DWARF GALAXIES OF THE LOCAL GROUP [PDF]
Annual Review of Astronomy and Astrophysics, 1998 ▪ Abstract The Local Group dwarf galaxies offer a unique window to the detailed properties of the most common type of galaxy in the Universe. In this review, I update the census of Local Group dwarfs based on the most recent distance and radial velocity ...

A profile in FIRE: resolving the radial distributions of satellite galaxies in the Local Group with simulations [PDF]
Monthly notices of the Royal Astronomical Society, 2019 While many tensions between Local Group (LG) satellite galaxies and Λ cold dark matter cosmology have been alleviated through recent cosmological simulations, the spatial distribution of satellites remains an important test of physical models and ...

The Local Group on FIRE: dwarf galaxy populations across a suite of hydrodynamic simulations [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We present a new set of high-resolution hydrodynamic cosmological zoom-in simulations that apply the Feedback In Realistic Environments physics to both Local Group (LG)-like and isolated Milky Way (MW)-like volumes (10 host systems in total with a ...

A Study of the Properties and Dynamics of the Disk of Satellites in a Milky-Way-like Galaxy System
Galaxies, 2023 The dynamics of the satellite systems of Milky-Way-like galaxies offer a useful means by which to study the galaxy formation process in the cosmological context. It has been suggested that the currently observed anisotropic distribution of the satellites

Detectability of Double White Dwarfs in the Local Group with LISA [PDF]
Astrophysical Journal, 2018 Detached double white dwarf (DWD) binaries are one of the main science cases for the Laser Interferometer Space Antenna (LISA). As the most numerous LISA sources, they will provide important contributions toward understanding binary evolution, supernovae

The C/M Ratio of AGB Stars in the Local Group Galaxies
Universe, 2022 The number ratio of carbon-rich to oxygen-rich asymptotic giant branch (AGB) stars (the so-called C/M ratio) is closely related to the evolution environment of the host galaxy.

MOND simulation suggests an origin for some peculiarities in the Local Group [PDF]
Astronomy & Astrophysics, 2017 Context. The Milky Way (MW) and Andromeda (M 31) galaxies possess rotating planes of satellites. The formation of these planes has not been explained satisfactorily so far.

Connecting the First Galaxies with Ultrafaint Dwarfs in the Local Group: Chemical Signatures of Population III Stars [PDF]
, 2017 We investigate the star formation history (SFH) and chemical evolution of isolated analogs of Local Group (LG) ultrafaint dwarf galaxies (UFDs; stellar mass range of ) and gas-rich, low-mass dwarfs (Leo P analogs; stellar mass range of ).

The 2018 Census of Luminous Blue Variables in the Local Group [PDF]
Research Notes of the AAS, 2018 Luminous Blue Variables (LBVs, S Doradus variables, Hubble-Sandage variables) are evolved massive stars undergoing dramatic photometric and spectroscopic variations (Humphreys & Davidson 1994).

Modelling chemical abundance distributions for dwarf galaxies in the Local Group: The impact of turbulent metal diffusion [PDF]
, 2017 We investigate stellar metallicity distribution functions (MDFs), including Fe and α-element abundances, in dwarf galaxies from the Feedback in Realistic Environment (FIRE) project. We examine both isolated dwarf galaxies and those that are satellites of
