Ultrafaint Dwarfs in a Milky Way Context: Introducing the Mint Condition DC Justice League Simulations [PDF]
, 2020 We present results from the “Mint” resolution DC Justice League suite of Milky Way–like zoom-in cosmological simulations, which extend our study of nearby galaxies down into the ultrafaint dwarf (UFD) regime for the first time.

A synthetic view on structure and evolution of the Milky Way [PDF]
, 2003 Since the Hipparcos mission and recent large scale surveys in the optical and the near-infrared, new constraints have been obtained on the structure and evolution history of the Milky Way.

Detecting Fast Radio Bursts in the Milky Way [PDF]
, 2021 Fast Radio Bursts (FRBs) are highly energetic transient events with duration of order of microseconds to milliseconds and of unknown origin. They are known to lie at cosmological distances, through localisation to host galaxies. Recently, an FRB-like event was seen from the Milky Way magnetar SGR 1935+2154 by the CHIME and STARE2 telescopes.

Timing the Early Assembly of the Milky Way with the H3 Survey [PDF]
Astrophysical Journal, 2020 The archeological record of stars in the Milky Way opens a uniquely detailed window into the early formation and assembly of galaxies. Here we use 11,000 main-sequence turn-off stars with well-measured ages, , , and orbits from the H3 Survey and Gaia to ...

Distant Echoes of the Milky Way’s Last Major Merger
The Astrophysical Journal, 2023 The majority of the Milky Way’s stellar halo consists of debris from our galaxy’s last major merger, the Gaia-Sausage-Enceladus (GSE). In the past few years, stars from the GSE have been kinematically and chemically studied in the inner 30 kpc of our ...

The Milky Way Nuclear Star Cluster [PDF]
, 2011 In the center of the Milky Way, as well as in many other galaxies, a compact star cluster around a very massive black hole is observed. One of the possible explanations for the formation of such Nuclear Star Clusters is based on the 'merging' of globular

The Milky Way in Molecular Clouds: A New Complete CO Survey [PDF]
, 2000 New large-scale CO surveys of the first and second Galactic quadrants and the nearby molecular cloud complexes in Orion and Taurus, obtained with the CfA 1.2 m telescope, have been combined with 31 other surveys obtained over the past two decades with ...

A catalogue of masses, structural parameters, and velocity dispersion profiles of 112 Milky Way globular clusters [PDF]
, 2018 We have determined masses, stellar mass functions, and structural parameters of 112 Milky Way globular clusters by fitting a large set of N-body simulations to their velocity dispersion and surface density profiles.

The connection between the host halo and the satellite galaxies of the Milky Way [PDF]
, 2016 Many properties of the Milky Way's dark matter halo, including its mass assembly history, concentration, and subhalo population, remain poorly constrained.

The X-shaped Bulge of the Milky Way revealed by WISE [PDF]
, 2016 The Milky Way bulge has a boxy/peanut morphology and an X-shaped structure. This X-shape has been revealed by the `split in the red clump' from star counts along the line of sight toward the bulge, measured from photometric surveys. This boxy, X-shaped bulge morphology is not unique to the Milky Way and such bulges are observed in other barred spiral ...
