Metal and dust evolution in ALMA REBELS galaxies: insights for future JWST observations

Marco Palla, Ilse De Looze, Monica Relaño +16

ALMA observations revealed the presence of significant amounts of dust in the first Gyr of Cosmic time. However, the metal and dust buildup picture remains very uncertain due to th…

Stellar mass-metallicity relation throughout the large-scale structure of the Universe: CAVITY mother sample

Jesús Domínguez-Gómez, Isabel Pérez, Tomás Ruiz-Lara +21

Void galaxies are essential for understanding the physical processes that drive galaxy evolution because they are less affected by external factors than galaxies in denser environm…

ALMA Lensing Cluster Survey: average dust, gas, and star formation properties of cluster and field galaxies from stacking analysis

Andrea Guerrero, Neil Nagar, Kotaro Kohno +18

We develop new tools for continuum and spectral stacking of ALMA data, and apply these to the ALMA Lensing Cluster Survey (ALCS). We derive average dust masses, gas masses and star…

Revealing the structure of the lensed quasar Q 0957+561 III. Constraints on the size of the broad-line region

C. Fian, J. A. Muñoz, E. Mediavilla +6

Our aim is to examine the size, kinematics, and geometry of the broad-line region (BLR) in the double-lensed quasar Q 0957+561 by analyzing the impact of microlensing on various re…

Galaxies in voids assemble their stars slowly

J. Domínguez-Gómez, I. Pérez, T. Ruiz-Lara +20

Galaxies in the Universe are distributed in a web-like structure characterised by different large-scale environments: dense clusters, elongated filaments, sheetlike walls, and unde…

Observations and chemical modeling of the isotopologues of formaldehyde and the cations of formyl and protonated formaldehyde in the hot molecular core G331.512-0.103

Edgar Mendoza, Miguel Carvajal, Manuel Merello +2

In the interstellar cold gas, the chemistry of formaldehyde (HCO) can be essential to explain the formation of complex organic molecules. On this matter, the massive and energe…

ED-2: a cold but not so narrow stellar stream crossing the Solar neighbourhood

E. Balbinot, A. Helmi, T. Callingham +3

ED-2 is a stellar stream identified as a compact group in integrals of motion space in a local sample of halo stars from the third Gaia data release. Here we investigate its nature…

On the origin of the Galactic thin and thick discs, their abundance gradients and the diagnostic potential of their abundance ratios

Nikos Prantzos, Carlos Abia, Tianxiang Chen +8

Using a semi-analytical model of the evolution of the Milky Way, we show how secular evolution can create distinct overdensities in the phase space of various properties (e.g. age…

Integral Field Spectroscopy of the Cometary Starburst Galaxy NGC 4861

Nathan Roche, José M. Vílchez, Jorge Iglesias-Páramo +4

Using the PMAS Integral Field Unit on the Calar Alto 3.5m telescope we observed the southern component (Markarian 59) of the `cometary' starburst galaxy NGC 4861. Mrk 59 is centred…

Molecular gas in super spiral galaxies

Ute Lisenfeld, Patrick M. Ogle, Philip N. Appleton +2

At the highest stellar masses (log(\mstar) 11.5 \msun), only a small fraction of galaxies are disk-like and actively star-forming objects. These so-called `super spirals'…
