Overview and public data release of the augmented Auriga Project: cosmological simulations of dwarf and Milky Way-mass galaxies [PDF]

Monthly notices of the Royal Astronomical Society
We present an extended suite of the Auriga cosmological gravo-magnetohydrodynamical “zoom-in” simulations of 40 Milky Way-mass halos and 26 dwarf galaxy-mass halos run with the moving-mesh code arepo.

A time-resolved picture of our Milky Way’s early formation history [PDF]

Nature, 2022
The formation of our Milky Way can be split up qualitatively into different phases that resulted in its structurally different stellar populations: the halo and the disk components1–3.

Evidence for two early accretion events that built the Milky Way stellar halo [PDF]

Monthly notices of the Royal Astronomical Society, 2019
The Gaia Sausage is the major accretion event that built the stellar halo of the Milky Way galaxy. Here, we provide dynamical and chemical evidence for a second substantial accretion episode, distinct from the Gaia Sausage. The Sequoia Event provided the

Weighing the Milky Way

, 2002
We describe an experiment to measure the mass of the Milky Way galaxy. The experiment is based on calculated light travel times along orthogonal directions in the Schwarzschild metric of the Galactic center. We show that the difference is proportional to

Kraken reveals itself – the merger history of the Milky Way reconstructed with the E-MOSAICS simulations [PDF]

Monthly notices of the Royal Astronomical Society, 2020
Globular clusters (GCs) formed when the Milky Way experienced a phase of rapid assembly. We use the wealth of information contained in the Galactic GC population to quantify the properties of the satellite galaxies from which the Milky Way assembled ...

The observed spiral structure of the Milky Way [PDF]

, 2014
The spiral structure of the Milky Way is not yet well determined. The keys to understanding this structure are to increase the number of reliable spiral tracers and to determine their distances as accurately as possible.

Testing Yukawa cosmology at the Milky Way and M31 galactic scales [PDF]

The European Physical Journal C
We address the galaxy rotation curves through the Yukawa gravitational potential emerging as a correction of the Newtonian potential in extended theories of gravity.

The effect of the deforming dark matter haloes of the Milky Way and the Large Magellanic Cloud on the Orphan-Chenab stream [PDF]

, 2022
It has recently been shown that the Large Magellanic Cloud (LMC) has a substantial effect on the Milky Way’s stellar halo and stellar streams. Here, we explore how deformations of the Milky Way and LMC’s dark matter haloes affect stellar streams, and ...

What Does the Milky Way Look Like?

The Astrophysical Journal, 2023
In spite of much work, the overall spiral structure morphology of the Milky Way remains somewhat uncertain. In the last two decades, accurate distance measurements have provided us with an opportunity to solve this issue.

Cosmological Structures behind the Milky Way

, 2005
This paper provides an update to the review on extragalactic large-scale structures uncovered in the Zone of Avoidance (ZOA) by Kraan-Korteweg & Lahav 2000, in particular in the Great Attractor region. Emphasis is given to the penetration of the ZOA with
