<p class="MsoNormal" style="background:white"><span style="font-size:12.0pt;color:black">Different notions of time arise from different choices of observer. In cosmological settings, a particularly natural choice is the spacetime volume, which is conjugate
to the cosmological constant. This gives rise to unimodular time, deparametrizing the Wheeler–DeWitt equation into a Schrödinger-like evolution equation. I will first explain how this construction appears in arbitrary dimension, with particular emphasis on
the four-dimensional case.<o:p></o:p></span></p>

<p class="MsoNormal" style="background:white"><span style="font-size:12.0pt;color:black">As an explicit Holographic realisation, I will then focus on near-extremal black holes, whose low-energy throat dynamics is universally described by Jackiw–Teitelboim gravity.
In this setting, promoting the vacuum cosmological constant to a dynamical top-form degree of freedom provides a bulk clock in the Henneaux–Teitelboim sense. Holographically, this modifies the usual Schwarzian boundary dynamics by coupling it to an additional
U(1) phase mode, reproducing the universal low-energy structure familiar from complex SYK. Finally, I will show that the resulting boundary theory can be rewritten as a (0+1) dimensional observer action, making explicit the relation between the bulk volume
clock and its holographic boundary counterpart.<o:p></o:p></span></p>

<p class="xxmsonormal" style="margin:0cm"><span style="color:black">Exoplanet atmospheres are tracers of the formation and evolution pathways that sculpt planetary systems. Doppler spectroscopy using ground-based high-resolution spectrographs has emerged as
one of the most promising recent techniques to characterise the atmospheres of planets in physical regimes beyond the solar system. Recent studies of gas-giant exoplanets have yielded extraordinary precision on the thermal and chemical properties of their
atmospheres, providing insights into their extraordinary formation histories and climates. I will give an overview of the current state of the field of high-resolution spectroscopy for exoplanet atmospheres, introducing the fundamentals of the technique, and
covering the latest key developments and synergies with other popular techniques for exoplanet atmospheric characterisation. With this background, I will discuss some recent work on characterising the dayside atmospheres of hot to ultra-hot Jupiter exoplanets
in the near-infrared using VLT/CRIRES+ and Gemini/IGRINS. I will also discuss the near-future prospects for high-resolution spectroscopy in improving the detail and precision in our measurements of exoplanet atmospheres as we approach the next leap in planet
detection and characterisation this decade using PLATO and the Extremely Large Telescope.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:12.0pt;color:black">Quenching models for massive galaxies frequently invoke AGN feedback as a primary mechanism. However, the lack of evidence for excess AGN activity in recently quenched post-starburst galaxies (PSBs)
may suggest that AGN are not the dominant quenching mechanism, that AGN activity is short-lived and does not extend into the PSB phase, or that the AGN are heavily obscured. If obscured AGN are present in PSBs, they should still be detectable through hot-dust
emission in the infrared. In this talk, I present results on the mid-infrared emission of PSBs in the PRIMER-UDS field.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt;color:black"><br>
I will also present preliminary results on the environmental dependence of low-mass PSBs across the PRIMER fields, providing insight into their dominant quenching pathways, as well as evidence for a potentially distinct population of ultra-low-mass PSBs.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:12.0pt">In this talk, I will present our recent works on galaxy chemical evolution from the local Universe (SDSS-IV/MaNGA) to intermediate redshift (COSMOS-WALL/LEGA-C), aiming to understand the roles of feedback
and environment in shaping galaxy evolution. We reconstruct the star formation and chemical enrichment histories of galaxies in a self-consistent framework, and investigate how the interplay between gas accretion and outflows drives their evolution. In particular,
we will discuss the roles of feedback from active galactic nuclei and supernovae, as well as environmental processes in regulating these mechanisms. Finally, I will highlight how forthcoming spectroscopic surveys such as 4MOST and WEAVE will provide key data
to further test and extend these scenarios.</span><span style="font-size:12.0pt;mso-fareast-language:EN-GB"><o:p></o:p></span></p>
