A Transient "Changing-look'' Active Galactic Nucleus Resolved on Month Timescales from First-year Sloan Digital Sky Survey V Data
Grisha Zeltyn, Benny Trakhtenbrot, Michael Eracleous +32
We report the discovery of a new ``changing-look'' active galactic nucleus (CLAGN) event, in the quasar SDSS J162829.17+432948.5 at z=0.2603, identified through repeat spectroscopy…
The Active Galactic Nuclei in the Hobby-Eberly Telescope Dark Energy Experiment Survey (HETDEX) III. A red quasar with extremely high equivalent widths showing powerful outflows
Chenxu Liu, Karl Gebhardt, Wolfram Kollatschny +12
We report an Active Galactic Nucleus (AGN) with extremely high equivalent width (EW), EW(LyA+NV,rest)>921 AA in the rest-frame, at z~2.24 in the Hobby-Eberly Telescope Dark Energy…
Beyond CDM constraints from the full shape clustering measurements from BOSS and eBOSS
Agne Semenaite, Ariel G. Sánchez, Andrea Pezzotta +7
We analyse the full shape of anisotropic clustering measurements from the extended Baryon Oscillation Spectroscopic survey (eBOSS) quasar sample together with the combined galaxy s…
White dwarf binaries Across the H-R Diagram
Borja Anguiano, Steven R. Majewski, Keivan G. Stassun +7
We created the APOGEE-GALEX-\emph{Gaia} catalog to study white dwarfs binaries. This database aims to create a minimally biased sample of WD binary systems identified from a combin…
The Active Galactic Nuclei in the Hobby-Eberly Telescope Dark Energy Experiment Survey (HETDEX) II. Luminosity Function
Chenxu Liu, Karl Gebhardt, Erin Mentuch Cooper +13
We present the LyA emission line luminosity function (LF) of the Active Galactic Nuclei (AGN) in the first release of the Hobby-Eberly Telescope Dark Energy Experiment Survey (HETD…
Lyα Halos around [O III]-Selected Galaxies in HETDEX
Maja Lujan Niemeyer, William P. Bowman, Robin Ciardullo +13
We present extended Lyman-α (Lyα) emission out to 800 kpc of 1034 [O III]-selected galaxies at redshifts 1.9<z<2.35 using the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX)…
