On the dynamics of the Sagittarius dwarf galaxy [PDF]
Monthly Notices of the Royal Astronomical Society, 1995 We use numerical simulations to test the feasibility of the suggestion by Ibata et al. (1994) that the excess population of stars which they discovered in the Sagittarius region may be the disrupted remains of a dwarf spheroidal galaxy. We find that a Fornax-like model for the pre-disruption system can indeed reproduce the data.

Near IR imaging of Centaurus group dwarf elliptical galaxies
, 2016 Detailed studies of dwarf galaxies in the Local Group have revealed an amazing diversity in their star formation histories. Young and intermediate-age stellar populations are observed in some gas-poor dwarf ellipticals, like Fornax and Carina, where ...

The Astrophysical Journal, 2023 Dwarf galaxies located in extremely underdense cosmic voids are excellent test beds for disentangling the effects of large-scale environments on galaxy formation and evolution. We present the first results of the Dwarfs in Void Environments Survey, which

The Astrophysical JournalWe are entering an era in which we will be able to detect and characterize hundreds of dwarf galaxies within the Local Volume. It is already known that a strong dichotomy exists in the gas content and star formation properties of field dwarf galaxies ...

Target Selection and Sample Characterization for the DESI LOW-Z Secondary Target Program
The Astrophysical Journal, 2023 We introduce the DESI LOW- Z Secondary Target Survey, which combines the wide-area capabilities of the Dark Energy Spectroscopic Instrument (DESI) with an efficient, low-redshift target selection method.

Dwarf spheroidal galaxies: Keystones of galaxy evolution [PDF]
Publications of the Astronomical Society of the Pacific, 1994 Dwarf spheroidal galaxies are the most insignificant extragalactic stellar systems in terms of their visibility, but potentially very significant in terms of their role in the formation and evolution of much more luminous galaxies. We discuss the present observational data and their implications for theories of the formation and evolution of both dwarf

Story2Board: A Training‐Free Approach for Expressive Visual Storytelling
Computer Graphics Forum, EarlyView.Abstract We present Story2Board, a training‐free framework for expressive storyboard generation from natural language. Existing methods narrowly focus on subject identity, overlooking key aspects of visual storytelling such as spatial composition, background evolution, and narrative pacing.

Dwarf elliptical galaxies: United and divided
, 2015 Although of humble appearance and often overlooked because of their modest physical sizes and low star densities, dwarf elliptical (dE) galaxies revealed themselves as the most common type of galaxies to exist in the Universe today.
