25,000 optical fiber positioning robots for next-generation cosmology
Joseph H. Silber, David J. Schlegel, Ricardo Araujo +10
Massively parallel multi-object spectrographs are on the leading edge of cosmology instrumentation. The highly successful Dark Energy Spectroscopic Instrument (DESI) which begun su…
Carnegie Supernova Project-II: Near-infrared spectral diversity and template of Type Ia Supernovae
Jing Lu, Eric Y. Hsiao, Mark M. Phillips +30
We present the largest and most homogeneous collection of near-infrared (NIR) spectra of Type Ia supernovae (SNe Ia): 339 spectra of 98 individual SNe obtained as part of the Carne…
Bump Morphology of the CMAGIC Diagram
L. Aldoroty, L. Wang, P. Hoeflich +38
We apply the color-magnitude intercept calibration method (CMAGIC) to the Nearby Supernova Factory SNe Ia spectrophotometric dataset. The currently existing CMAGIC parameters are t…
The MegaMapper: A Stage-5 Spectroscopic Instrument Concept for the Study of Inflation and Dark Energy
David J. Schlegel, Juna A. Kollmeier, Greg Aldering +86
In this white paper, we present the MegaMapper concept. The MegaMapper is a proposed ground-based experiment to measure Inflation parameters and Dark Energy from galaxy redshifts a…
A Spectroscopic Road Map for Cosmic Frontier: DESI, DESI-II, Stage-5
David J. Schlegel, Simone Ferraro, Greg Aldering +62
In this white paper, we present an experimental road map for spectroscopic experiments beyond DESI. DESI will be a transformative cosmological survey in the 2020s, mapping 40 milli…
A Probabilistic Autoencoder for Type Ia Supernovae Spectral Time Series
George Stein, Uros Seljak, Vanessa Bohm +37
We construct a physically-parameterized probabilistic autoencoder (PAE) to learn the intrinsic diversity of type Ia supernovae (SNe Ia) from a sparse set of spectral time series. T…
