- background provide an internal consistency test of GR through independent waveform reconstruction and binary parameter estimation. Future work could extend the LILA selection function presented in this paper to make astrophysical predictions, such as expected LILA detection rates and redshift evolution of black hole merger rates, using semi-analytical models (e.g., Volonteri et al. 2008; Barausse 2012; Pacucci & Ferrara 2015; Valiante et al. 2018; Dayal et al. 2019; Sassano et al. 2021; Trinca et al. 2023;

SOFIA observations provide the first experimental magnetic-dipole hyperfine constants for [13C II] and refined centroid frequency using astronomical data.
TopoFisher optimizes trainable filtrations, vectorizations, and compressors in persistent homology to maximize Fisher information, yielding higher information than fixed cosmological summaries and approaching neural baselines with far fewer parameters while generalizing better under simulator shifts
JWST nebular spectra detect cooling ~400 K carbonaceous dust emission in normal SN Ia 2023qov at +276 and +363 days, modeled as pre-existing circumstellar dust with mass ~10^{-4} M_sun located within ~1 light year.
Dust grain size distributions evolve from large-grain dominated at high redshift to MRN-like at low redshift, driven primarily by shattering and ISM accretion after stars supply initial large grains, reproducing z=0 dust masses and Milky Way extinction properties.
Two young low-mass stars show solar C/O ratios while their inner disks are hydrocarbon-rich with C/O greater than one, providing direct evidence that disk processes enhance inner-disk carbon.
Sweeping secular resonance from an intermediate-mass companion and depleting disk enhances AGN TDE rates to 10^{-3}-10^{-2} per galaxy per year on Myr timescales.

An MHD-informed model with self-consistent radial profiles applied to ten z >= 2.5 quasar jets yields higher jet powers than one-zone models, favors electron distributions tied to gas pressure, and finds low magnetization with no clear redshift trend in Lorentz factor.
GraphNPE recovers a significantly lower central density for Boötes I consistent with a core while Draco remains marginally cuspy, and demonstrates that higher-order velocity moments reduce bias in dynamical modeling.
Defines a sample of ~1300 SDSS quasars as Local Red Dots matching LRD photometric colors at z~0.4-0.8, with a V-shaped subset showing Balmer absorption and [NeV] emission, and SEDs modeled as reddened AGN plus host galaxy that match LRD stacks.
