The spatial distribution of globular clusters in dwarf spheroidal galaxies and the timing problem [PDF]
Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACT The dynamical friction time-scale of massive globular clusters (GCs) in the inner regions of cuspy dark haloes in dwarf spheroidal (dSph) galaxies can be much shorter than the Hubble time. This implies that a small fraction of the GCs is expected to be caught close to the centre of these galaxies.

Embedding globular clusters in dark matter minihaloes solves the cusp–core and timing problems in the Fornax dwarf galaxy [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We use a fully GPU N-body code to demonstrate that dark matter (DM) minihaloes, as a new component of globular clusters (GCs), resolve both the timing and cusp–core problems in Fornax if the (five or six) GCs were recently accreted (≤3 Gyr ago) by Fornax.

A too-many dwarf satellite galaxies problem in the MATLAS low-to-moderate density fields [PDF]
Astronomy & AstrophysicsContext.Dwarf galaxy abundances can serve as discernment tests for models of structure formation. Previous small-scale tensions between observations and dark matter-only cosmological simulations may have been resolved with the inclusion of baryonic processes; however, these successes have been largely concentrated on the Local Group dwarfs the feedback

An assessment of the “too big to fail” problem for field dwarf galaxies in view of baryonic feedback effects [PDF]
Astronomy & Astrophysics, 2016 Recent studies have established that extreme dwarf galaxies --whether satellites or field objects-- suffer from the so called "too big to fail" (TBTF) problem. Put simply, the TBTF problem consists of the fact that it is difficult to explain both the measured kinematics of dwarfs and their observed number density within the LCDM framework.

A too-many-dwarf-galaxy-satellites problem in the M 83 group [PDF]
Astronomy & AstrophysicsDwarf galaxies in groups of galaxies provide excellent test cases for models of structure formation. This led to a so-called small-scale crisis, including the famous missing-satellites and too-big-to-fail problems. It was suggested that these two problems can be resolved by introducing baryonic physics to cosmological simulations.
