Title: New Approaches in Modelling and Interpretation of the Cosmic Dawn 21-cm Signal
Title: New Approaches in Modelling and Interpretation of the Cosmic Dawn 21-cm Signal
Abstract: The 21-cm signal is a powerful probe of the high-redshift universe, offering a unique window into the cosmic dawn and the dark ages. In this talk, I will introduce the fundamentals of 21-cm cosmology and highlight its advantages in studying the early universe. Through specific examples, I will illustrate how the 21-cm signal can be used to constrain the nature of dark matter, provide independent confirmation of an excess radio background, and make predictions for galaxy surveys. Finally, I will present ECHO21, a new Python package designed to efficiently generate a large suite of models spanning the dark ages and cosmic dawn.

Title: Imaging the unimagable with the Hanbury Brown and Twiss effect
Title: Imaging the unimagable with the Hanbury Brown and Twiss effect
Abstract: The sharpest images ever made (in the sense of angular resolution) are all at radio wavelengths --- most famously the black hole shadows reconstructed from the Event Horizon Telescope. Can comparable angular resolution be achieved at optical wavelengths? This talk will draw attention to several recent research groups who are attempting just that. Â The key is to exploit a quantum-optical phenomenon known as the Hanbury Brown & Twiss (HBT) effect. Â Most of the targets are stars, but there are more exotic things to image too...
