Radio-detected Lya emitters at 1.88 < z < 3.52: AGN fraction and Lya emission
Sai Zhai, Huub Röttgering, Anniek J. Gloudemans +10
Lya emitters (LAEs) are galaxies with strong Lya emission, tracing early star formation and ionizing radiation. Their connection to active galactic nuclei (AGNs) is key to understa…

Lyα Nebulae in HETDEX: The Largest Statistical Census Bridging Lyα Halos and Blobs across Cosmic Noon
Erin Mentuch Cooper, Karl Gebhardt, Dustin Davis +20
The Hobby-Eberly Dark Energy Experiment (HETDEX) is an untargeted ~540 deg^2 spectroscopic survey of Lyα emission in the 1.9 < z < 3.5 Universe. In surface brightness, this survey…

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…
