Deep interferometric observations of a z≈1.12 barred spiral reveal bar-driven molecular inflows at a rate matching the galaxy's star formation rate of ~36 M⊙/yr.
SchwarMAX delivers a fast GPU-native Schwarzschild modeling code that recovers density profiles and bar pattern speed from mock IFU data of a simulated barred galaxy.
Improved pPXF uses analytic Fourier transforms of Gauss-Hermite functions for accurate convolution, providing reliable velocities even when σ is much less than the sampling ΔV.
ATTILA tool identifies 24 new ultra-diffuse galaxies in Hydra I, doubling the known population to 48, plus 92 additional low surface brightness galaxies, while recovering over 80% of previously known ones.
NGC 4264 hosts a fast bar with rotation rate R_cor/a_bar = 0.88 measured via the Tremaine-Weinberg method on MUSE data, indicating internal formation despite ongoing weak interaction.
