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

Prof. Joaquín González-Nuevo (Universidad de Oviedo -- ICTEA)

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....

6. The Magnetised Cosmic Web: Joint RM and SZ Probes with AtLAST

Shane O'Sullivan (IPARCOS UCM)

04/06/2026, 12:30

Contributed talk

Magnetic fields are now known to permeate the full hierarchy of cosmic structure, from galaxies and clusters to filaments and the most diffuse phases of the cosmic web. However, their origin and evolution remain poorly constrained, particularly in low-density environments where direct observational probes are scarce.
In this talk, I will present recent progress in tracing the magnetised...

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

Sunil Malik (Complutense University of Madrid)

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...
