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…
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…
Roaring to softly whispering: Persistent X-ray emission at the location of the Fast Blue Optical Transient AT2018cow 3.7 yrs after discovery and implications on accretion-powered scenarios
G. Migliori, R. Margutti, B. D. Metzger +11
We present the first deep X-ray observations of a luminous FBOT AT2018cow, at since discovery, together with the re-analysis of the observation at d…
SN 2023ixf in Messier 101: Photo-ionization of Dense, Close-in Circumstellar Material in a Nearby Type II Supernova
W. V. Jacobson-Galan, L. Dessart, R. Margutti +65
We present UV/optical observations and models of supernova (SN) 2023ixf, a type II SN located in Messier 101 at 6.9 Mpc. Early-time ("flash") spectroscopy of SN 2023ixf, obtained p…
