abstract

We investigate the baryonic Tully-Fisher relation in low surface brightness galaxies selected from the Arecibo Legacy Fast ALFA survey. We find that the $\rm HI$-bearing low surface brightness galaxies still follow the baryonic Tully-Fisher relation of typical late-type galaxies, with a slope of approximately 4 in the baryonic mass versus rotational velocity diagram on the logarithmic scale, i.e., $M_{\rm{b}}\propto v_{\rm{rot}}^4$. Our findings suggest that the matter distributions in low surface brightness galaxies may resemble that of general late-type galaxies, and hint that low surface brightness galaxies may not originate from dark matter halos of low densities or stronger/weaker feedback processes, but may emerge from dark matter halos with high spin values.

  1. Ultra Diffuse Dwarf Galaxies Hosting Pseudo-bulges

    astro-ph.GA 2024-12 conditional novelty 6.0 of 10

    Five ALFALFA ultra-diffuse galaxies host resolved central pseudo-bulges, and their HI-inferred rotation velocities are high relative to typical dwarfs of similar stellar mass.

  2. Halo Spin Dependence on Environment for HI-bearing galaxies

    astro-ph.GA 2024-11 conditional novelty 4.0 of 10

    A semi-analytic analysis of ALFALFA galaxies finds lower inferred halo spins in denser environments, but the estimator depends on HI mass, leaving the physical interpretation open.

  3. Moderate Influence of Halo Spin on Stellar Mass Distributions in Dwarf and Massive Galaxies

    astro-ph.GA 2024-11 conditional novelty 4.0 of 10

    An analysis of ALFALFA galaxies finds a weak to moderate inverse correlation between estimated halo spin and stellar surface density, with slopes consistent with zero at about 1 sigma.

  4. Strong Correlation between Galactic HI-to-stellar Mass Ratio And Halo Spin Explored by HI-rich Galaxies

    astro-ph.GA 2024-11 reject novelty 4.0 of 10

    Using a semi-analytic spin estimator, the authors claim halo spin strongly correlates with HI-to-stellar mass ratio in ALFALFA galaxies, but the estimator shares a definitional dependence on HI mass with the ratio.
