Dwarf galaxy formation induced by galaxy interactions [PDF]
, 2000 Growing evidence has been accumulated for that some gas-rich dwarf galaxies are formed from material liberated by galaxy collisions and/or mergers. Also, gas-poor dwarf elliptical galaxies are often found in the central regions of clusters of galaxies.

APOGEE Chemical Abundances of the Sagittarius Dwarf Galaxy [PDF]
, 2017 The Apache Point Observatory Galactic Evolution Experiment provides the opportunity of measuring elemental abundances for C, N, O, Na, Mg, Al, Si, P, K, Ca, V, Cr, Mn, Fe, Co, and Ni in vast numbers of stars.

NIHAO XV: the environmental impact of the host galaxy on galactic satellite and field dwarf galaxies [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We study the impact of the host on dwarf galaxy properties using four new Milky Way-like, ultra high-resolution simulations, ($N_{\rm part} >10^7$) from the NIHAO project. We split our sample in satellite ($R 2.5 R_{\rm 200}$) galaxies.

Constraining Star-Formation Driven Outflows in Local Dwarf Galaxies with Herschel
Physical Sciences Forum, 2023 Galactic feedback (i.e., outflows) plays a fundamental role in regulating galaxy formation and evolution. We investigate the physical properties of galactic outflows in a sample of 29 local low-metallicity dwarf galaxies drawn from the Dwarf Galaxy ...

The Canis Major Dwarf Galaxy [PDF]
, 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

Discovery of Diffuse Dwarf Galaxy Candidates around M101 [PDF]
, 2017 We have conducted a search of a 9 deg2 region of the Canada–France–Hawaii-Telescope Legacy Survey around the Milky Way analog M101 (D ∼ 7 Mpc), in order to look for previously unknown low-surface-brightness galaxies.

The Astrophysical Journal Letters, 2023 Local low-metallicity dwarf galaxies are relics of the early universe and are thought to hold clues into the origins of supermassive black holes. While recent studies are uncovering a growing population of active galactic nuclei (AGNs) in dwarf galaxies,

Warp or lag? The ionized and neutral hydrogen gas in the edge-on dwarf galaxy UGC 1281 [PDF]
, 2011 The properties of gas in the halos of galaxies constrain global models of the interstellar medium. Kinematical information is of particular interest since it is a clue to the origin of the gas. Until now mostly massive galaxies have been investigated for

R-process enrichment from a single event in an ancient dwarf galaxy [PDF]
Nature, 2015 Elements heavier than zinc are synthesized through the rapid (r) and slow (s) neutron-capture processes. The main site of production of the r-process elements (such as europium) has been debated for nearly 60 years.
