<p class="xmsonormal"><span style="font-family:"Aptos",sans-serif;color:black">After a decade of gravitational-wave detections, the field is entering a new era. With next-generation detectors on the horizon, the key question is no longer how many sources we
will observe, but how much physics we can extract from them. Addressing this challenge requires moving beyond some of the simplifying assumptions used in most studies so far, such as circular orbits, aligned spins, or black holes evolving in vacuum. Paradoxically,
it is precisely these complexities that may encode the richest opportunities for gravitational waves to reveal new astrophysical phenomena and, potentially, new fundamental physics.<o:p></o:p></span></p>
<p class="xmsonormal"><span style="font-family:"Aptos",sans-serif;color:black">In this talk, I will focus on one such scenario by discussing how astrophysical environments can influence black hole binaries. In particular, I will describe the signatures that
superradiant boson clouds may imprint on gravitational-wave signals and outline the modelling tools being developed to accurately capture the dynamics of these systems. I will also highlight the key open problems and challenges that must be addressed to fully
realise this potential.<o:p></o:p></span></p>

<p class="xmsonormal"><span style="font-family:"Aptos",sans-serif;color:black">The Epoch of Reionization (EoR) follows the end of the Dark Ages of the Universe and signals the birth of the first stars. The aim of the current generation of radio telescopes is
to make the first statistical detection of this epoch, covering 400 million - 1 billion years after the Big Bang. For the next generation Square Kilometre array, we will have an order of magnitude improved sensitivity and can pursue imaging over this time.
However, foregrounds cover the cosmological data by several orders of magnitude, and their removal remains a significant challenge. It has been over a decade since we turned on the current generation telescope LOFAR, and still there is no detection… should
we just give up?<o:p></o:p></span></p>

<p class="xmsonormal"><span style="font-family:"Aptos",sans-serif;color:black">Strong gravitational lensing provides a natural probe for dark matter distributions around galaxies due to its sole dependence on the mass distribution of the lens galaxy. Over the
past decade, machine learning has been coupled with this in an attempt to establish a pipeline for extracting substructure information from lensing images in anticipation of the next generation of wide surveys such as Euclid and LSST. As of yet, however, the
required accuracy has yet to be obtained, highlighting a need for more advanced machine learning architectures and techniques. In this talk, I will present a data augmentation technique that boosts network performance without the need for higher resolution
observations or more complex machine learning architectures.</span><span style="font-size:14.0pt;font-family:"Aptos",sans-serif;color:black;mso-fareast-language:EN-US"><o:p></o:p></span></p>
