Dwarf Galaxies with the Highest Concentration Are Not Thicker than Ordinary Dwarf Galaxies
The Astrophysical Journal, 2023 The formation mechanism of high-concentration dwarf galaxies is still a mystery. We perform a comparative study of the intrinsic shape of nearby low-mass galaxies with different stellar concentration.

Giant Halos in Dwarf Irregular Galaxies vs. Dwarf Elliptical Galaxies [PDF]
Proceedings of the International Astronomical Union, 2005 We present a discovery of a giant stellar halo in NGC 6822, a dwarf irregular galaxy in the Local Group. This halo is mostly made of old red giants, showing striking features: 1) it is several times larger than the main body of the galaxy seen in the ...

Globular Clusters in Dwarf Galaxies [PDF]
The Astronomical Journal, 2005 Data are presently available on the luminosities and half-light radii of 101 globular clusters associated with low-luminosity parent galaxies. The luminosity distribution of globulars embedded in dwarf galaxies having $M_{v} > -16$ is found to differ ...

Symposium - International Astronomical Union, 1998 We review the observational evidences for tidal dwarf galaxies, a class of small galaxies formed out of the tidal debris of collisions between massive galaxies. Tidal dwarfs are found far from the interacting parent galaxies, associated with massive clouds of atomic hydrogen located at the tip of long tidal tails.

Proton Acceleration with Relativistic Electromagnetic Shock. [PDF]
Adv Sci (Weinh)New Ion Acceleration Mechanism! A novel cosmic‐ray proton acceleration mechanism is proposed, where relativistic electromagnetic shocks accelerate protons transversely. Hamiltonian analysis yields a scaling law linking the proton energy to the minimum longitudinal thickness of the shock.

Dwarf elliptical galaxies as ancient tidal dwarf galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2013 The formation of tidal dwarf galaxies (TDGs) is triggered by the encounters of already existing galaxies. Their existence is predicted from numerical calculations of encountering galaxies and is also well documented with observations. The numerical calculations on the formation of TDGs furthermore predict that TDGs cannot contain significant amounts of

An Overview of the Dwarf Galaxy Survey [PDF]
Publications of the Astronomical Society of the Pacific, 2013 The Dwarf Galaxy Survey (DGS) program is studying low-metallicity galaxies using 230h of far-infrared (FIR) and submillimetre (submm) photometric and spectroscopic observations of the Herschel Space Observatory and draws to this a rich database of a wide range of wavelengths tracing the dust, gas and stars.
