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.

The Rapid Formation of the Metal-poor Milky Way
The Astrophysical JournalOur 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.

The formation of the Galactic bulge of the Milky Way [PDF]
EPJ Web of Conferences, 2012 We aim to determine if the bulge formed via mergers as predicted by Cold Dark Matter (CDM) theory, or from disk instabilities, as suggested by its boxy shape, or both processes. We are observing about 28,000 bulge stars in fields that span longitudes of −

Gas and Star Formation in Satellites of Milky Way Analogs
The Astrophysical JournalWe have imaged the entirety of eight (plus one partial) Milky Way (MW)–like satellite systems, a total of 42 (45) satellites, from the Satellites Around Galactic Analogs II catalog in both H α and H i with the Canada–France–Hawaii Telescope and the ...

Star formation law in the Milky Way [PDF]
Publications of the Astronomical Society of Japan, 2017 Abstract The Schmidt law (SF law) in the Milky Way was investigated using 3D distribution maps of H ii regions and H i and molecular (H2) gases with spatial resolutions of ∼1 kpc in the Galactic plane and a few tens of pc in the vertical direction. H ii regions were shown to be distributed in a star-forming (SF) disk with nearly constant

STAR FORMATION RELATIONS IN THE MILKY WAY [PDF]
The Astrophysical Journal, 2016 ABSTRACT The relations between star formation and properties of molecular clouds (MCs) are studied based on a sample of star-forming regions in the Galactic Plane. Sources were selected by having radio recombination lines to provide identification of associated MCs and dense clumps. Radio continuum emission and mid-infrared emission were

Clues to the formation of the Milky Way’s thick disk [PDF]
Astronomy & Astrophysics, 2015 We analyse the chemical properties of a set of solar vicinity stars, and show that the small dispersion in abundances of α-elements at all ages provides evidence that the SFH has been uniform throughout the thick disk. In the context of long time scale infall models, we suggest that this result points either to a limited dependence of the gas accretion

The formation and early evolution of the Milky Way [PDF]
Symposium - International Astronomical Union, 1985 In broad outline, the traditional picture for the formation of the Milky Way can be summarized as follows. The proto-galaxy consisted of a slowly rotating cloud of metal-free gas that cooled by bremsstrahlung and recombination radiation. As the internal pressure of the gas decreased, it collapsed in stages with smaller dimensions, faster rotation ...
