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…

The \ion{H}{I}-rich Ultra-diffuse Galaxies follow the Extended Schmidt Law

Sai Zhai, Yong Shi, Zhi-Yu Zhang +7

The \ion{H}{I}-rich ultra-diffuse galaxies (HUDGs) offer a unique case for studies of star formation laws (SFLs) as they host low star formation efficiency (SFE) and low-metallicit…

The Volumetric Extended-Schmidt Law: A Unity Slope

Kaiyi Du, Yong Shi, Zhi-Yu Zhang +5

We investigate the extended-Schmidt (ES) law in volume densities ( ) for spatially-resolved regions in spiral,…

Probing possible effects of circumgalactic media on the metal content of galaxies through the mass-metallicity relationship

Sai Zhai, Yong Shi, Jianhang Chen +4

The circumgalactic medium (CGM) connects the gas between the interstellar medium (ISM) and the intergalactic medium, which plays an important role in galaxy evolution. We use the s…
