Euclid Quick Data Release (Q1). Extending the quest for little red dots to z<4
Euclid Collaboration, L. Bisigello, G. Rodighiero +348
Recent James Webb Space Telescope (JWST) observations have revealed a population of sources with a compact morphology and a characteristic `v-shaped' continuum, namely blue at rest…
Non-thermal filaments and AGN recurrent activity in the galaxy group Nest200047: a LOFAR, uGMRT, MeerKAT, VLA radio spectral analysis
M. Brienza, K. Rajpurohit, E. Churazov +15
Nest200047 is a clear example of multiple radio bubbles from an Active Galactic Nucleus (AGN) in a galaxy group, featuring non-thermal filaments likely shaped by buoyancy, gas moti…
SEMPER I. Radio Predictions for Star-Forming Galaxies at
M. Giulietti, I. Prandoni, M. Bonato +7
[Abridged] SFGs are the dominant population in the faint radio sky, corresponding to flux densities at 1.4 GHz mJy. A panchromatic approach is essential for selecting SFGs…
Euclid Quick Data Release (Q1) First study of red quasars selection
Euclid Collaboration, F. Tarsitano, S. Fotopoulou +322
Red quasars constitute an important but elusive phase in the evolution of supermassive black holes, where dust obscuration can significantly alter their observed properties. They h…
Euclid Quick Data Release (Q1) Exploring galaxy properties with a multi-modal foundation model
Euclid Collaboration, M. Siudek, M. Huertas-Company +321
Modern astronomical surveys, such as the Euclid mission, produce high-dimensional, multi-modal data sets that include imaging and spectroscopic information for millions of galaxies…
The environments of radio galaxies and quasars in LoTSS data release 2
Tong Pan, Yuming Fu, H. J. A. Rottgering +4
Aims. The orientation-based unification scheme of radio-loud active galactic nuclei (AGNs) asserts that radio galaxies and quasars are essentially the same type of object, but view…
