Not So Heavy Metal I: Low Metallicity Enhances the Rate of high-redshift Superluminous Supernovae
Ben Margalit, Allison L. Strom, Cristina Andrade +4
Type-I superluminous supernovae (SLSNe) are extremely luminous stellar explosions originating from the core collapse of massive stars. Unlike normal core-collapse supernovae, howev…

James Freeburn, Igor Andreoni, Kaylee M. de Soto +55
The Vera C. Rubin Observatory will soon survey the southern sky, delivering a depth and sky coverage that is unprecedented in time domain astronomy. As part of commissioning, Data…
The Effect of Vera C. Rubin Observatory Cadence Selections on Kilonova Detectability
Cristina Andrade, Raiyah Alserkal, Luis Salazar Manzano +5
The discovery of the optical/infra-red counterpart (AT2017gfo) to the binary neutron star gravitational-wave detection (GW170817), which was followed by a short gamma-ray burst (GR…
Early-Time Observations of SN 2023wrk: A Luminous Type Ia Supernova with Significant Unburned Carbon in the Outer Ejecta
Jialian Liu, Xiaofeng Wang, Cristina Andrade +44
We present extensive photometric and spectroscopic observations of the nearby Type Ia supernova (SN) 2023wrk at a distance of about 40 Mpc. The earliest detection of this SN can be…
