(up to the leading nonlinear order) complex field theory. This theory reveals a close similarity to the integrable complex sine-Gordon model which possesses exact multi-Q-balls. We show that the excited oscillons, with characteristic modulations of their amplitude,
are two-oscillons bound states generated from a two Q-ball solution.<o:p></o:p></span></p>

summary of previous supernova surveys and the use of Type Ia supernovae in cosmology. I will then focus on the expected advances enabled by the Time Domain Extragalactic Survey (TiDES) which will use the 4MOST instrument to obtain spectra tens of thousands
of supernovae and their host galaxies discovered by the Rubin Observatory's Legacy Survey of Space and Time (LSST). I will also describe some early results and prospects for supernova science with the Euclid mission, and discuss how the combination of Rubin/LSST,
TiDES and Euclid will advance supernova cosmology.<o:p></o:p></span></p>

<p class="xmsonormal"><span style="font-size:12.0pt;font-family:"Aptos",sans-serif;color:black">Semi Analytic Models (SAMs) provide a rich testbed for a wide variety of different astrophysical theories. The ability for SAMs to produce large galaxy catalogues
within reasonable timeframes, even on moderate hardware, enables rapid refinement of novel galaxy evolution models as well as the ability to quickly produce companion mock surveys matching the parameters of new observations. However, SAMs still suffer the
same problem much of astronomy is encumbered by: too much data and too little manpower to process it. The requirement for SAMs to be performant (often being programmed in immensely optimized C, C++ or FORTRAN code) inhibit the speed at which an experienced
user can make additions and often prevents any users without a strong technical background from using them at all. This issue is accentuated in the era of JWST, where quickly reevaluating our models of galaxy formation in response to unprecedented observations
is crucial. I present "Jalaxies", a project that aims to fully decouple the highly optimized core code required by a typical SAM from the actual descriptions of the analytic mechanisms. Jalaxies takes simple pythonic-esque descriptions for each mechanism
in a target SAM and produces a fully self-contained, stack optimized, and highly parallel Rust binary. The easy and intuitive adjustments to models that Jalaxies allows, along with support for: both a GUI and a terminal interface, on the fly cosmology rescaling,
easily transferable JSON descriptions of the SAM, simple IO optimized tree files, various output types such as lightcones and galaxy trees, and the ability to output directly into numpy compatible file formats, means even the most technophobic astronomer
can produce science with Jalaxies the very same day it was downloaded.<o:p></o:p></span></p>
