The Equivalent Width as an Ionization-Parameter Diagnostic Across Cosmic Time
Dian P. Triani, Lisa J. Kewley
Nebular emission lines and stellar continua probe the conditions of regions. The optical emission line is important because it is observab…
The CEERS Photometric and Physical Parameter Catalog
Isa G. Cox, Jeyhan S. Kartaltepe, Micaela B. Bagley +35
We present the Cosmic Evolution Early Release Science Survey (CEERS) catalog, including space-based photometry, photometric redshifts, and physical parameters for more than 80,000…
CEERS: Forging the First Dust Grains in the Universe? A Population of Galaxies with spectroscopically-derived Extremely Low Dust Attenuation (GELDA) at 4.0<z<11.4
Denis Burgarella, Véronique Buat, Patrice Theulé +35
We investigate the coevolution of metals and dust in 173 galaxies at using NIRSpec spectroscopy. Focusing on galaxies with extremely low dust attenuation, we explore t…
The Cosmic Evolution Early Release Science Survey (CEERS)
Steven L. Finkelstein, Micaela B. Bagley, Pablo Arrabal Haro +96
We present the Cosmic Evolution Early Release Science (CEERS) Survey, a 77.2 hour Director's Discretionary Early Release Science Program. CEERS demonstrates, tests, and validates e…
Theoretical Diagnostics for Narrow Line Regions of Active Galactic Nuclei
Peixin Zhu, Lisa J. Kewley, Ralph Sutherland
Gas metallicity, ionization parameter, and gas pressure can affect the observed ratios of specific strong emission lines within galaxies. While the theoretical strong lines diagnos…
CEERS: Forging the First Dust -- Transition from Stellar to ISM Grain Growth in the Early Universe
Denis Burgarella, Véronique Buat, Patrice Theulé +36
We investigate the coevolution of metals and dust for 173 galaxies at 4.0<z<11.4 observed with JWST/NIRSpec. We use the code CIGALE that integrates photometric and spectroscopic da…
