Reionization of the Local Group of Galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2010 We present the first detailed structure formation and radiative transfer simulations of the reionization history of our cosmic neighbourhood. To this end, we follow the formation of the Local Group of galaxies and nearby clusters by means of constrained ...

, 2015 How dust absorbs and scatters starlight as a function of wavelength (known as the interstellar extinction curve) is crucial for correcting for the effects of dust extinction in inferring the true luminosity and colors of reddened astrophysical objects ...

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 ...

ON THE MASS OF THE LOCAL GROUP [PDF]
The Astrophysical Journal, 2014 We use recent proper motion measurements of the tangential velocity of M31, along with its radial velocity and distance, to derive the likelihood of the sum of halo masses of the Milky Way and M31. This is done using a sample halo pairs in the Bolshoi cosmological simulation of $ $CDM cosmology selected to match properties and environment of the Local

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 ...

Star formation histories of dwarf galaxies in the FIRE simulations: dependence on mass and Local Group environment [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We study star formation histories (SFHs) of 500 dwarf galaxies (stellar mass $M_\ast =10^5\!-\!10^9\, \rm {M}_\odot$) from FIRE-2 cosmological zoom-in simulations. We compare dwarfs around individual Milky Way (MW)-mass galaxies, dwarfs in Local Group (

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 ...

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 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).
