2D End-to-End Modeling of Kilonovae from Binary Neutron Star Merger Remnants
Lieke Sippens Groenewegen, Sanjana Curtis, Philipp Mösta +2
We investigate the kilonova emission resulting from outflows produced in a three-dimensional (3D) general-relativistic magnetohydrodynamic (GRMHD) simulation of a hypermassive neut…
Non-Thermal Ionization of Kilonova Ejecta: Observable Impacts
Daniel Brethauer, Daniel Kasen, Raffaella Margutti +1
The characteristic rapid rise and decline at optical wavelengths of a kilonova is the product of the low ejecta mass () and high ejecta velocity ($\gtrsim 0.…
Evidence for Extended Hydrogen-Poor CSM in the Three-Peaked Light Curve of Stripped Envelope Ib Supernova
Yossef Zenati, Qinan Wang, Alexey Bobrick +40
We present multi-band ATLAS photometry for SN 2019tsf, a stripped-envelope Type Ib supernova (SESN). The SN shows a triple-peaked light curve and a late (re-)brightening, making it…
The La Silla Schmidt Southern Survey
Adam A. Miller, Natasha S. Abrams, Greg Aldering +75
We present the La Silla Schmidt Southern Survey (LS4), a new wide-field, time-domain survey to be conducted with the 1 m ESO Schmidt telescope. The 268 megapixel LS4 camera mosaics…
