HARMONI@ELT: instrument design, performance, and science capabilities
B. Neichel, J. Dunlop, S. Chittick +17
The paper describes the design, performance expectations, and scientific capabilities of HARMONI, the near‑infrared integral field spectrograph being built for the Extremely Large…
How large can galaxies be? Ultra-deep imaging of IC 1101, the most extended known galaxy
Carlos Marrero-de la Rosa, Ignacio Trujillo, Ignacio Ruiz Cejudo +18
The maximum physical extent that galaxies can reach is poorly understood. In this regard, IC 1101, one of the most extended and massive galaxies known, provides a valuable opportun…
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…
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 understan…
Bulgeless Evolution And the Rise of Discs (BEARD) III. A numerical simulation view of satellites around Milky-Way analogues
Salvador Cardona-Barrero, Jairo Méndez-Abreu, Adriana de Lorenzo-Cáceres +17
. The existence of massive disc galaxies with little or no bulge challenges conventional cold dark matter model, which typically favours dynamically hot central structur…
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…
