AtLAST -- A five fold increase in the number of identified Strongly Lensed Galaxies in the sub-millimetre and its consequences

Joaquín 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

Joaquín 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…

Cosmic magnification on multi-catalogue Herschel submillimetre galaxies

R. Fernandez-Fernandez, M. M. Cueli, J. González-Nuevo +6

{Submillimetre galaxies (SMGs) are excellent background sources for magnification-bias studies, but the limited sky coverage in the submillimetre (sub-mm) band constrains their sta…

Candidate gravitationally lensed submillimeter galaxies in Herschel-ATLAS associated with WISE elliptical counterparts

Juan Alberto Cano, Joaquín González-Nuevo, Laura Bonavera +5

We present a new and independent methodology for identifying gravitational lens candidates using data from the H-ATLAS and AllWISE surveys. Unlike previous approaches, which are ty…

Signal Drop in Magnification Profiles: Combining Lensing Simulations and Observations

David Crespo, Joaquín González-Nuevo, Laura Bonavera +4

Gravitational lensing magnification bias is a valuable tool for studying mass density profiles, with submillimetre galaxies (SMGs) serving as ideal background sources. The satellit…
