Baryonic solutions and challenges for cosmological models of dwarf galaxies

Nature Astronomy, 2022
Galaxies and their dark-matter haloes have posed several challenges to the dark energy plus cold dark matter (ΛCDM) cosmological model. These discrepancies between observations and theory intensify for the lowest-mass (‘dwarf’) galaxies. ΛCDM predictions

Structure of the galaxy

Reports on Progress in Physics, 1973
The authors have summarized the present knowledge of the stellar content of our galaxy and discussed at some length the use of this knowledge in creating a dynamical framework that can be used in the attempt to understand galaxies in general.

The distribution of dark matter in galaxies

The Astronomy and Astrophysics Review, 2018
The distribution of the non-luminous matter in galaxies of different luminosity and Hubble type is much more than a proof of the existence of dark particles governing the structures of the Universe.

Structure of interacting elliptical radio galaxies

Astrophysics and Space Science, 1993
We have used a numerical method based on elliptical fitting of isophotes to analyse the structural parameters of three pairs of elliptical galaxies containing radio jets. The relationship between tidal interactions and radio activity is also investigated.

STRUCTURE OF GALAXIES

1994
In this contribution I will review the state of the field of structure of galaxies in general terms. I will concentrate on open questions rather than recent achievements. The discussion will not be aimed at experts in the field, but at a rather broader audience.
