Agent learning is shifting from learning from human data toward learning through interaction with the world. However, scaling such learning directly in real-world computer systems is challenging and can introduce substantial security risks. We therefore propos...

Context compression improves long-context efficiency but may introduce faithfulness issues through an information bottleneck. Existing evaluations rely on QA metrics, but a reader can still answer correctly from an unfaithful compression, so these metrics unde...

Cosmic filaments connect the nodes of the large-scale web and are thought to harbour a substantial fraction of the low-z baryon budget, yet a physically motivated framework for organising their diverse gas properties has been lacking. Here we show that the lin...

We investigate the impact of turbulence and magnetic field on the formation of unipolar outflows in the gravitational collapse of isolated low-mass cloud cores using three-dimensional non-ideal magnetohydrodynamics simulations. In the models explored in this s...

We revisit a late-time, model-independent distance-consistency framework that combines strong gravitational lensing systems (SGLS), ultraviolet/X-ray quasars (QSOs), and 38 Sunyaev--Zel'dovich/X-ray galaxy-cluster angular-diameter distances. The analysis focus...

Gravitational lensing can split the signal of a binary merger into two images, which either overlap and interfere or arrive as separate events. We show that the matched-filter output of every two-image template can be straightforwardly constructed from the sig...

We report a transiting sub-Neptune candidate with a period of 36.34 days around TIC 402710280 (TYC 9041-03677-1), a K dwarf of TESS magnitude 9.24 at 66.8 pc that the Transiting Exoplanet Survey Satellite (TESS) has observed only in full-frame images. Four tra...

In this note, we introduce the Hubble susceptibility of cosmological-collider masses, encoded in the scale dependence of the squeezed-limit oscillation. Heavy fields generically receive Hubble-induced mass corrections during inflation, and we show that the loc...

Space-borne gravitational wave (GW) detectors such as TianQin are expected to detect GW standard sirens for cosmological parameter estimation. All previous studies of TianQin adopted the $Λ$CDM model to generate mock standard siren data. In this work, we quant...

The validity of linear perturbation theory and the role of backreaction in single-field inflationary models that enhance power at small scales have recently been under debate. We investigate scalar backreaction semi-analytically in a mean-field approach within...

We present an updated analysis of non-standard neutrino self-interactions, where the interaction is effectively mediated by a heavy particle, using the latest available data from DESI and the CMB. The considered data include combinations of DESI DR1 full-shape...

Cosmological analyses of Stage-IV galaxy surveys require large ensembles of lightcone mock catalogues, but a full survey-scale $N$-body run costs of order $10^7$ CPU hours, putting such ensembles out of reach. We present a framework that produces survey-scale...
