26. Advancing W-Band KIDs for Low-Frequency Millimeter-Wave Astronomy

Víctor Rollano (Centro de Astrobiología (INTA-CSIC))

Invited talk

Superconducting detectors offer a powerful alternative to classical coherent receivers. Microwave Kinetic Inductance Detectors (KIDs) are a type of superconducting detector that combines intrinsic frequency multiplexing with a simple cryogenic harness, making them attractive candidates for astronomical observatories. In particular, KIDs have already demonstrated outstanding performance in...

3. Magnification bias as an independent cosmological probe

Contributed talk

Magnification bias offers a powerful and independent route to cosmological information, probing galaxy-matter correlations without relying on galaxy shapes, PSF modelling, or intrinsic-alignment corrections. Its sensitivity spans both geometry and growth: it simultaneously constrains the matter density, the amplitude of structure, and crucially the redshift evolution of dark energy below z≤1....

13. Magnetic field in the circumgalactic medium of high-redshift galaxies using ASKAP

Contributed talk

Magnetic fields are ubiquitous in galaxies and play a fundamental role in their dynamics and evolution. However, observational constraints on magnetic fields in the Circumgalactic Medium (CGM), particularly at intermediate to high z, remain limited. In this work, we investigate CGM magnetisation using a large sample of quasar Rotation Measures (RMs) from ASKAP, statistically separating...

17. Extended Molecular Gas in Protoclusters: A Science Case for AtLAST

Helmut Dannerbauer (Instituto de Astrofísica de Canarias)

Contributed talk

The Atacama Large Aperture Submillimeter Telescope (AtLAST) will open a new window on the cold molecular gas content of galaxies across cosmic time. With its wide-field mapping, high surface-brightness sensitivity, and ability to detect low-J CO emission, AtLAST will trace diffuse, extended molecular gas in dense environments at high redshift. This is key to understanding how environmental...
