Euclid: Field-level inference of primordial non-Gaussianity and cosmic initial conditions

A. Andrews, J. Jasche, G. Lavaux +147

A primary target of the \Euclid space mission is to constrain early-universe physics by searching for deviations from a primordial Gaussian random field. A significant detection of…

Behind the dust veil: A panchromatic view of an optically dark galaxy at z=4.82

Nikolaj B. Sillassen, Shuowen Jin, Georgios E. Magdis +30

Optically dark dusty star-forming galaxies (DSFGs) play an essential role in massive galaxy formation at early cosmic time, however their nature remains elusive. Here we present a…

Yields from massive stars in binaries. Chemical evolution of the Milky Way disk

E. Pepe, M. Palla, F. Matteucci +1

A large fraction of massive stars in the Galaxy reside in binary systems and their evolution is different from that of single stars. The yields of massive stars, which are the main…

The radio properties of the JWST-discovered AGN

G. Mazzolari, R. Gilli, R. Maiolino +23

We explore the radio emission of JWST-selected Broad Line AGN (BLAGN, or type 1) in the GOODS-N field. We use deep radio data at different frequencies (144\,MHz, 1.5\,GHz, 3\,GHz,…

Optical monitoring in southern blazars. Analysis of variability and spectral colour behaviours

L. Zibecchi, I. Andruchow, E. Ej. Marchesini +2

We present the results of the optical monitoring of 18 southern blazars in the V and R Johnson-Cousins bands. Our main objective is to study the variations in the optical flux and…

WEAVE First Light Observations: Origin and Dynamics of the Shock Front in Stephan's Quintet

M. I. Arnaudova, S. Das, D. J. B. Smith +62

We present a detailed study of the large-scale shock front in Stephan's Quintet, a byproduct of past and ongoing interactions. Using integral-field spectroscopy from the new Willia…
