Giant Halos in Dwarf Irregular Galaxies vs. Dwarf Elliptical Galaxies [PDF]
Proceedings of the International Astronomical Union, 2005 We present a discovery of a giant stellar halo in NGC 6822, a dwarf irregular galaxy in the Local Group. This halo is mostly made of old red giants, showing striking features: 1) it is several times larger than the main body of the galaxy seen in the ...

Sagittarius: The Nearest Dwarf Galaxy [PDF]
Monthly Notices of the Royal Astronomical Society, 1995 We have discovered a new Galactic satellite galaxy in the constellation of Sagittarius. The Sagittarius dwarf galaxy is the nearest galaxy known, subtends an angle of $> 10$ degrees on the sky, lies at a distance of $24 \kpc$ from the Sun, $\sim 16 \kpc$

Star forming dwarf galaxies [PDF]
, 2011 Star forming dwarf galaxies (SFDGs) have a high gas content and low metallicities, reminiscent of the basic entities in hierarchical galaxy formation scenarios.

The Canis Major Dwarf Galaxy [PDF]
Publications of the Astronomical Society of Australia, 2004 Recent observational evidence suggests that the Sagittarius dwarf galaxy represents the only major ongoing accretion event in the Galactic halo, accounting for the majority of stellar debris identified there. This paper summarizes the recent discovery of

Symposium - International Astronomical Union, 1998 We review the observational evidences for tidal dwarf galaxies, a class of small galaxies formed out of the tidal debris of collisions between massive galaxies. Tidal dwarfs are found far from the interacting parent galaxies, associated with massive clouds of atomic hydrogen located at the tip of long tidal tails.

Dwarf elliptical galaxies as ancient tidal dwarf galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2013 The formation of tidal dwarf galaxies (TDGs) is triggered by the encounters of already existing galaxies. Their existence is predicted from numerical calculations of encountering galaxies and is also well documented with observations. The numerical calculations on the formation of TDGs furthermore predict that TDGs cannot contain significant amounts of

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.
