This week, our seminar speaker is Dr. Elisabeth Sola (Cambridge). Elisabeth will be visiting Nottingham from Wednesday - Friday, so there should be plenty of time to speak with her while she is here. Elisabeth will be arriving around noon on Wednesday,
so there will be lunch with the seminar speaker this week. If you would like to join us for lunch (we can subsidize a few students to join), please let us know by tomorrow evening. The schedule of events on Wednesday is:</div>

Abstract:</div>
<p class="elementToProof" style="text-align: left; text-indent: 0px; background-color: white; margin: 0cm;">
<span style="font-family: Aptos, sans-serif; font-size: 12pt; color: black;">Hierarchical models of galaxy formation predict that galaxies grow through successive mergers, leaving behind tidal features—faint stellar structures that preserve a record of recent
mass assembly. The properties of these features depend on the nature of the mergers that produced them, making them key tracers of galaxy evolution. However, their intrinsically low surface brightness (LSB) poses a major observational challenge, requiring
tailored observing strategies and data processing techniques.</span></p>
<p class="elementToProof" style="text-align: left; text-indent: 0px; background-color: white; margin: 0cm;">
<span style="font-family: Aptos, sans-serif; font-size: 12pt; color: black;">In this talk, I will present a quantitative study of tidal features around hundreds of nearby galaxies, based on deep imaging from both ground-based (CFHT) and space-based (Euclid)
telescopes. Using a dedicated annotation tool, we systematically characterised these features in terms of their photometric and geometric properties. I will explore the connections between the host galaxies and their tidal features, and discuss the insights
these structures offer into the late-stage assembly of galaxies. Finally, I will touch on how tidal features can be used to constrain the shapes of dark matter haloes.</span></p>
