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.

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.

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 ...

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.

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.

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.

Bar Formation in Milky Way type Galaxies

Open Astronomy, 2016
Many barred galaxies, possibly including the Milky Way, have cusps in their centers. There is a widespread belief, however, that the usual bar instability, which occurs in bulgeless galaxy models, is impossible for cuspy models because of the presence of

Gas and Star Formation in Satellites of Milky Way Analogs

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 ...

Kinematic-chemical Analysis and Time Tagging for the Diagonal Ridge Structure of the Galactic Outer Disk with LAMOST Red-giant Branch Stars

The Astronomical Journal, 2023
We investigate the kinematic-chemical distribution of red-giant branch stars from the LAMOST survey crossed matched with Gaia DR2 proper motions, and present time tagging for the well-known ridge structures (diagonal distributions for V _R in the R , V ...
