-DR1 Cosmic Chronometers: Direct H(z) measurements from Luminous Red Galaxy ages
Carlos A. Álvarez, Marcos M. Cueli, Balakrishna S. Haridasu +6
Providing robust redshift estimates for almost 3 million luminous red galaxies (LRGs), the Dark Energy Spectroscopic Instrument (DESI) offers a unique opportunity to test the expan…
Spatial Variations of Polarized Synchrotron Emission in the QUIJOTE MFI Data using Neural Networks
J. M. Casas, L. Bonavera, J. González-Nuevo +7
Polarized synchrotron emission from ultra-relativistic electrons spiraling the Galactic magnetic field has become one of the most relevant emissions in the Interstellar medium thes…
Methodological refinement of the submillimeter galaxy cross-correlation function measurements and their uncertainty estimation
J. González-Nuevo, L. Bonavera, M. M. Cueli +2
In this study, we aim to develop a new methodology to estimate the cross-correlation function and uncertainties and apply it to the analysis of magnification bias in galaxy surveys…
AtLAST -- A five fold increase in the number of identified Strongly Lensed Galaxies in the sub-millimetre and its consequences
JoaquÃn González-Nuevo, Laura Bonavera, Juan Alberto Cano +6
Strong gravitational lensing is a powerful probe of cosmology, dark matter (DM), and high-redshift galaxy evolution, but current samples of strongly lensed galaxies (SLGs) remain f…
AtLAST -- Determination of Halo Mass Density Profiles at kpc Scales through Magnification Bias
JoaquÃn González-Nuevo, Laura Bonavera, Juan Alberto Cano +9
Magnification bias, the lensing-induced modification of background source number counts, provides a uniquely powerful probe of the mass density profiles of galaxies and clusters do…
AtLAST -- Cosmology with submillimetre galaxies magnification bias
Laura Bonavera, Joaquin Gonzalez-Nuevo, Juan Alberto Cano +10
Magnification bias offers a uniquely powerful and independent route to cosmological information. As a gravitational-lensing observable, it probes galaxy-matter correlations without…
