The Growing Importance of a Tech Savvy Astronomy and Astrophysics Workforce
Dara Norman, Kelle Cruz, Vandana Desai +26
Fundamental coding and software development skills are increasingly necessary for success in nearly every aspect of astronomical and astrophysical research as large surveys and hig…
Astro2020 Science White Paper: Discovery Frontiers of Explosive Transients - An ELT & LSST Perspective
Melissa L. Graham, Danny Milisavljevic, Armin Rest +17
The Large Synoptic Survey Telescope (LSST) will open a discovery frontier for faint and fast transients with its ability to detect variable flux components down to 24.5 mag i…
RAPID: Early Classification of Explosive Transients using Deep Learning
Daniel Muthukrishna, Gautham Narayan, Kaisey S. Mandel +2
We present RAPID (Real-time Automated Photometric IDentification), a novel time-series classification tool capable of automatically identifying transients from within a day of the…
The Next Generation of Cosmological Measurements with Type Ia Supernovae
Dan Scolnic, Saul Perlmutter, Greg Aldering +56
While Type Ia Supernovae (SNe Ia) are one of the most mature cosmological probes, the next era promises to be extremely exciting in the number of different ways SNe Ia are used to…
Cyberinfrastructure Requirements to Enhance Multi-messenger Astrophysics
Philip Chang, Gabrielle Allen, Warren Anderson +39
The identification of the electromagnetic counterpart of the gravitational wave event, GW170817, and discovery of neutrinos and gamma-rays from TXS 0506+056 heralded the new era of…
Gravity and Light: Combining Gravitational Wave and Electromagnetic Observations in the 2020s
R. J. Foley, K. D. Alexander, I. Andreoni +110
As of today, we have directly detected exactly one source in both gravitational waves (GWs) and electromagnetic (EM) radiation, the binary neutron star merger GW170817, its associa…
Models and Simulations for the Photometric LSST Astronomical Time Series Classification Challenge (PLAsTiCC)
R. Kessler, G. Narayan, A. Avelino +26
We describe the simulated data sample for the "Photometric LSST Astronomical Time Series Classification Challenge" (PLAsTiCC), a publicly available challenge to classify transient…
Photometry and spectroscopy of faint candidate spectrophotometric standard DA white dwarfs
A. Calamida, T. Matheson, A. Saha +14
We present precise photometry and spectroscopy for 23 candidate spectrophotometric standard white dwarfs. The selected stars are distributed in the Northern hemisphere and around t…
Constraining Type Iax Supernova Progenitor Systems with Stellar Population Aging
Tyler Takaro, Ryan J. Foley, Curtis McCully +6
Type Iax supernovae (SNe~Iax) are the most common class of peculiar SNe. While they are thought to be thermonuclear white-dwarf (WD) SNe, SNe~Iax are observationally similar to, bu…
