Why Machine Learning Models Systematically Underestimate Extreme Values II: How to Fix It with LatentNN
Yuan-Sen Ting
Attenuation bias -- the systematic underestimation of regression coefficients due to measurement errors in input variables -- affects astronomical data-driven models. For linear re…
Evolving and interacting dark energy: photometric and spectroscopic synergy with DES Y3 and DESI DR2
M. Tsedrik, B. Bose
We investigate the Dark Scattering (DS) interacting dark energy scenario, characterised by pure momentum exchange between dark matter and dark energy, combined with a time-dependen…
Joint cosmological fits to DESI-DR1 full-shape clustering and weak gravitational lensing in configuration space
A. Semenaite, C. Blake, A. Porredon +69
We present a joint -pt cosmological analysis of auto- and cross-correlations between the Dark Energy Spectroscopic Instrument Data Release 1 (DESI-DR1) Bright Galaxy Surv…
Interpretable machine learning of halo gas density profiles: a sensitivity analysis of cosmological hydrodynamical simulations
Daniele Sorini, Sownak Bose, Mathilda Denison +1
Stellar and AGN-driven feedback processes affect the distribution of gas on a wide range of scales, from within galaxies well into the intergalactic medium. Yet, it remains unclear…
University of Hawaii 88-inch Telescope Observations of the Interstellar Comet 3I/ATLAS: Spectrophotometric Blue-Sensitive Spectral Time Series Spanning Two Months from Discovery
W. B. Hoogendam, D. Kuesters, B. J. Shappee +22
Interstellar objects are the ejected building blocks of other solar systems. As such, they enable the acquisition of otherwise inaccessible information about nascent extrasolar sys…
Viscously Spreading Accretion Disks around Black Holes: Implications for TDEs, LFBOTs and other Transients
Mila Winter-Granic, Eliot Quataert
We present a simple time-dependent model of viscously spreading accretion disks around black holes (BHs) with masses between . We apply the results to observations…
