Does a Second-Class Primary Constraint Generate a Gauge Transformation? Electromagnetisms and Gravities, Massless and Massive

J. Brian Pitts

In constrained Hamiltonian dynamics there are two views regarding how first-class constraints generate gauge transformations: individually or only in a certain combination, the Ros…

Geospatial embeddings detect old-growth forests but buffered spatial validation narrows their advantage over Sentinel features

Thomas Ratsakatika, Mihai Zotta, Srinivasan Keshav +1

Old-growth forests develop over centuries under minimal anthropogenic disturbance, producing structurally complex and biodiverse stands. In Europe, protecting them requires mapping…

Probing Exoplanetary Chemistry with Ariel: Scientific Priorities and Observational Strategies

Olivia Venot, Yamila Miguel, Robin Baeyens +30

Over the past two decades, increasingly precise observations have revealed that exoplanet atmospheres are chemically diverse and often far from equilibrium, with processes such as…

The relationship between morphology, density, and location in the cosmic web from massive to dwarf galaxies

Ilin Lazar, Sugata Kaviraj, Aaron E. Watkins +5

We study how morphology relates to environment from massive to dwarf galaxies using, for the first time, a mass-complete sample of ~13,000 galaxies, in the stellar-mass and redshif…

Effective Ionic Valence and Local Magnetic Moment in Kagome Superconductors

Ruoshi Jiang, Zi-Jian Lang, Yuzki Oey +11

In order to understand the unexpected similarity and the correlated behavior in kagome superconductor families AVSb (A = K, Rb, Cs) and ATiBi (A = Rb, Cs), we inves…

Orukeet: Multilingual ASR with Frozen Gabor Kernels

Nathan Roll, Irene Yi, Büşra Marşan +6

Orukeet replaces half of an adapted Parakeet encoder's temporal filters with 12,288 fitted Gabor kernels, freezes these replacements, and trains the remaining parameters on multili…

A Dusty Quenching-candidate AGN host at z=5.7: massive quiescent galaxies may quench already during the dust-obscured phase

Francesco D'Eugenio, Matilde Brazzini, Roberto Maiolino +12

We present a spectro-photometric analysis of RUBIES-EGS-9809, a broad-line AGN host at z=5.7 with a Balmer break and a dominant point source. The source is dust reddened (3 m…

Gravitational instability in planet-forming discs

Cristiano Longarini, Giuseppe Lodato

During the earliest phases of star and planet formation, a young star is surrounded by a disc that can become gravitationally unstable. Indeed, if the protoplanetary disc is suffic…

Euclid preparation. The shape of halo profiles in CDM and non-standard cosmologies

Euclid Collaboration, L. Pizzuti, G. Y. Ferron +304

We study the shape of three-dimensional and projected dark-matter halo profiles extracted from cosmological -body simulations in CDM and non-standard cosmologies, using the \…

Earth observation embeddings are effective sub-grid descriptors for probabilistic weather downscaling

Pedro Sousa, Will Tebbutt, Sadiq Jaffer +3

Global weather reanalyses and forecasts resolve the evolving atmospheric state on coarse grids, but site-specific applications require predictions at arbitrary locations where near…

Unease, Ambivalence, and Endured Disloyalty in Japanese Consumer Experiences with Dark Commercial Patterns

Katie Seaborn, Jo Yukami, Tatsuya Itagaki +7

Dark commercial patterns and deceptive user interface (UI) designs (or DPs) trick consumers into actions that benefit the shareholders. The legal and ethical implications of DPs ar…

Agentic research is oxymoronic

Natalie B. Hogg

The use of agentic large language models obviates human interpretation of scientific results, and will lead to substantial distrust in the literature.
