Free Neutron Decay in Kilonova Ejecta: X-ray/UV Flashes with Non-Thermal Effects

Daniel Brethauer, Daniel Kasen, Smaranika Banerjee +2

Neutron star-bearing compact-object mergers can create a kilonova, a transient powered by the radioactive decay of material synthesized via rapid neutron capture (-process). Dur…

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.…

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…

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…

Rubin ToO 2024: Envisioning the Vera C. Rubin Observatory LSST Target of Opportunity program

Igor Andreoni, Raffaella Margutti, John Banovetz +86

The Legacy Survey of Space and Time (LSST) at Vera C. Rubin Observatory is planned to begin in the Fall of 2025. The LSST survey cadence has been designed via a community-driven pr…

Impact of Systematic Modeling Uncertainties on Kilonova Property Estimation

Daniel Brethauer, Daniel Kasen, Raffaella Margutti +1

The precise atomic structure and therefore the wavelength-dependent opacities of lanthanides are highly uncertain. This uncertainty introduces systematic errors in modeling transie…
