From dawn till disk: Milky Way’s turbulent youth revealed by the APOGEE+Gaia data [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2022
We use accurate estimates of aluminium abundance from the APOGEE Data Release 17 and Gaia Early Data Release 3 astrometry to select a highly pure sample of stars with metallicity −1.5 ≲ [Fe/H] ≲ 0.5 born in-situ in the Milky Way proper.

The Poor Old Heart of the Milky Way [PDF]

open access: yesAstrophysical Journal, 2022
Our Milky Way should host an ancient, metal-poor, and centrally concentrated stellar population, which reflects the star formation and enrichment in the few most massive progenitors that coalesced at high redshift to form the proto-Galaxy.

Gaia Data Release 3. Mapping the asymmetric disc of the Milky Way [PDF]

open access: yesAstronomy & Astrophysics, 2022
With the most recent Gaia data release the number of sources with complete 6D phase space information (position and velocity) has increased to well over 33 million stars, while stellar astrophysical parameters are provided for more than 470 million ...

Formation of the Milky Way

open access: yes, 1997
We review observational evidence bearing on the formation of a prototypical large spiral galaxy, the Milky Way. New ground- and space-based studies of globular star clusters and dwarf spheroidal galaxies provide a wealth of information to constrain theories of galaxy formation.

Star Formation in the Local Milky Way [PDF]

open access: yesProceedings of the International Astronomical Union, 2015
AbstractStudies of molecular clouds and young stars near the sun have provided invaluable insights into the process of star formation. Indeed, much of our physical understanding of this topic has been derived from such studies. Perhaps the two most fundamental problems confronting star formation research today are: 1) determining the origin of stellar ...

The origin of physical variations in the star formation law [PDF]

open access: yes, 2013
Observations of external galaxies and of local star-forming clouds in the Milky Way have suggested a variety of star formation laws, i.e., simple direct relations between the column density of star formation (Sigma_SFR: the amount of gas forming stars ...

Early formation and recent starburst activity in the nuclear disk of the Milky Way [PDF]

open access: yes, 2019
The nuclear disk is a dense stellar structure at the centre of the Milky Way, with a radius of ~150 pc (ref. 1 ). It has been a place of intense star formation in the past several tens of millions of years 1 – 3 , but its overall formation history has ...

Phylogeny of the Milky Way’s inner disk and bulge populations: Implications for gas accretion, (the lack of) inside-out thick disk formation, and quenching [PDF]

open access: yesAstronomy & Astrophysics, 2018
We show that the bulge and the disk of the Milky Way (MW) at R ≲ 7 kpc are well described by a unique chemical evolution and a two-phase star formation history (SFH). We argue that the populations within this inner disk, not the entire disk, are the same,
