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 ...

The Herschel Dwarf Galaxy Survey [PDF]
Astronomy & Astrophysics, 2019 The sensitive infrared telescopes, Spitzer and Herschel, have been used to target low-metallicity star-forming galaxies, allowing us to investigate the properties of their interstellar medium (ISM) in unprecedented detail.

The dwarf galaxy satellite system of Centaurus A [PDF]
Astronomy & Astrophysics, 2019 Dwarf galaxy satellite systems are essential probes to test models of structure formation, making it necessary to establish a census of dwarf galaxies outside of our own Local Group. We present deep FORS2 VI band images from the ESO Very Large Telescope (

An Overview of the Dwarf Galaxy Survey [PDF]
Publications of the Astronomical Society of the Pacific, 2013 The Dwarf Galaxy Survey (DGS) program is studying low-metallicity galaxies using 230h of far-infrared (FIR) and submillimetre (submm) photometric and spectroscopic observations of the Herschel Space Observatory and draws to this a rich database of a wide range of wavelengths tracing the dust, gas and stars.

The Pristine dwarf galaxy survey–V. The edges of the dwarf galaxy Hercules
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT We present a new spectroscopic study of 175 stars in the vicinity of the dwarf galaxy Hercules (d ∼ 132 kpc) with data from the Anglo-Australian Telescope and its AAOmega spectrograph together with the Two Degree Field multi-object system to solve the conundrum that whether Hercules is tidally disrupting.

Formation of a Massive Lenticular Galaxy Under the Tidal Interaction with a Group of Dwarf Galaxies
The Astrophysical Journal Letters, 2023 Based on the atomic-hydrogen (H i ) observations using the Five-hundred-meter Aperture Spherical radio Telescope, we present a detailed study of the gas-rich massive S0 galaxy NGC 1023 in a nearby galaxy group.

Snake in the Clouds: a new nearby dwarf galaxy in the Magellanic bridge* [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We report the discovery of a nearby dwarf galaxy in the constellation of Hydrus, between the Large and the Small Magellanic Clouds. Hydrus 1 is a mildy elliptical ultra-faint system with luminosity MV ∼ −4.7 and size 53 ± 3 pc, located 28 kpc from the
