Spectroscopic Analysis of Fermi-detected Blazars using SDSS-V
Mohammed Iddrisu Nlowie, James Aird, Eli Kasai +17
The paper introduces a multi-component spectral fitting pipeline applied to SDSS‑V spectra of Fermi‑detected blazars, reclassifying many misidentified sources, improving redshift e…
HETDEX: Star Formation Stochasticity Diagram of Lyman Alpha Emitting Galaxies at Cosmic Noon Confirms Three Archetypes
Nicole Firestone, Eric Gawiser, Kartheik G. Iyer +14
In this work, we aim to measure the star formation stochasticity of Lyman Alpha Emitting Galaxies (LAEs) at Cosmic Noon. We identify 270 LAEs from the HETDEX Survey in the COSMOS f…
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…
HETDEX [OII] galaxies at : Volume-limited samples and their power spectra
Jeongin Moon, Eiichiro Komatsu, Robin Ciardullo +15
The catalog from the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) Public Data Release 1 (PDR1) contains half a million emission-line-selected [OII] galaxies spread across…
There is no single density: star-forming regions and galaxies hold more dense ionized gas than long assumed
J. Eduardo Méndez-Delgado, Christophe Morisset, William J. Henney +29
Ionized gas fills star-forming regions and galaxies, and nearly everything we know about its temperature, pressure, mass, and composition is inferred from its emission lines [1-3].…
A New Member of the Fast and Furious Family: A Relativistic and Time-Variable UV Outflow in a Luminous Quasar
Lucas M. Seaton, Patrick B. Hall, Liliana Flores +20
We report the fastest quasar outflow first detected in the ultraviolet, via variable C IV and Si IV absorption at outflow velocities km s to at least km…
