Its bulge and nucleus are the subject of numerous studies (e.g. The NFW profile, derived from those simulations, predicts a cuspy distribution in the central parts of the DM haloes (e.g. 2013), while observations especially of dwarf systems show more a core distribution (Oh et al. Those results can be explained by the gravitational potential related to the gas in those simulations, since the gas, which is important in the inner parts, is not accurately introduced in those simulations.Fukushige & Makino 1997; Navarro, Frenk & White 1997; Moore et al.

As part of a long-term project to revisit the kinematics and dynamics of the large disc galaxies of the Local Group, we present the first deep, wide-field (∼42 arcmin × 56 arcmin) 3D-spectroscopic survey of the ionized gas disc of Messier 33.

Fabry–Perot interferometry has been used to map its Hα distribution and kinematics at unprecedented angular resolution (≲3 arcsec) and resolving power (∼12 600), with the 1.6 m telescope at the Observatoire du Mont Mégantic.

In the optical bands, it could be considered as a flocculent spiral galaxy, but UV and IR observations show more prominent arms. The optical parameters of M33 are given in Table 1. It is the mean distance estimated by using resolved sources techniques such as Cepheids, Planetary Nebulae Luminosity Function (PNLF) and Tip of the Red Giant Branch (TRGB). Still today, the cusp–core problem remains as one compares observations to predictions, especially for dwarf systems and this, despite the numerous studies on the DM distribution in galaxies in the last 30 years.

The M33 profile presents a small bulge-like component in the IR bands. The optical disc of M33 has a scalelength of ∼9.2 arcmin (2.25 kpc) in the References: (1) Mc Connachie et al. (2008), (3) Galleti, Bellazzini & Ferraro (2004), (4) Magrini et al. While, on large scales, -body cosmological simulations reproduce well the observations, it is more problematic at galaxy scales.
