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 Euclid statistical study of the active galactic nuclei contribution fraction

Euclid Collaboration, B. Margalef-Bentabol, L. Wang +331

Active galactic nuclei (AGN) play a key role in galaxy evolution but are challenging to identify due to their varied observational signatures. Furthermore, understanding their impa…

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…

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…

The evolution of extragalactic peaked-spectrum sources down to 54 megahertz

Sai Zhai, Anniek J. Gloudemans, Gülay Gürkan +4

Peaked-spectrum (PS) sources, known for their distinct peaked radio spectra, represent a type of radio-loud active galactic nuclei (AGN). Among these, megahertz-peaked spectrum (MP…
