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 "Dark-Matter Dominated" Galaxy Segue 1 Modeled with a Black Hole and no Dark Halo
Nathaniel Lujan, Karl Gebhardt, Richard Anantua +11
The dwarf spheroidal galaxy, Segue 1, is thought to have one of the largest ratios of dark matter to stellar mass. Using orbit-based dynamical models, we model Segue 1, including a…
HETDEX-LOFAR Spectroscopic Redshift Catalog
Maya H. Debski, Gregory R. Zeimann, Gary J. Hill +8
We combine the power of blind integral field spectroscopy from the Hobby-Eberly Telescope (HET) Dark Energy Experiment (HETDEX) with sources detected by the Low Frequency Array (LO…
