Baryonic solutions and challenges for cosmological models of dwarf galaxies

LV Sales, A Wetzel, A Fattahi - Nature Astronomy, 2022 - nature.com
Galaxies and their dark-matter haloes have posed several challenges to the dark energy
plus cold dark matter (Λ CDM) cosmological model. These discrepancies between …

Observational constraints on stellar feedback in dwarf galaxies

MLM Collins, JI Read - Nature astronomy, 2022 - nature.com
Feedback to the interstellar medium from ionizing radiation, stellar winds and supernovae is
central to regulating star formation in galaxies. Owing to their low mass (< 109 solar …

A galaxy lacking dark matter

P Van Dokkum, S Danieli, Y Cohen, A Merritt… - Nature, 2018 - nature.com
Studies of galaxy surveys in the context of the cold dark matter paradigm have shown that
the mass of the dark matter halo and the total stellar mass are coupled through a function …

No need for dark matter: resolved kinematics of the ultra-diffuse galaxy AGC 114905

PE Mancera Piña, F Fraternali… - Monthly Notices of …, 2022 - academic.oup.com
We present new H i interferometric observations of the gas-rich ultra-diffuse galaxy AGC
114905, which previous work, based on low-resolution data, identified as an outlier of the …

Self-interacting dark matter can explain diverse galactic rotation curves

A Kamada, M Kaplinghat, AB Pace, HB Yu - Physical review letters, 2017 - APS
The rotation curves of spiral galaxies exhibit a diversity that has been difficult to understand
in the cold dark matter (CDM) paradigm. We show that the self-interacting dark matter …

Radial acceleration relation in rotationally supported galaxies

SS McGaugh, F Lelli, JM Schombert - Physical Review Letters, 2016 - APS
We report a correlation between the radial acceleration traced by rotation curves and that
predicted by the observed distribution of baryons. The same relation is followed by 2693 …

The Local Group on FIRE: dwarf galaxy populations across a suite of hydrodynamic simulations

S Garrison-Kimmel, PF Hopkins… - Monthly Notices of …, 2019 - academic.oup.com
We present a new set of high-resolution hydrodynamic cosmological zoom-in simulations
that apply the Feedback In Realistic Environments physics to both Local Group (LG)-like and …

DarkSUSY 6: an advanced tool to compute dark matter properties numerically

T Bringmann, T Edsjö, P Gondolo, P Ullio… - Journal of Cosmology …, 2018 - iopscience.iop.org
The nature of dark matter remains one of the key science questions. Weakly Interacting
Massive Particles (WIMPs) are among the best motivated particle physics candidates …

Off the baryonic tully–fisher relation: A population of baryon-dominated ultra-diffuse galaxies

PEM Pina, F Fraternali, EAK Adams… - The Astrophysical …, 2019 - iopscience.iop.org
We study the gas kinematics traced by the 21 cm emission of a sample of six H i-rich low
surface brightness galaxies classified as ultra-diffuse galaxies (UDGs). Using the 3D …
