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. In the young universe they probably also played a major role in the cosmic reionization. Their abundant presence in the local volume and their youthful character make them ideal objects for ...

THE LOCAL DWARF GALAXIES:BUILDING BLOCKS OFMASSIVE ONES? I.THE FORNAX DWARF GALAXY

Odessa Astronomical Publications, 2008
A chemical evolution of the Local Group dwarf galaxy Fornax is considered in the framework of the merger scenario. We suppose a galactic stellar halo to be formed as separate fragments which then merge; thus, we can calculate the set of such the ...

Mass growth of massive quiescent galaxies in the Illustris TNG simulation

Acta Polytechnica
Interactions between galaxies could potentially lead to increased rates of star formation within these galaxies, potentially leading to the occurrence of multiple core-collapse supernovae and the ejection of hot gas.

Core-collapse Supernovae from the Palomar Transient Factory: Indications for a Different Population in Dwarf Galaxies [PDF]

, 2010
We use the first compilation of 72 core-collapse supernovae (SNe) from the Palomar Transient Factory (PTF) to study their observed subtype distribution in dwarf galaxies compared to giant galaxies.

Dark-matter-free Dwarf Galaxy Formation at the Tips of the Tentacles of Jellyfish Galaxies

The Astrophysical Journal
When falling into a galaxy cluster, galaxies experience a loss of gas due to ram pressure stripping. In particular, disk galaxies lose gas from their disks, and very large tentacles of gas can be formed.
