Chemical Compositions of Red Giant Stars from Habitable Zone Planet Finder Spectroscopy
Christopher Sneden, Melike Afsar, Zeynep Bozkurt +15
We have used the Habitable Zone Planet Finder (HPF) to gather high resolution, high signal-to-noise near-infrared spectra of 13 field red horizontal-branch (RHB) stars, one open-cl…
Constraining the quasar radio-loud fraction at with deep radio observations
Yuanqi Liu, Ran Wang, Emmanuel Momjian +8
We carry out a series of deep Karl G. Jansky Very Large Array (VLA) S-band observations of a sample of 21 quasars at . The new observations expand the searches of radio con…
Cosmological 3D HI Gas Map with HETDEX Ly Emitters and eBOSS QSOs at : IGM-Galaxy/QSO Connection and a 40-Mpc Scale Giant HII Bubble Candidate
Shiro Mukae, Masami Ouchi, Gary J. Hill +20
We present cosmological ( Mpc) distributions of neutral hydrogen (HI) in the inter-galactic medium (IGM) traced by Ly Emitters (LAEs) and QSOs at , selected w…
The Energetics of Launching the Most Powerful Jets in Quasars: A Study of 3C82
Brian Punsly, Gary J. Hill, Paola Marziani +5
3C 82 at a redshift of 2.87 is the most distant 3C (Third Cambridge Catalogue) quasar. Thus, it is a strong candidate to have the most luminous radio lobes in the Universe. 3C 82 b…
MCSED: A flexible spectral energy distribution fitting code and its application to emission-line galaxies
William P. Bowman, Gregory R. Zeimann, Gautam Nagaraj +7
We present MCSED, a new spectral energy distribution (SED)-fitting code, which mates flexible stellar evolution calculations with the Markov Chain Monte Carlo algorithms of the sof…
