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

open access: yesThe 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.

Mass growth of massive quiescent galaxies in the Illustris TNG simulation

open access: yesActa 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.

Star clusters in unperturbed spiral galaxies

open access: yes, 2008
Stars do not form in isolation, they form in groups known as star clusters. Star clusters are seen in a wide range of galaxies and environments. Their presence reveals the history of the host galaxy and the processes of its star formation.

CROCODILE-DWARF: Assembly and Kinematics of Field Dwarf Galaxies with GADGET4-OSAKA

open access: yesThe Astrophysical Journal
We present results from CROCODILE-DWARF, a new suite of cosmological zoom-in hydrodynamic simulations of isolated field dwarf galaxies with halo masses of ∼10 ^10 M _⊙ at z = 0, performed with the gadget 4 -osaka code.

Dwarf spheroidal galaxies in the M81 group of galaxies

open access: yes, 2009
We study the properties of the dwarf galaxy population in the nearby interacting M81 group of galaxies. In particular, we are deriving the metallicity distribution functions, the ages and the star formation histories of these dwarf galaxies based on data

The Star Formation History in Local Group Galaxies. I. Ten Dwarf Galaxies

open access: yesThe Astrophysical Journal
The star formation histories (SFHs) of galaxies provide valuable insights into galaxy evolution and stellar physics. Understanding the SFHs enables the study of chemical enrichment of galaxies, star formation triggered by interactions, and the behavior ...

A Search for Faint Resolved Galaxies Beyond the Milky Way in DES Year 6: A New Faint, Diffuse Dwarf Satellite of NGC 55

open access: yesThe Astrophysical Journal
We report results from a systematic wide-area search for faint dwarf galaxies at heliocentric distances from 0.3 to 2 Mpc using the full 6 yr of data from the Dark Energy Survey (DES).

: Early Release Observations – Interplay between dwarf galaxies and their globular clusters in the Perseus galaxy cluster

open access: yes
We present an analysis of globular clusters (GCs) of dwarf galaxies in the Perseus galaxy cluster that explores the relationship between dwarf galaxy properties and their GCs.

Extended Stellar Populations in Ultrafaint Dwarf Galaxies

open access: yesThe Astronomical Journal
The possible existence of stellar halos in low-mass galaxies is being intensely discussed nowadays after some recent discoveries of stars located in the outskirts of dwarf galaxies of the Local Group.
