Composite Bulges -- V. Detecting signatures of gas inflows in IFU data: The MUSE view of ionised gas kinematics in nearby galaxies

Tutku Kolcu, Witold Maciejewski, Peter Erwin +7

Using VLT/MUSE data, we study the ionised-gas kinematics in a mass- and volume-limited (, \,Mpc) sample of 21 nearby galaxies to identify signa…

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…

Robust galaxy image decompositions with Differential Evolution optimisation and the problem of classical bulges in and beyond the nearby Universe

Dimitri A. Gadotti

Deconstructing galaxies through two-dimensional decompositions has been shown to be a powerful technique to derive the physical properties of stellar structures in galaxies. Howeve…

The evolution of the bar fraction and bar lengths in the last 12 billion years

Zoe A. Le Conte, Dimitri A. Gadotti, Leonardo Ferreira +7

We investigate the evolution of the bar fraction and length using an extended JWST NIRCam imaging dataset of galaxies at . We assess the wavelength dependence of t…
