Our Galaxy, the Milky Way, is a benchmark for understanding disk galaxies. It is the only galaxy whose formation history can be studied using the full distribution of stars from faint dwarfs to supergiants. The oldest components provide us with unique insight into how galaxies form and evolve over billions of years. The Galaxy is a luminous (L⋆) barred spiral with a central box/peanut bulge, a dominant disk, and a diffuse stellar halo. Based on global properties, it falls in the sparsely… 

Signatures of the Galactic bar on stellar kinematics unveiled by APOGEE

Bars are common galactic structures in the local universe that play an important role in the secular evolution of galaxies, including the Milky Way. In particular, the velocity distribution of

Gas Dynamics in the Galaxy: Total Mass Distribution and the Bar Pattern Speed

Gas morphology and kinematics in the Milky Way contain key information for understanding the formation and evolution of our Galaxy. We present hydrodynamical simulations based on realistic barred

Tracing the anemic stellar halo of M 101

Models of galaxy formation in a cosmological context predict that massive disk galaxies should have structured extended stellar halos. Recent studies in integrated light, however, report that a few

Resolved Stellar Populations as Tracers of Outskirts

Galaxy haloes contain fundamental clues about the galaxy formation and evolution process: hierarchical cosmological models predict haloes to be ubiquitous and to be (at least in part) the product of

The stellar halos of Milky Way type galaxies in the EAGLE simulations

The stellar halo component of a galaxy contains a wealth of valuable information on the host galaxy's formation history. As the diffuse outskirts of galaxies which have been built up through

A relation between characteristic stellar age of galaxies and their intrinsic shape

Stellar population and stellar kinematic studies provide unique but complementary insights into how galaxies build-up their stellar mass and angular momentum1–3. A galaxy’s mean stellar age reveals

Progress on the structure and evolution of the Milky Way based on LAMOST survey

The Milky Way is, at least for now, the only galaxy that we can obtain the full 3 dimensional spatial and kinematical information of individual stars. This makes it the most important galaxy sample

Combined dynamical effects of the bar and spiral arms in a Galaxy model. Application to the solar neighbourhood

Context. Observational data indicate that the Milky Way is a barred spiral galaxy. Computation facilities and availability of data from Galactic surveys stimulate the appearance of models of the

Abstract This general overview of our understanding of the Galaxy followed the lines of its main structures (halo, disc, bulge/bar) and emphasized some time-domain astronomy contributions. On the one



Milky Way simulations: The Galaxy, its stellar halo and its satellites – insights from a hybrid cosmological approach

Our home galaxy – the Milky Way – is a fairly large spiral galaxy, prototype of the most common morphological class in the local Universe. Although being only a galaxy, it is the only one that can be

The Galaxy and its stellar halo: insights on their formation from a hybrid cosmological approach

We use a series of high-resolution simulations of a 'Milky Way' halo coupled to semi-analytic methods to study the formation of our own Galaxy and its stellar halo. The physical properties of our

Galaxy Disks

The disks of disk galaxies contain a substantial fraction of their baryonic matter and angular momentum, and much of the evolutionary activity in these galaxies, such as the formation of stars,

The New Galaxy: Signatures of Its Formation

▪ Abstract The formation and evolution of galaxies is one of the great outstanding problems of astrophysics. Within the broad context of hierachical structure formation, we have only a crude picture


Bulges are commonly believed to form in the dynamical violence of galaxy collisions and mergers. Here, we model the stellar kinematics of the Bulge Radial Velocity Assay (BRAVA) and find no sign that


Halo stars orbit within the potential of the Milky Way, and hence their kinematics can be used to understand the underlying mass distribution. However, the inferred mass distribution depends

Stars beyond galaxies: the origin of extended luminous haloes around galaxies

We use numerical simulations to investigate the origin and structure of the luminous haloes that surround isolated galaxies. These stellar structures extend out to several hundred kpc away from a

What Shapes the Luminosity Function of Galaxies?

We investigate the physical mechanisms that shape the luminosity function of galaxies in hierarchical clustering models. Beginning with the mass function of dark matter halos in the ΛCDM (Λ cold dark

The distribution function of the Galaxy's dark halo

Starting from the hypothesis that the Galaxy's dark halo responded adiabatically to the infall of baryons, we have constructed a self-consistent dynamical model of the Galaxy that satisfies a large

Nearby stars of the Galactic disc and halo – IV

The Milky Way Galaxy has an age of about 13 billion years. Solar-type stars evolve all the long way to the realm of degenerate objects on essentially this time-scale. This, as well as the particular
