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

The Astrophysical Journal, 2022
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).

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.

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.

The volumetric star formation law in the Milky Way [PDF]

Astronomy & Astrophysics, 2019
Several open questions on galaxy formation and evolution have their roots in the lack of a universal star formation law that could univocally link the gas properties, such as its density, to the star formation rate (SFR) density.

STAR FORMATION RELATIONS IN THE MILKY WAY [PDF]

The Astrophysical Journal, 2016
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.

Molecular gas and star formation in the Milky Way [PDF]

EPJ Web of Conferences, 2012
The dense molecular gas is the ideal tracer of the spiral structure in the Milky Way, and should be used intensively to solve the puzzle of its structure. In spite of our position inside the plane, we can hope to disentangle the structures, with position-

When the Milky Way turned off the lights: APOGEE provides evidence of star formation quenching in our Galaxy [PDF]

, 2016
Quenching, the cessation of star formation, is one of the most significant events in the life cycle of galaxies. We show here the first evidence that the Milky Way experienced a generalised quenching of its star formation at the end of its thick disk ...

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.
