Metal-Poor Stars Observed with the Southern African Large Telescope
Kaitlin C. Rasmussen, Joseph Zepeda, Timothy C. Beers +5
We present the first release of a large-scale study of relatively bright (V < 13.5) metal-poor stars observed with the Southern African Large Telescope (SALT), based on high-resolu…
Dual supermassive black holes at close separation revealed by the Hyper Suprime-Cam Subaru Strategic Program
John D. Silverman, Shenli Tang, Khee-Gan Lee +30
The unique combination of superb spatial resolution, wide-area coverage, and deep depth of the optical imaging from the Hyper Suprime-Cam (HSC) Subaru Strategic Program is utilized…
Neural Networks Fail to Learn Periodic Functions and How to Fix It
Liu Ziyin, Tilman Hartwig, Masahito Ueda
Previous literature offers limited clues on how to learn a periodic function using modern neural networks. We start with a study of the extrapolation properties of neural networks;…
Implications of inhomogeneous metal mixing for stellar archaeology
Yuta Tarumi, Tilman Hartwig, Mattis Magg
The first supernovae enrich the previously pristine gas with metals, out of which the next generation of stars form. Based on hydrodynamical simulations, we develop a new stochasti…
Radio Power from a Direct-Collapse Black Hole in CR7
Daniel J. Whalen, Mar Mezcua, Avery Meiksin +2
The leading contenders for the seeds of the first quasars are direct collapse black holes (DCBHs) formed during catastrophic baryon collapse in atomically-cooled halos at …
