Large language model (LLM) platforms introducing advertising must decide how much capability ad revenue should fund and what consumers should pay to avoid ads. We study a monopolistic platform that jointly chooses costly response quality, advertising intensity...

Modern language models rely on subwording tokenization to define the discrete units of input processing, typically using methods like Byte Pair Encoding (BPE) that treat whitespace as a fixed semantic boundary. This design is inherently limited, as many meanin...

Understanding the evolution of solids in protoplanetary discs is important to comprehend the formation of giant planets cores and terrestrial planets. The ALMA Large Program AGE-PRO studied key disc properties in a survey of 30 protoplanetary discs across thre...

Higher-order statistics are becoming increasingly useful in clustering studies of the large-scale structure (LSS) of the universe. The kNN-CDFs are one such higher-order statistic, sensitive to all N-point correlations and easy to compute on data. Utilising th...

Atmospheric escape shapes close-in planets mostly in their first tens of Myr. The young V1298Tau system (10-30Myr) is a benchmark for investigating photoevaporation and planetary evolution at early stages. The metastable HeI near-infrared triplet is a key prox...

AI weather models perform competitively with traditional physics-based models at a fraction of the computational cost, and they are thus already used operationally. However, studies reach conflicting conclusions about their ability to forecast extreme weather...

Constraining atmospheric loss is crucial for understanding the evolution of planetary atmospheres. We report the detection of an evaporating exosphere from TOI-3884b, a super-Neptune in a polar orbit around an M4 dwarf star. We infer this evaporation from a 6....

Scattering patterns encode the structure of extended objects, as demonstrated by charged particle scattering on atomic nuclei. Gravitational wave (GW) diffraction offers an analogous probe of otherwise invisible mass distributions. At linear order in the lens...

The Hubble tension motivates direct tests of the internal consistency of the local distance ladder. We perform forward and backward consistency checks between Type Ia supernovae in Cepheid host galaxies and the Hubble-flow supernova sample using Pantheon+ data...

A detection of primordial $B$ modes in the Cosmic Microwave Background (CMB) polarisation relies on a robust control and removal of contamination from astrophysical polarised foreground emission. We examine how much polarised extragalactic point sources may co...
