London BSM Meeting

Monday 20 Apr 2026, 09:00 → 19:30 Europe/London

Bush House Lecture Theatre 2 BH(S)4.04 (King's College London)

Sebastian Ellis (University of London (GB)), Tevong You (King's College London)

The London BSM meeting aims to gather researchers interested in all aspects of physics Beyond the Standard Model (BSM) and related areas for a half-day of talks and discussion.  

The talks will be held in Bush House South building Lecture Theatre 2 room BH(S)4.04. Please register as a visitor at the Bush House South building main entrance. One of us will be there to help during the registration.

Coffee and lunch vouchers will be provided. These can be used in the Bush house basement cafeteria, in the Arcade cafe on the ground floor of Bush House North building (closes at 3pm) and in the Chapters cafe on the 2nd floor of the Strand building (closes at 4pm).  

If you arrive late and have trouble registering as a visitor with security, please email tevong.you@kcl.ac.uk, sebastian.ellis@kcl.ac.uk, victor.maura_breick@kcl.ac.uk, maximilian.detering@kcl.ac.uk, and one of us will come sign you in.

11:00 → 11:50 Diego Redigolo - Post-Recombination Fluctuations from a Sequestered Dark Sector

I will present a formalism to characterize the imprints of post-recombination fluctuation sources.
I will consider a sequestered dark sector interacting only gravitationally with the Standard Model
and dark matter. For dynamics on timescales much shorter than the Hubble time, stress-tensor
conservation restricts the source to continuous contributions and instantaneous injections of pressure
and anisotropic stress. The latter dominates the integrated Sachs–Wolfe signal, enabling strong
constraints on such sources from the Cosmic Microwave Background. As an example, I will bound the
allowed dark-sector energy density for late first-order phase transitions. If times permits I will also discuss extension
of this framework before recombination.
