A., Zohren, H., Collaboration, DES, Collaboration, SPT

Cosmic shear, galaxy clustering, and the abundance of massive halos each probe the large-scale structure of the universe in complementary ways. We present cosmological constraints from the joint analysis of the three probes, building on the latest an

New Ionization Models and the Shocking Nitrogen Excess at z > 5

Autor: Flury, Sophia R., Arellano-Córdova, Karla Z., Moran, Edward C., Einsig, Alaina

The new era of galaxy evolution studies hearkened in by JWST has led to the discovery of z > 5 galaxies exhibiting excess nitrogen with log(N/O)~1 dex or more than expected from log(N/O) vs 12+log(O/H) trends in the local Universe. A variety of novel

Isolated neutron stars as Science Validation for XMM2ATHENA: Ensuring robust data for future X-ray Astronomy

Autor: Pires, Adriana Mancini, Motch, Christian, Schwope, Axel, Traulsen, Iris, Ballet, Jean, Chakraborty, Sudip, Homan, David, Kurpas, Jan, Gomez-Moran, Ada Nebot, Pineau, Francois-Xavier, Tranin, Hugo, Webb, Natalie

The discovery of radio-quiet, X-ray thermally emitting isolated neutron stars (XINSs) in the ROSAT All-Sky Survey revealed a previously overlooked component of the neutron star population. Advancements in X-ray instrumentation and the availability of

Multi-Action Restless Bandits with Weakly Coupled Constraints: Simultaneous Learning and Control

Autor: Fu, Jing, Moran, Bill, Niño-Mora, José

We study a system with finitely many groups of multi-action bandit processes, each of which is a Markov decision process (MDP) with finite state and action spaces and potentially different transition matrices when taking different actions. The bandit

On the ERM Principle in Meta-Learning

Autor: Alon, Yannay, Hanneke, Steve, Moran, Shay, Shalit, Uri

Classic supervised learning involves algorithms trained on $n$ labeled examples to produce a hypothesis $h \in \mathcal{H}$ aimed at performing well on unseen examples. Meta-learning extends this by training across $n$ tasks, with $m$ examples per ta
