Dust in Nearby DWARF Galaxies [PDF]

open access: yesSymposium - International Astronomical Union, 1994
The aim of the present paper is to look for the gas-to-dust ratio in different types of galaxies and for a correlation between this ratio and the metallicity in dwarf galaxies. The recent compilation of data on nearby galaxies by Schmidt & Boller (1992, hereinafter SB) including HI and dust ...

ANGULAR MOMENTUM OF DWARF GALAXIES [PDF]

open access: yesThe Astrophysical Journal Letters, 2016
ABSTRACT We present measurements of baryonic mass and specific angular momentum (sAM) in 14 rotating dwarf Irregular (dIrr) galaxies from the LITTLE THINGS sample.

The PAndAS View of the Andromeda Satellite System. IV. Global Properties

open access: yesThe Astrophysical Journal, 2023
We build a statistical framework to infer the global properties of the satellite system of the Andromeda galaxy (M31) from the properties of individual dwarf galaxies located in the Pan-Andromeda Archaelogical Survey (PAndAS) and the previously ...

Ultra-Compact Dwarf Galaxies in Galaxy Clusters [PDF]

open access: yesPublications of the Astronomical Society of Australia, 2004
AbstractWe review the evidence that the ultra-compact dwarf (UCD) galaxies we recently discovered in the Fornax Cluster form a new, previously unknown class of galaxies and we discuss possible scenarios for their formation. We then present recent results that UCDs are also present in the Virgo Cluster, and that there is a much larger than expected ...

On the dynamics of the Sagittarius dwarf galaxy [PDF]

open access: yesMonthly 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.

Environment Matters: Predicted Differences in the Stellar Mass–Halo Mass Relation and History of Star Formation for Dwarf Galaxies

open access: yesThe Astrophysical Journal
We 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 ...

Dwarfs in Void Environments (DIVE): The Stellar Kinematics of Void Dwarf Galaxies Using the Keck Cosmic Web Imager

open access: yesThe 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

Form flows function: Learner‐centered game Re‐design in a STEM classroom

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Re‐designing games facilitates interest‐driven learning and immerses learners in systems thinking. However, there are limited studies exploring how the form and function of tabletop games influence learners' design decisions and learning experiences. To address this gap, we conducted a mixed‐methods study in a STEM classroom in western Canada.

Dwarf spheroidal galaxies: Keystones of galaxy evolution [PDF]

open access: yesPublications 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

open access: yes, 2006
In this work the results are presented of an extensive search for Long Period Variables stars (LPVs) in a sample of Local Group irregular dwarf galaxies.
