Severe gas expulsion and expansion in a primordial star cluster, combined with a top-heavy IMF, can reproduce the high velocity dispersion and broad stream of C-19 without dark matter subhalos.
First detection of mHz QPOs in 1A 0535+262 below 27 keV with frequencies evolving from 41 to 93 mHz, mostly hard lags, and double-peaked high-energy structure near outburst peak, interpreted as linked to soft-photon source and Comptonizing outflow evolution.
Resolved gas and dust maps in a z=2 quiescent galaxy reveal accreted material from tidal interactions and a past star-formation rejuvenation, indicating that gas content variations are not solely due to consumption timescales.
Exhaustive symbolic regression identifies low-complexity functional forms for luminosity and mass functions that outperform Schechter and Press-Schechter parametrizations while satisfying physical extrapolation and integration constraints.
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.
Accreting X-ray sources cannot supply enough EUV photons to account for He III regions in metal-poor star-forming dwarf galaxies.
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.
A Monte Carlo model of a Kerr black hole corona shows that photon collisions create a dense electron-positron pair cloud concentrated near the black hole, yielding X-ray temperatures, Compton parameters, and 4-10% polarization consistent with binary black hole observations.
The Milky Way stellar disk shows a broken radial density profile with four components, azimuthal dependence, inner and outer flaring, and a density-metallicity bump possibly from radial migration.
Derives and validates via PIC simulations a scaling law for nonthermal spectral tails in mildly to strongly magnetized turbulent plasmas, with application to black-hole coronae.
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.
PSR J2101-4802 is a transitional millisecond pulsar with a ~1-day orbit, 0.15 solar mass He-WD companion, and large orbital period derivative that links redback-like systems to detached binaries.
Disk formation simulations reproduce carbonaceous chondrule oxygen isotopes with moderate radial infall or ice-depleted parental clouds, but ordinary chondrules inside the snow line remain difficult to explain under the modeled conditions.
XRISM data show a ~2 keV cooler gas phase with 300-400 km/s dispersion and bulk motion in the central Perseus cluster, distinct from the single-temperature gas beyond 60 kpc.
Simulations show LIFE could use 25-80 m baselines or discrete values with under 10% loss in planet yield and fringe tracking.
Radiation-hydrodynamic simulations of subcritical X-ray pulsars find resonant Compton scattering governs plasma deceleration, vacuum polarization dominates birefringence to enhance cyclotron features, and cyclotron energy rises with accretion luminosity.
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.
Multi-technique timing analysis indicates a ~478-day QPO in the gamma-ray emission of BL Lac GB6 J1037+5711.
N-body simulations show massive stars in TCCA clusters rapidly acquire triple or higher multiples and local density enhancements via dynamics, with multiplicity trends and shallower N_* profiles than competitive accretion models, matching AFGL 5180 better.
Comparisons of three cosmological simulations show HI-rich failed halos occupy different mass regimes and predict that more can be discovered locally in HI-poor environments rather than at high redshift.
GAMA 376183 is a rare Eddington-limited heavily obscured AGN in a merging low-mass galaxy, triggered by the merger and identified via strong [Ne V] emission.
