Detection of helium lines in Balmer-dominated shocks of Type Ia SNRs reveals enhanced helium in some remnants and challenges shock models, enabling new constraints on progenitor environments.
An accelerating plasma blob crossing the BLR in 3C 279 reproduces the 2013 orphan gamma-ray flare's hard spectrum, rapid rise, slow decay, and lack of optical variability via varying external Compton scattering.
A new catalogue of bar lengths and widths from HST images of 8230 galaxies shows bars are about 13% weaker at higher redshift, with longer bars in higher-mass quiescent galaxies and trends consistent with slow quenching.
In the IllustrisTNG model, CGM gas around z=1 galaxies mixes quickly and separates into cold inner and warm-hot outer phases within 500 Myr due to feedback, with kinematic decorrelation over 400 Myr and ion-specific phases lasting different durations.
IY Lyr is a thick-disk RRc star with a 1.37 solar-mass companion most likely a neutron star in a 3.94-year eccentric orbit, confirmed by photometry, spectroscopy, and astrometry.
Spatially resolved observations of z~0.1 galaxies show Mg II absorption outflow velocities are systematically higher than Hα emission velocities by ~0.4 dex while maintaining similar correlations with star formation rate and surface density.
A model based on Chandrasekhar's 1951 time-invariant quantity quantitatively explains the Mach-number dependence of the density power spectrum slope in isothermal supersonic turbulence and demonstrates that the slope cannot reliably determine the Mach number.
Low-luminosity AGN exhibit optical variability structure function slopes that increase with black hole mass from ~0.1 to ~0.3, with amplitude anticorrelated with luminosity, no breaks observed, and variability continuing to rise on 20-year timescales.
Detection of a persistent ~433-day optical QPO in blazar 3C 454.3 at 2.53σ significance using Lomb-Scargle, WWZ, and PDM methods, with a new test for seasonal gaps.
Only the simultaneous presence of AGN jets and winds produces sufficient turbulence via their interaction to suppress star formation in elliptical galaxies; neither component alone is effective.
In TNG-50, 80% of Milky Way-mass galaxies align their present-day angular momentum with the orbital angular momentum of their most massive merger, and 81% of their stellar halos rotate prograde relative to the disk.
Spectral fits to magnetar burst X-rays disfavor light ions and favor effective charge Z~37, providing evidence for heavy nuclei from the neutron star crust.
LHAASO gamma-ray data from G150.3+4.5 and γ-Cygni show high-energy components produced by PeV cosmic rays from supernova remnants colliding with molecular clouds.
Galaxy clusters have an average projected ellipticity of 0.310 with axis ratio 0.527, showing no significant mass or redshift dependence, measured via weak lensing on DES Y3 data and verified with mocks.
VLA L-band polarization observations of SNR G7.7-3.7 show cocoon morphology from interaction with pre-existing circumstellar shells, with magnetic fields compressed along filaments and RM variations tracing massive progenitor winds.
Restricting analysis to the top 1% most luminous galaxies in GW localization volumes yields 1-4 candidate hosts for three specific events, with 29-36% probability of random association.
Pulsar radio emission beams from the two poles are generally dissimilar in azimuth width and often radius, based on rotating vector model fits to polarization data from eight double-pole interpulse pulsars.
An optimal Stokes number window of 0.01-0.03 allows streaming instability to form planetesimals and pebble accretion to build all three main planet classes, with cold gas giants needing the lowest turbulence and largest discs.
Multi-epoch spectroscopy of UNAM-KIAS 613 shows transient double-peaked broad Hα emission interpreted as a one-time bipolar outflow in an isolated low-luminosity AGN with Eddington ratio ~0.03-0.04.
Comparative analysis reveals a potential separate population of ULXs in spiral galaxies with single occurrences, featuring both soft and hard sources, while highlighting globular cluster links in elliptical galaxies.
Early kinematically persistent planes of satellite galaxies are fossil remnants of high-redshift anisotropic mass collapse along the principal directions of the local cosmic web during the fast assembly phase of host halos.
Jet and wind feedback from AGN couple nonlinearly through Kelvin-Helmholtz instability, raising energy dissipation efficiency to 0.64 and dropping star formation rate to 10^{-3} solar masses per year.
Multiwavelength study of 621 winged radio galaxies shows XRGs are radio-luminous with frequent backflow signatures while ZRGs link to lower jet power and environmental perturbations.
