<p class="xmsonormal"><span style="font-size:12.0pt;font-family:"Aptos",sans-serif;color:black">The fourth observing run of the LIGO-Virgo-KAGRA detector network is ongoing, and the number of detections of gravitational waves from binary black hole mergers
is rapidly reaching into the hundreds. Yet despite this wealth of detections, it is still unclear how black holes become bound into tight binaries that merge within the age of the Universe.
<o:p></o:p></span></p>

<p class="xmsonormal"><span style="font-size:12.0pt;font-family:"Aptos",sans-serif;color:black">Binaries that form and merge in isolation may have different parameters than those that form under via dynamical interactions. The masses and spins of binaries
have typically been touted as keys to deciphering formation channels; however, these parameters have significant drawbacks as formation-channel indicators.<o:p></o:p></span></p>
<p class="xmsonormal"><span style="font-size:12.0pt;font-family:"Aptos",sans-serif;color:black"><o:p> </o:p></span></p>
<p class="xmsonormal"><span style="font-size:12.0pt;font-family:"Aptos",sans-serif;color:black">The most robust indication of dynamical evolution is orbital eccentricity: isolated binaries will have essentially circular orbits at detection, while a fraction
of dynamically-formed binaries will have measurable eccentricity. Gravitational waves from eccentric binaries are challenging to detect and analyse, yet in the last few years, a handful gravitational-wave events have been shown to contain tantalising hints
of orbital eccentricity.<o:p></o:p></span></p>
<p class="xmsonormal"><span style="font-size:12.0pt;font-family:"Aptos",sans-serif;color:black"><o:p> </o:p></span></p>
<p class="xmsonormal"><span style="font-size:12.0pt;font-family:"Aptos",sans-serif;color:black">Additionally, future gravitational-wave detectors will be sensitive to smaller binary eccentricities and earlier binary evolutionary epochs, enabling us to dive
deeper into their formation stories.<o:p></o:p></span></p>
<p class="xmsonormal"><span style="font-size:12.0pt;font-family:"Aptos",sans-serif;color:black"><o:p> </o:p></span></p>
<p class="xmsonormal"><span style="font-size:12.0pt;font-family:"Aptos",sans-serif;color:black">In this talk, I will demonstrate how eccentricity may be detected and leveraged to reveal details of a binary’s history. I will show how signals from eccentric binaries
enable us to uncover external influences to their evolution, including perturbing tertiaries and circumbinary disks, with current and future detectors. I will review what we can learn about our population of binary black holes when we combine observations
of their masses, spins, and eccentricity. I will also demonstrate how studying these parameters simultaneously reveals the formation scenarios of compact binaries.<o:p></o:p></span></p>

<p class="MsoNormal" style="background:white"><span style="color:black">Active galactic nuclei (AGN) play a crucial role in the evolution of massive galaxies, and their fueling and feedback efficiency depend on the environment. In this talk, I will present
a study of the orientations of AGN jets and their optical counterpart in relation to the cosmic web environment. Using LOFAR Two-metre Sky Survey (LoTSS), DESI Legacy Imaging Surveys, and the SDSS cosmic filament catalogue, we find that galaxy optical major
axes tend to align with cosmic filaments, suggesting the growth of galaxies through mergers along filaments. On the other hand, AGN jets, typically perpendicular to the host galaxy’s major axis, show more randomized orientations in cosmic filament environments.
This supports a scenario where black holes in filaments experience chaotic accretion as a result of numerous galaxy mergers. I will discuss the implications of these results in terms of the large-scale alignment of radio jets, intrinsic alignment of galaxies,
and anisotropic quenching of satellite galaxies. Our results highlight the role of cosmic filaments in shaping AGN feedback and galaxy evolution.<o:p></o:p></span></p>

<p class="MsoNormal" style="background:white"><span style="color:black">Intracluster light (ICL) has been proposed as a luminous tracer of dark matter (DM) in galaxy clusters, as these stars are not bound to any particular galaxy but are instead governed by
the cluster’s gravitational potential. It has been found that the isophotal contours closely follow the mass distribution of clusters out to ~200kpc observationally and in simulations (Montes and Trujillo 2019, Alonso Asensio et al. 2020). In this talk, I
will present a shape analysis of ICL and DM from the Hydrangea and Horizon-AGN simulations. The elliptical shapes and orientations of these components are calculated using the moment of inertia tensor, extending to radii of ~1Mpc, both in 2D projections and
3D. I will also explore how cluster properties, specifically halo mass and formation redshift, affect the shapes of ICL and DM.<o:p></o:p></span></p>
