Hunting for low-surface brightness features in nearby galaxy groups [PDF]
arXiv, 2019 On the scale of dwarf galaxies, several tensions between observations and the theory of structure formation have been identified in the Local Group of galaxies. One of them, the plane-of-satellite problem describes the distribution and motion of dwarf galaxies around their hosts being planar and co-moving.

American Journal of Political Science, Volume 68, Issue 2, Page 767-782, April 2024.Abstract This article works to show that machine translation and interpretation technologies can play significant roles in addressing language barriers in democratic polities, including beyond the state. Numerous shared‐language or interpretation models have been proposed to address such barriers, while possible machine models have largely been ...

Star Formation Histories of Local Group Dwarf Galaxies [PDF]

Meetings, eds. T. X. Thuan, C. Balkowski, V. Cayatte, & J. Tran Thanh (Paris:
Editions Frontieres), 193-202, 1998 40 galaxies are currently known as, or suspected to be Local Group members within a radius of 1.8 Mpc. 37 of these galaxies are dwarf galaxies with M_B > -18.5 mag. I present a compilation of the star formation histories of dwarf irregulars, dwarf ellipticals, and dwarf spheroidals in the Local Group, and visualize their evolutionary histories through ...

Dark matter in dwarf galaxies [PDF]
arXiv, 2017 Although the cusp-core controversy for dwarf galaxies is seen as a problem, I argue that the cored central profiles can be explained by flattened cusps because they suffer from conflicting measurements and poor statistics and because there is a large number of conventional processes that could have flattened them since their creation, none of which ...

Evolutionary Histories of Dwarf Galaxies in the Local Group [PDF]
1999, "The Stellar Content of the Local Group", IAU Symp. 192,
eds. P. Whitelock & R. Cannon (Provo: ASP), 17-38, 1998 The star formation histories of Local Group (LG) dwarf galaxies and more distant potential LG members are reviewed. Problems in defining the spatial extent of the LG and membership are briefly discussed. The morphological types found in the LG are presented, and it is suggested that we see continuous evolution from low-mass dwarf irregulars (dIrrs) to ...
