of the Large Magellanic Cloud (LMC) with the Milky Way and its neighbourhood. An …

The dark matter profile of the Milky Way inferred from its circular velocity curve

X Ou, AC Eilers, L Necib, A Frebel - Monthly Notices of the Royal …, 2024 - academic.oup.com
In this paper, we construct the circular velocity curve of the Milky Way out to∼ 30 kpc,
providing an updated model of the dark matter density profile. We derive precise parallaxes …

Constraining Dark Energy from the Local Group Dynamics

D Benisty, AC Davis, NW Evans - The Astrophysical Journal …, 2023 - iopscience.iop.org

Structure, Kinematics, and Observability of the Large Magellanic Cloud's Dynamical Friction Wake in Cold versus Fuzzy Dark Matter

HR Foote, G Besla, P Mocz… - The Astrophysical …, 2023 - iopscience.iop.org
Abstract The Large Magellanic Cloud (LMC) will induce a dynamical friction (DF) wake on
infall to the Milky Way (MW). The MW's stellar halo will respond to the gravity of the LMC and …

Weighing Milky Way and Andromeda in an expanding ΛCDM Universe-Decreasing the Local Group mass

D Benisty - Astronomy & Astrophysics, 2024 - aanda.org
The dynamics of the Local Group (LG), especially the contribution of the Milky Way (MW)
and Andromeda (M 31) galaxies, is sensitive to the presence of dark energy. This work …

Evidence for a Massive Andromeda Galaxy Using Satellite Galaxy Proper Motions

E Patel, KS Mandel - The Astrophysical Journal, 2023 - iopscience.iop.org
We present new mass estimates for Andromeda (M31) using the orbital angular momenta of
four satellite galaxies (M33, NGC 185, NGC 147, and IC 10) derived from existing proper …

From high resolution cosmological simulations of the Local Group in a realistic environment,
namely HESTIA simulations, we study the position and kinematic deviations that may arise …

On the Corotation of Milky Way Satellites: LMC-mass Satellites Induce Apparent Motions in Outer Halo Tracers

N Garavito-Camargo, AM Price-Whelan… - The Astrophysical …, 2024 - iopscience.iop.org
Understanding the physical mechanism behind the formation of a corotating thin plane of
satellite galaxies, like the one observed around the Milky Way (MW), has been challenging …

The Local Group's mass: probably no more than the sum of its parts

T Sawala, M Teeriaho… - Monthly Notices of the …, 2023 - academic.oup.com
The total mass of the Local Group and the masses of its primary constituents, the Milky Way
(MW) and M31, are important anchors for several cosmological questions. Recent …
