The star-formation history of the Milky Way Galaxy [PDF]
Proceedings of IAU Symposium 258, (2009), 'The Ages of Stars', eds
Mamajek, Soderblom & Wyse p. 11-22, 2009 The star-formation histories of the main stellar components of the Milky Way constrain critical aspects of galaxy formation and evolution. I discuss recent determinations of such histories, together with their interpretation in terms of theories of disk ...

A Model of Habitability Within the Milky Way Galaxy [PDF]
Astrobiology, 2011 We present a model of the Galactic Habitable Zone (GHZ), described in terms of the spatial and temporal dimensions of the Galaxy that may favour the development of complex life.

Chemodynamical simulations of the Milky Way galaxy [PDF]
The Astrophysical Journal, 2011 We present chemodynamical simulations of a Milky-Way-type galaxy using a self-consistent hydrodynamical code that includes supernova feedback and chemical enrichment, and predict the spatial distribution of elements from oxygen to zinc.

Searching for Milky Way twins: Radial abundance distribution as a strict criterion [PDF]
A&A 676, A57 (2023), 2023 We search for Milky Way-like galaxies among a sample of approximately 500 galaxies. The characteristics we considered of the candidate galaxies are the following: stellar mass M_star, optical radius R_25, rotation velocity V_rot, central oxygen abundance

On the Spiral Structure of the Milky Way Galaxy [PDF]
Astronomy Reports, 2010 We consider the possible pattern of the overall spiral structure of the Galaxy, using data on the distribution of neutral (atomic), molecular, and ionized hydrogen, on the base of the hypothesis of the spiral structure being symmetric, i.e.

Black holes in the milky way galaxy. [PDF]
Proc Natl Acad Sci U S A, 1999 Extremely strong observational evidence has recently been found for the presence of black holes orbiting a few relatively normal stars in our Milky Way Galaxy and also at the centers of some galaxies. The former generally have masses of 4–16 times the mass of the sun, whereas the latter are “supermassive black holes” with millions to billions of ...

An Eclectic View of our Milky Way Galaxy [PDF]
, 2013 The nature of our Milky Way Galaxy is reexamined from an eclectic point of view. Evidence for a central bar, for example, is not reflected in the distribution of RR Lyrae variables in the central bulge [4,5], and it is not clear if either a 2-armed or 4 ...

Milky Way type galaxies in a LCDM cosmology [PDF]
Monthly Notices of the Royal Astronomical Society, 2009 We analyse a sample of 52,000 Milky Way (MW) type galaxies drawn from the publicly available galaxy catalogue of the Millennium Simulation with the aim of studying statistically the differences and similarities of their properties in comparison to our ...

The Milky Way Galaxy as a Strong Gravitational Lens [PDF]
Monthly Notices of the Royal Astronomical Society, 2006 We study the gravitational lensing effects of spiral galaxies by taking a model of the Milky Way and computing its lensing properties. The model is composed of a spherical Hernquist bulge, a Miyamoto-Nagai disc and an isothermal halo. As a strong lens, a

The Milky Way and the evolution of disk galaxies
, 2002 We present a phenomenological approach to the study of disk galaxy evolution, based on i) a detailed modelling of the Milky Way (used as a prototype disk galaxy) and ii) an extension of the model to other disks through some simple scaling relations, obtained in the framework of Cold Dark matter models.
