The onset of stellar bars at Cosmic Noon. Bar-driven quenching and AGN co-evolution in a mature disc galaxy
Luca Costantin, Lorenzo Morelli, Cristina Cabello +15
The paper analyzes a barred spiral galaxy at redshift 1.17 using JWST NIRSpec data, showing that the bar formed early (z~5) and contributed to long‑term star‑formation quenching wh…
Dark gaps and resonances in barred galaxies
Taehyun Kim, Dimitri A. Gadotti, Myeong-gu Park +4
Dark gaps, low surface brightness regions along the bar minor axis, are expected to form as a consequence of secular evolution in barred galaxies. Although several studies have pro…
Conditions for Bar Formation in Bulgeless Disk Galaxies
Dajeong Jang, Woong-Tae Kim, Yun Hee Lee
While bars are commonly observed in disk galaxies, the precise conditions governing their formation remain incompletely understood. To investigate these conditions, we perform a su…
The Tremaine-Weinberg method at high redshifts
Mahmood Roshan, Asiyeh Habibi, J. Alfonso L. Aguerri +11
This paper examines the reliability of the Tremaine-Weinberg (TW) method in measuring the pattern speed of barred galaxies at high redshifts. Measuring pattern speeds at high redsh…
Search for Slow Bars in Two Barred Galaxies with Nuclear Structures: NGC 6951 and NGC 7716
Yun Hee Lee, Ho Seong Hwang, Virginia Cuomo +9
We investigate two barred galaxies with nuclear structures, NGC 6951 and NGC 7716, to examine whether they host slow bars. Using Gemini/GMOS long-slit spectroscopy, we calculate th…
