At fixed stellar mass, inner gas mass—not size, SFR, or potential—best predicts gas metallicity, and differences in long-term inflow histories can explain the pattern.
Void galaxies identified by local volume in non-spherical voids are bluer and more star-forming than non-void galaxies, with the environmental effect decreasing with stellar mass.
Binary fractions in elliptical galaxies remain approximately flat with radius once stellar population variations are subtracted, showing less than 5% change at one effective radius for nearly all galaxies studied.
Observational study finds spiral structure correlates with steeper metallicity gradients, larger bulges with shallower gradients and higher metallicities, but no gradient differences from bars or spiral winding tightness.
A prototype photonic ring resonator device was characterized in the upper H-band, with a quadratic model for suppressed-wavelength progression found to be more consistent with data than a linear model, though depth and FWHM trends remain unresolved.
Multi-wavelength observations of 4C+29.30 show a misaligned biconical ionized outflow and localized jet-ISM interactions, providing evidence for simultaneous radiative and mechanical AGN feedback.
Overview of HI modeling methods finds consistency in cosmic HI density but systematic differences in HI-halo mass relation shape and redshift evolution.
