Eight low-redshift Little Red Dots identified in DESI DR1 exhibit broad Balmer lines, steep decrements, compact shapes, and negligible variability, with a number density roughly 10,000 times lower than at z>4.
New automated software detects quasi-periodic microstructures in pulsar emissions, reports first detections in three pulsars, and confirms their periods scale linearly with pulsar rotation period.
The [CII]-to-molecular gas conversion factor evolves from over 10,000 to about 10 solar masses per solar luminosity as galaxies enrich from very low metallicity at high redshift to higher values later, making a redshift-independent factor unusable.
N-body and SPH simulations show that gas accretion along a galactic warp can generate global, long-lived phase spirals in the stellar disc with amplitudes comparable to those observed by Gaia.
JWST transit observations refine ephemerides of TOI 700 d and e by an order of magnitude in period precision but yield only upper limits on exomoons larger than Ganymede due to 46 ppm correlated noise attributed to stellar granulation.
Speckle imaging of 81 RR Lyrae stars detects 10 likely bound companions at 20-220 AU separations, yielding a binary fraction estimate above 12 percent.
Sub-arcsecond LOFAR imaging at 145 MHz resolves the acceleration site and downstream structure of a high-redshift radio relic, confirming its diffuse nature, showing log-normal magnetic field profiles, and providing hints of redshift evolution in the radio power versus cluster mass correlation.

Stellar mass functions in the peaks of the Hyperion protostructure at z~2.5 show a mass-dependent excess relative to the field, with ~10x enhancement at log(M*/M⊙)~11 versus ~3.5x at log(M*/M⊙)~9.5.
SDSS-WISE coordinate offsets plus red WISE colors pre-select advanced mergers likely to host unresolved dual-AGN candidates, with Keck AO confirming substructure in 20 of 46 targets at 43 percent yield.
Simulations reveal that two-parameter extinction PDFs fit SN Ia data better than the exponential, implying intrinsically redder supernovae by about 2 sigma.
New envelope binding energies derived from PARSEC stellar tracks alter compact binary merger rate densities by over an order of magnitude when used in population synthesis.
The HRIEUV PSF at 174 Å redistributes 57% of light via diffraction (26%) and scattering (42%), and deconvolution with it boosts bright structure intensities by up to 40% while reducing dark areas by up to 85%.
Cryogenic phased array feed achieves 21-25 K system temperature over efficiency and 3D SVD noise reduction improves compact and extended HI source detection over traditional 2D methods.
A new deep-to-wide transfer function reduces mean redshift biases in Euclid tomographic bins by matching reference sample color distributions to the wide survey.
Random forest models using early magnitudes, time differences, and new magnitude rates identify up to 13.6% of true broad-lined Ic supernovae in unseen test data.
Extended-image strong lensing model of cluster G165 reduces mass-parameter uncertainties by over an order of magnitude and maps dust extinction in the host of SN H0pe at z=1.78, finding A_V ≈ 0.9 mag near the explosion site.
A method using Balrog synthetic injections corrects spatially variable detection and classification rates in DES Y3 data, reducing relative detection rate standard deviation by a factor of five and lowering bias in stellar stream density power spectra.
GravSphere2 extends Jeans modeling to fourth order with LOS and PM data plus flexible anisotropy forms to recover mass density, anisotropy, and density slope in spherical stellar systems while breaking the mass-anisotropy degeneracy.
DES supernova data alone give Omega_M = 0.352 +/- 0.017 in flat LambdaCDM and confirm acceleration at >5 sigma, with dark energy consistent with a cosmological constant to within ~2 sigma when combined with other probes.
High-resolution spectroscopy of 51 Peg b confirms atmospheric H2O, constrains high metallicity and solar C/O via Bayesian retrieval, and yields an alternative orbital semi-amplitude of 102.8 km/s with revised mass 0.61 MJup and inclination 49.8 deg.
A self-consistent model of cosmic ray transport in molecular clouds with ballistic, diffusive, and hybrid scenarios applied to Taurus shows enhanced scattering on clump scales, suppressed diffusion coefficients, and elevated ionization rates.
Low-energy PISNe from 140 solar-mass Pop III stars produce second-generation stars at median [Fe/H] ~ -5.5 with odd-even patterns, but their absence from EMP observations disfavors PISNe as the main early enrichment channel.
