Dwarf elliptical galaxies as ancient tidal dwarf galaxies [PDF]
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

Identification and Characterization of a Large Sample of Distant Active Dwarf Galaxies in XMM-SERVS
Active dwarf galaxies are important because they contribute to the evolution of dwarf galaxies and can reveal their hosted massive black holes. However, the sample size of such sources beyond the local universe is still highly limited.

The Mass–Metallicity Relation of Dwarf Galaxies at Cosmic Noon from JWST Observations
We present a study of the mass–metallicity relation (MZR) of 51 dwarf galaxies ( M _⋆ ≈ 10 ^6.5 –10 ^9.5 M _⊙ ) at z = 2–3 from the A2744 and SMACS J0723-3732 galaxy cluster fields.

We study the morphologies and structures of 57 dwarf galaxies that are representative of the general population of dwarf galaxies and compare their demographics to a sample of dwarf galaxies hosting optically selected active galactic nuclei (AGNs).

An Overview of the Dwarf Galaxy Survey [PDF]
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 formation of ultra-compact dwarf galaxies and nucleated dwarf galaxies [PDF]
Ultra compact dwarf galaxies (UCDs) have similar properties as massive globular clusters or the nuclei of nucleated galaxies. Recent observations suggesting a high dark matter content and a steep spatial distribution within groups and clusters provide new clues as to their origins.

The Pristine dwarf galaxy survey–V. The edges of the dwarf galaxy Hercules
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.

DWARF GALAXIES AND THE COSMIC WEB [PDF]
We use a cosmological simulation of the formation of the Local Group of Galaxies to identify a mechanism that enables the removal of baryons from low-mass halos without appealing to feedback or reionization. As the Local Group forms, matter bound to it develops a network of filaments and pancakes.
