The star-formation history of the Milky Way Galaxy [PDF]

Proceedings of the International Astronomical Union, 2008
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 ...

Star Formation in the Milky Way: The Infrared View [PDF]

, 2013
I present a brief review of some of the most recent and active topics of star formation process in the Milky Way using mid and far infrared observations, and motivated by the research being carried out by our science group using data gathered by the ...

The Rapid Formation of the Metal Poor Milky Way [PDF]

The Astrophysical Journal
Abstract Our understanding of the assembly timeline of the Milky Way has been transforming along with the dramatic increase in astrometric and spectroscopic data available over the past several years. Many substructures in chemo-dynamical space have been discovered and identified as the remnants of various galactic mergers.

Formation and Evolution of the Milky Way [PDF]

Symposium - International Astronomical Union, 1998
To paint with broad brush strokes, the spectrum of Galactic formation models has as extrema what may be termed the “fast and smooth” and the “slow and lumpy” scenarios. Appropriate or not, to ascribe as champions of these views the works of, respectively, Eggen et al.

Abundance Gradients and the Formation of the Milky Way [PDF]

The Astrophysical Journal, 2001
In this paper we adopt a chemical evolution model, which is an improved version of the Chiappini, Matteucci and Gratton (1997) model, assuming two main accretion episodes for the formation of the Galaxy.

Insight Into the Formation of the Milky Way Through Cold Halo Substructure. I. The ECHOS of Milky Way Formation [PDF]

The Astrophysical Journal, 2009
We identify ten -- seven for the first time -- elements of cold halo substructure (ECHOS) in the volume within 17.5 kpc of the Sun in the inner halo of the Milky Way.

The Formation of the Milky Way in the Cosmological Context [PDF]

, 2001
The formation of the Milky Way is discussed within the context of the cold dark matter scenario. Several problems arise which can be solved if the Galaxy experienced an early phase of gas heating and decoupling from the dark matter substructure.

Constraining the formation of the Milky Way: Ages [PDF]

EPJ Web of Conferences, 2013
We present a new approach for studying the chemodynamical evolution of the Milky Way, which combines a thin disk chemical evolution model with the dynamics from N-body simulation of a galaxy with properties similar to those of our Galaxy. A cosmological re-simulation is used as a surrogate in order to extract ∼ 11 Gyrs of self-consistent dynamical ...

Dust formation in Milky Way-like galaxies [PDF]

Monthly Notices of the Royal Astronomical Society, 2016
We introduce a dust model for cosmological simulations implemented in the moving-mesh code arepo and present a suite of cosmological hydrodynamical zoom-in simulations to study dust formation within galactic haloes.

The simulation of molecular clouds formation in the Milky Way [PDF]

Monthly Notices of the Royal Astronomical Society, 2012
Using 3D hydrodynamic calculations we simulate formation of molecular clouds in the Galaxy. The simulations take into account molecular hydrogen chemical kinetics, cooling and heating processes.
