A Milky Way-like barred spiral galaxy at a redshift of 3
The majority of massive disk galaxies in the local Universe show a stellar barred structure in
their central regions, including our Milky Way,. Bars are supposed to develop in dynamically …

Detecting a disc bending wave in a barred-spiral galaxy at redshift 4.4
The recent discovery of barred spiral galaxies in the early Universe (z> 2) poses questions
of how these structures form and how they influence galaxy evolution in the early Universe …

The profiles of bars in spiral galaxies
We present an analysis of major-axis surface-brightness profiles of bars in a volume-limited
sample of 182 barred spiral galaxies, using Spitzer 3.6 m images. Unlike most previous …

The JWST view of the barred galaxy population in the SMACS0723 galaxy cluster
Context. The cosmic evolution of the barred galaxy population provides key information
about the secular evolution of galaxies and the settling of rotationally dominated discs. Aims …

Bars and boxy/peanut bulges in thin and thick discs-II. Can bars form in hot thick discs?
The Milky Way and a majority of external galaxies possess a thick disc. However, the
dynamical role of the (geometrically) thick disc in the bar formation and evolution is not fully …

A JWST investigation into the bar fraction at redshifts 1 ≤ z ≤ 3
The presence of a stellar bar in a disc galaxy indicates that the galaxy hosts in its main part a
dynamically settled disc and that bar-driven processes are taking place in sha** its …

Looking for a needle in a haystack: Measuring the length of a stellar bar
One of the challenges related to stellar bars is to accurately determine the length of the bar
in a disc galaxy. In the literature, a wide variety of methods have been employed to measure …

Disc galaxies are still settling-Discovery of the smallest nuclear discs and their young stellar bars
When galactic discs settle and become massive enough, they are able to form stellar bars.
