Bulgeless Evolution And the Rise of Discs (BEARD) I. Physical drivers of the mass-size relation for Milky Way-like galaxies
C. Marrero-de la Rosa, J. Méndez-Abreu, A. de Lorenzo-Cáceres +20
In the standard cold dark matter (CDM) cosmology, the existence of massive pure-disc galaxies remains challenging within the hierarchical framework and is key to understandi…
Bulgeless Evolution And the Rise of Discs (BEARD) II. The role of mergers in shaping the Milky Way analogues in TNG50
Yetli Rosas-Guevara, Jairo Méndez-Abreu, Adriana de Lorenzo-Cáceres +20
We study the formation and evolution of bulgeless galaxies within the Milky Way-Andromeda analogue sample of the TNG50 simulation. Through kinematic decomposition with Mordor, we i…

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…
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 dynamical state of bars in cluster dwarf galaxies: The cases of NGC 4483 and NGC 4516
V. Cuomo, L. Morelli, J. A. L. Aguerri +13
Dwarf barred galaxies are the perfect candidates for hosting slowly-rotating bars. They are common in dense environments and they have a relatively shallow potential well, making t…
A Milky Way-like barred spiral galaxy at a redshift of 3
Luca Costantin, Pablo G. Pérez-González, Yuchen Guo +30
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 dynam…
Disc galaxies are still settling: The discovery of the smallest nuclear discs and their young stellar bars
Camila de Sá-Freitas, Dimitri A. Gadotti, Francesca Fragkoudi +11
When galactic discs settle and become massive enough, they are able to form stellar bars. These non-axisymmetric structures induce shocks in the gas, causing it to flow to the cent…
Composite Bulges -- III. A Study of Nuclear Star Clusters in Nearby Spiral Galaxies
Aishwarya Ashok, Anil Seth, Peter Erwin +17
We present photometric and morphological analyses of nuclear star clusters (NSCs) -- very dense, massive star clusters present in the central regions of most galaxies -- in a sampl…
A new method for age-dating the formation of bars in disc galaxies: The TIMER view on NGC1433's old bar and the inside-out growth of its nuclear disc
Camila de Sá-Freitas, Francesca Fragkoudi, Dimitri A. Gadotti +16
The epoch in which galactic discs settle is a major benchmark to test models of galaxy formation and evolution but is as yet largely unknown. Once discs settle and become self-grav…
Spatially-resolved properties of the ionized gas in the HII galaxy J084220+115000
D. Fernández-Arenas, E. Carrasco, R. Terlevich +20
We present a spatially resolved spectroscopic study for the metal poor HII galaxy J084220+115000 using MEGARA Integral Field Unit observations at the Gran Telescopio Canarias. We e…
Forecasting the success of the WEAVE Wide-Field Cluster Survey on the extraction of the cosmic web filaments around galaxy clusters
Daniel J. Cornwell, Ulrike Kuchner, Alfonso Aragón-Salamanca +7
Next-generation wide-field spectroscopic surveys will observe the infall regions around large numbers of galaxy clusters with high sampling rates for the first time. Here we assess…
From naked spheroids to disky galaxies: how do massive disk galaxies shape their morphology?
L. Costantin, P. G. Pérez-González, J. Méndez-Abreu +9
We investigate the assembly history of massive disk galaxies and describe how they shape their morphology through cosmic time. Using SHARDS and HST data, we modeled the surface bri…
The origin of bulges and discs in the CALIFA survey: I. Morphological evolution
J. Mendez-Abreu, A. de Lorenzo-Caceres, S. F. Sanchez
This series of papers aims at understanding the formation and evolution of non-barred disc galaxies. We use the new spectro-photometric decomposition code, C2D, to separate the spe…
A duality in the origin of bulges and spheroidal galaxies
L. Costantin, P. G. Pérez-González, J. Méndez-Abreu +11
Studying the resolved stellar populations of the different structural components which build massive galaxies directly unveils their assembly history. We aim at characterizing the…
Bar pattern speeds in CALIFA galaxies III. Solving the puzzle of ultrafast bars
Virginia Cuomo, Yun Hee Lee, Chiara Buttitta +3
More than 10% of the barred galaxies with a direct measurement of the bar pattern speed host an ultrafast bar. These bars extend beyond the corotation radius and challenge our unde…
