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.
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.
A ~1 solar-mass main-sequence star with supersolar metallicity has been traced back to the galactic center as a hypervelocity star ejected by the Hills mechanism.
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.
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.
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.
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.
Simulations predict Roman will detect roughly 11,000 microlensing events including about 100 with isolated neutron star lenses, using a characteristic feature in log t_E versus log theta_E space for classification.
Strong blended Lyα absorbers cluster with Lyα emitting galaxies at z>3 within 300 kpc and 300 km/s, confirming they trace the circumgalactic medium interface.
Five O4 gravitational-wave events prefer dynamical cluster formation; typical recoil kicks eject remnants from globular clusters but allow possible retention in nuclear star clusters, disfavoring efficient hierarchical growth in globular clusters.
AGN activity correlates independently with bar strength and bulge prominence in z≤0.1 galaxies after controlling for mass and color.
Rotating stellar models initialized with observed velocity distributions yield modestly lower initial mass estimates for SN II progenitors than non-rotating models, with an upper limit of 20.4 solar masses.
Ground diode and on-sky calibration of QUIJOTE-TFGI confirms phase-switch errors near zero and yields Moon refraction index 1.209 at 31 GHz with consistent responsivity results.
Prospector is a flexible code for Bayesian inference of stellar population parameters from multi-wavelength photometry and spectroscopy via forward modeling and posterior sampling.
