Cosmology with Euclid: an Overview

The Euclid mission, launched in July 2023 by the European Space Agency, is set to revolutionise our understanding of the Universe by probing the nature of dark energy, dark matter, and fundamental physics with unprecedented precision. By surveying approximately one third of the sky, Euclid will create a 3D map of the Universe observing around 1.5 billion galaxies across 10 billion years of cosmic history. In this talk, I will provide an overview of Euclid’s scientific goals and its unique observational strategy. I will focus on the “3x2pt analysis”—combining weak lensing and galaxy clustering measurements—as a powerful tool to constrain modifications to General Relativity, neutrino masses, and the nature of dark energy. Additionally, I will discuss the computational challenges posed by Euclid’s unprecedented dataset, and highlight the role of advanced statistical methods and machine learning in tackling them.

Basil Hiley (1935–2025)

It is with great sadness that we wish to inform you that Professor Basil Hiley passed away peacefully on Saturday the 25th of January at the age of 89.

He will be remembered by many as a great physicist, one who was always willing to follow his intuition while backing up his ideas with a phenomenal knowledge and insight in to physics. He was also a hugely generous person, keen to share his ideas and collaborate with many of us in the department - young and old alike.

UCL Provost visits CERN

In January 2025, UCL's President and Provost, Dr Michael Spence, visited CERN, alongside a UCL delegation for an in-depth look at some of the world's most groundbreaking scientific advancements, and to explore opportunities for strengthening the UCL-CERN collaborations.

High Energy Physics

The UCL high energy physics group has 50 academic, research and technical staff and over 50 PhD students. We are one of the largest groups in the country with research areas spanning: theory/phenomenology, detector, software and accelerator R&D and analysis of data from the LHC, dark matter and neutrino experiments.

LZ experiment sets new record in search for dark matter

LZ experiment sets new record in search for dark matter

New results from the LUX-ZEPLIN (LZ) collaboration involving UCL researchers have put the best-ever limits on weakly interacting massive particles (WIMPs), a leading candidate for what makes up our universe’s invisible mass.

New measurement of particle wobble hints at new physics

New measurement of particle wobble hints at new physics

A new, ultraprecise measurement of the subatomic muon particle’s anomalous magnetic moment, conducted at US-based Fermilab and involving researchers from UCL, reinforces a discrepancy between theory and experiment that physicists can’t explain, potentially hinting at new physics.

UCL HEP Research Fellowships

We are keen to support a limited number of strong candidates in applying for Research Fellowships. If your profile and interests match our activities, we would be very interested to hear from you.
