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.

Gas and Star Formation in Satellites of Milky Way Analogs [PDF]

The Astrophysical Journal
We 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 ...

The Star Formation Rate of the Milky Way as seen by Herschel [PDF]

The Astrophysical Journal, 2022
Abstract We present a new derivation of the Milky Way’s current star formation rate (SFR) based on the data of the Herschel InfraRed Galactic Plane Survey (Hi-GAL). We estimate the distribution of the SFR across the Galactic plane from the star-forming clumps identified in the Hi-GAL survey and calculate the total SFR from the sum of ...

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.

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.

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.

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.
