The Cusp–Core Problem in Gas-Poor Dwarf Spheroidal Galaxies
Galaxies, 2021 This review deals with the inconsistency of inner dark matter density profiles in dwarf galaxies, known as the cusp–core problem. In particular, we aim to focus on gas-poor dwarf galaxies.

Stellar evolution and feedback connections to stellar dynamics [PDF]
Proceedings of the International Astronomical Union, 2006 AbstractUntil a few years ago, the common paradigm for the formation of Globular Clusters (GCs) was that they constitute a ‘simple stellar population’ in which all the stars were formed from a chemically homogeneous cluster medium within a relatively short interval of time, at the beginning of the galactic life.

Stellar dynamics and feedback connections to stellar evolution [PDF]
Proceedings of the International Astronomical Union, 2006 AbstractIn dense stellar systems, dynamical interactions between objects inevitably lead to frequent formation of exotic stellar objects and multiple systems, thereby imposing new questions for the stellar evolution theory. The evolutionary path of such systems could be different from that of the unperturbed objects, therefore, we must re-evaluate ...

Feedback and the formation of dwarf galaxy stellar haloes [PDF]
Monthly Notices of the Royal Astronomical Society, 2009 Stellar population studies show that low mass galaxies in all environments exhibit stellar halos that are older and more spherically distributed than the main body of the galaxy. In some cases, there is a significant intermediate age component that extends beyond the young disk. We examine a suite of Smoothed Particle Hydrodynamic (SPH) simulations and

Modeling for Stellar Feedback in Galaxy Formation Simulations [PDF]
The Astrophysical Journal, 2017 Abstract Various heuristic approaches to model unresolved supernova (SN) feedback in galaxy formation simulations exist to reproduce the formation of spiral galaxies and the overall inefficient conversion of gas into stars. Some models, however, require resolution-dependent scalings.

Stellar Feedback and Resolved Stellar IFU Spectroscopy in the Nearby Spiral Galaxy NGC 300 [PDF]
The Astrophysical Journal, 2020 Abstract We present MUSE integral field unit (IFU) observations of five individual H ii regions in two giant star-forming complexes in the low-metallicity, nearby dwarf spiral galaxy NGC 300. In combination with high spatial resolution Hubble Space Telescope photometry, we demonstrate the extraction of stellar spectra and classification ...

Delayed Massive-star Mechanical Feedback at Low Metallicity
The Astrophysical Journal, 2023 The classical model of massive-star mechanical feedback is based on effects at solar metallicity ( Z _⊙ ), yet feedback parameters are very different at low metallicity.

Stellar feedback and triggered star formation [PDF]
Proceedings of the International Astronomical Union, 2009 AbstractYoung, massive stars influence their ambient medium through winds and radiation. The outcome of this feedback depends on the number of massive stars in a star cluster and on the density of the ambient medium. This contribution is based on a comparison of observations to the results of numerical simulations.
