Dynamically defined bulges reveal that early-type galaxies with compact bulges host more massive black holes
Hanjing Shi, Ling Zhu, Sabine Thater +4
We revisit the relation for early-type galaxies by introducing a uniform bulge defined by dynamical decomposition. From the set of nearby galaxies with accuratel…
Lower central dark matter densities in nearby galaxies than predicted by simulations
Yu Lei, Ling Zhu, Meng Yang +9
Baryonic feedback in hydrodynamical simulations is typically invoked to alleviate the core--cusp problem in dwarf galaxies. Yet baryonic processes also induce adiabatic contraction…
Insights into the Physical Nature of Polar Ring Galaxies from H I Observations
Niankun Yu, Han Zheng, Chao-Wei Tsai +10
Polar ring galaxies (PRGs) host an outer ring of gas and stars oriented nearly perpendicular to the main stellar body. They represent extreme examples of misaligned systems and pro…
Dark matter in ALFALFA galaxies: Investigating galaxy-halo connection
Meng Yang, Ling Zhu, Niankun Yu +4
This paper aims to investigate the galaxy-halo connection using a large sample of individual galaxies with integrated spectra. We determine their dark matter conten…
Emulating extended Lyman-alpha haloes around star-forming galaxies
Pengfei Li, Zheng Zheng
Extended Ly emission is commonly observed around star-forming galaxies, opening a window for probing the neutral hydrogen gas in the circumgalactic medium (CGM). In this paper,…
