On the Detection of Supermassive Primordial Stars
Marco Surace, Daniel J. Whalen, Tilman Hartwig +6
The collapse of supermassive primordial stars in hot, atomically-cooled halos may have given birth to the first quasars at 15 - 20. Recent numerical simulations of these r…
The case for gravitational millilensing in the multiply--imaged quasar B1152+199
Saghar Asadi, Erik Zackrisson, Eskil Varenius +3
Previous Very Long Baseline Interferometry (VLBI) observations of the quasar B1152+199 at 5GHz has revealed two images of a strongly lensed jet with seemingly discordant morphologi…
Detection of the Far-infrared [O III] and Dust Emission in a Galaxy at Redshift 8.312: Early Metal Enrichment in the Heart of the Reionization Era
Yoichi Tamura, Ken Mawatari, Takuya Hashimoto +19
We present the Atacama Large Millimeter/submillimeter Array (ALMA) detection of the [O III] 88 m line and rest-frame 90 m dust continuum emission in a Y-dropout Lyman break g…
"Big Three Dragons": a z = 7.15 Lyman BreakGalaxy Detected in [OIII] 88 m, [CII] 158 m, and Dust Continuum with ALMA
Takuya Hashimoto, Akio K. Inoue, Ken Mawatari +18
We present new ALMA observations and physical properties of a Lyman Break Galaxy at z=7.15. Our target, B14-65666, has a bright ultra-violet (UV) absolute magnitude, $M_{\rm UV}\ap…
The onset of star formation 250 million years after the Big Bang
Takuya Hashimoto, Nicolas Laporte, Ken Mawatari +21
A fundamental quest of modern astronomy is to locate the earliest galaxies and study how they influenced the intergalactic medium a few hundred million years after the Big Bang. Th…
Reionization in Technicolor
Kristian Finlator, Laura Keating, Benjamin D. Oppenheimer +2
We present the Technicolor Dawn simulations, a suite of cosmological radiation-hydrodynamic simulations of the first 1.2 billion years. By modeling a spatially-inhomogeneous UVB on…
