Kavli Affiliate: Nickolay Gnedin | Summary:The "Reduced Speed of Light" (RSL) approximation is commonly used to speed up radiative transfer calculations in cosmological simulations. However, it has been shown previously that the RSL approximation leads to photon non-conservation when the radiation field is rapidly evolving in time. I show that these missing photons can be […]
Kavli Affiliate: Michael Gladders | Summary:We present NIRSpec/IFS observations of a rest-frame UV-bright, massive ($M_* sim 10^10$ M$_odot$, $z_AB=20.5$) galaxy highly magnified by gravitational-lensing observed just after the end of the epoch of reionization ($z=5.04$, $barĪ¼sim90$). With JWST accessing the restframe UV and optical spectrum of this galaxy with high fidelity, we classify this UV-bright […]
Kavli Affiliate: Katrin Heitmann | Summary:Self-consistently modeling baryonic effects in survey-scale cosmological simulations has become increasingly important as the diversity, precision, and statistical reach of modern observations continue to improve. The advent of exascale computing now enables a new generation of simulations that couple these physical processes across full-sky volumes with excellent statistical sampling of […]
Kavli Affiliate: David W. Miller | Summary:Over the last four decades, the way knowledge is created in academia has transformed dramatically: research teams have grown larger, scholars draw from ever-wider pools of prior work, and the most influential discoveries increasingly emerge from complex collaborative efforts. Using a massive dataset of over 15 million publications spanning […]
Kavli Affiliate: Michael Turner| First 5 Authors: Brad Shook, Brad Shook, , , | Summary:Time series foundation models (TSFMs) pretrained on data from multiple domains have shown strong performance on diverse modeling tasks. Various efforts have been made to develop foundation models specific to electroencephalography (EEG) data, which records brain electrical activity as time series. […]

Kavli Affiliate: Wayne Hu| First 5 Authors: Peiyu Hu, Peiyu Hu, , , | Summary:Cross-domain recommendation (CDR) is crucial for improving recommendation accuracy and generalization, yet traditional methods are often hindered by the reliance on shared user/item IDs, which are unavailable in most real-world scenarios. Consequently, many efforts have focused on learning disentangled representations through […]
Kavli Affiliate: Andrey Kravtsov | Summary:We present model calculations of the reionization history of hydrogen using star formation histories, computed with a galaxy formation model which reproduces properties of local dwarf galaxies and UV luminosity functions of galaxies at $z=5-16$. We use the ionizing photon density functions predicted by the model along with different models […]
Kavli Affiliate: David W. Miller | Summary:We discuss a phenomenological model extending the minimal supersymmetric standard model containing axions and their supersymmetric partner, the axino. In the supersymmetric DFSZ axion model, the axino has tree level couplings to the higgs sector. In the case where R-parity is conserved, collider experiments may be sensitive to displaced […]
