abstract

A study of the group properties of galaxies in our immediate neighborhood provides a singular opportunity to observationally constrain the halo mass function, a fundamental characterization of galaxy formation. Detailed studies of individual groups have provided the coefficients of scaling relations between a proxy for the virial radius, velocity dispersion, and mass that usefully allows groups to be defined over the range $10^{10} - 10^{15}$ $M_\odot$. At a second hierarchical level, associations are defined as regions around collapsed halos extending to the zero velocity surface at the decoupling from cosmic expansion. The most remarkable result of the study emerges from the construction of the halo mass function from the sample. At $\sim10^{12}$ $M_\odot$ there is a jog from the expectation Sheth-Tormen function, such that halo counts drop by a factor $\sim 3$ in all lower mass bins.

Cosmic web stripping and starvation of low-mass filament galaxies in TNG50

astro-ph.GA · 2026-05-22 · unverdicted · novelty 5.0

Low-mass filament galaxies in TNG50 exhibit smaller asymmetric cold gas discs due to cosmic web tidal fields causing altered accretion or starvation and late-time stripping, while integrated stellar and halo properties remain similar to field counterparts after mass and environment controls.

Resolved HI and Environmental Dynamics

astro-ph.GA · 2026-07-02 · unverdicted · novelty 2.0

SKA-mid AA4 will enable deep, spatially resolved HI imaging over hundreds of square degrees at column densities down to 10^18 cm^{-2} to study environmental gas processes from isolated galaxies to clusters.

  • Exploring the synergies of $[\mathrm{O\,II}]\lambda 3727$ with MUSE spectroscopy in PHANGS H II regions astro-ph.GA · 2026-07-01 · unverdicted · none · ref 129 · internal anchor

    Combining [O II] doublet data with MUSE spectra creates a homogeneous H II region catalog and compares strong-line metallicity calibrations, showing low scatter in radial gradients and [S III]/[S II] as a robust ionization parameter tracer.
