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…

Observations of a Possible Transient Magnetically Arrested Accretion State in a Nearby Quasar: OQ208

Brian Punsly, Cormac Reynolds, Paola Marziani +12

OQ208 is a nearby, partially obscured quasar (z=0.077) that is a young, bright, parsec scale radio source. We assemble archival and new high frequency VLBA and VLA observations and…

Using Mg II Doublet to Predict the Lyman Continuum Escape Fraction from 14 HETDEX Galaxies

Victoria Salazar, Floriane Leclercq, John Chisholm +2

Indirect diagnostics of Lyman continuum (LyC) escape are needed to constrain which sources reionized the universe. We used Mg II to predict the LyC escape fraction (fesc(LyC)) in 1…
