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…
The Changing-look Phenomenon Accompanied by an Accretion Mode Transition in NGC 3786
Suyeon Son, Minjin Kim, Luis C. Ho +2
To reveal the physical origin of the changing-look (CL) phenomenon in NGC 3786, which transitioned from type 1.8/1.9 to type 1, we present an analysis of long-term spectral monitor…
The Identification of Asymmetric Barred Galaxies in Illustris TNG-50
Junwoo Jung, Minjin Kim, Taehyun Kim
Most barred galaxies exhibit symmetric structures. However, recent studies have shown that a subset of barred galaxies exhibit lopsided morphologies. To quantify their occurrence a…
A nuclear disc at Cosmic Noon: evidence of early bar-driven galaxy evolution
Zoe A. Le Conte, Dimitri A. Gadotti, Thomas Harvey +7
Recent studies have revealed that bars can form as early as a few billion years after the Big Bang, already displaying characteristics similar to those of evolved bars in the Local…
The impact of bars on the properties of HII regions in the TIMER survey
Laura Sánchez-Menguiano, Dimitri A. Gadotti, Almudena Zurita +10
In this study we perform a comparative analysis of the properties of the HII regions located in different areas of barred galaxies, with the aim of investigating the impact of bars…
Bar ages derived for the first time in nearby galaxies: Insights on secular evolution from the TIMER sample
Camila de Sá-Freitas, Dimitri A. Gadotti, Francesca Fragkoudi +9
Once galaxies settle their discs and become self-gravitating, stellar bars can form, driving the subsequent evolution of their host galaxy. Determining the ages of bars can therefo…
