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…

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…

Optimising the analysis of emission lines in galaxies: the case of the MUSE TIMER galaxy NGC 613

Luiz A. Silva-Lima, Dimitri A. Gadotti, Lucimara P. Martins +11

Galaxy evolution is driven by spatially distributed processes with varying timescales. Integral field spectroscopy provides spatially-resolved information about these processes. Ne…

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…

The universal variability of the stellar initial mass function probed by the TIMER survey

Ignacio Martín-Navarro, Adriana de Lorenzo-Cáceres, Dimitri A. Gadotti +7

The debate about the universality of the stellar initial mass function (IMF) revolves around two competing lines of evidence. While measurements in the Milky Way, an archetypal spi…

Central enhancement of the nitrogen-to-oxygen abundance ratio in barred galaxies

E. Florido, A. Zurita, I. Perez +3

Bar-induced gas inflows towards the galaxy centres are recognized as a key agent for the secular evolution of galaxies. One immediate consequence is the accumulation of gas in the…
