## TL;DR

This paper argues that the observed cored profiles in dwarf galaxies can be explained by flattened cusps due to measurement issues and conventional processes, without invoking new physics, thus addressing the cusp-core controversy.

## Contribution

It offers a reinterpretation of dwarf galaxy profiles, suggesting that cored profiles are consistent with flattened cusps caused by known processes, challenging the need for new physics.

## Key findings

- Cored profiles can be explained by flattened cusps.
- Measurement conflicts and poor statistics affect profile interpretation.
- Conventional processes may have flattened cusps since galaxy formation.

## Abstract

Although the cusp-core controversy for dwarf galaxies is seen as a problem, I argue that the cored central profiles can be explained by flattened cusps because they suffer from conflicting measurements and poor statistics and because there is a large number of conventional processes that could have flattened them since their creation, none of which requires new physics. Other problems, such as "too big to fail", are not discussed.
