The Local Origin of a Host Dispersion Measure-Stellar Mass Relation in Fast Radio Bursts

Wasundara Athukoralalage, Liam Connor, Peter K. Blanchard +1

The origin of fast radio bursts (FRBs) and the relationship to their host galaxy environments remain open questions. Using a sample of 37 FRBs with secure host associations at $z \…

EP241217a: a likely Type II GRB with an achromatic bump at z = 4.59

Hao Zhou, Jia Ren, Chen-Wei Wang +22

EP241217a is an X-ray transient detected by the Einstein Probe (EP) lasting for about 100 seconds and without accompanying -ray detection. The optical spectroscopy reveals the r…

SN 2024afav: A Superluminous Supernova with Multiple Light Curve Bumps and Spectroscopic Signatures of Circumstellar Interaction

Harsh Kumar, Peter K. Blanchard, Edo Berger +8

We present a comprehensive optical and near-infrared spectroscopic study of SN 2024afav - a hydrogen-poor superluminous supernova (SLSN-I) that peaks at -20.7 mag and exh…

Hydrogen-Poor Superluminous Supernovae in the Nebular Phase: Spectral Diversity Due to Ejecta Ionization as a Probe of the Power Source

Peter K. Blanchard, Edo Berger, Sebastian Gomez +6

We present a large sample of 39 nebular-phase optical spectra of 25 hydrogen-poor superluminous supernovae (SLSNe-I) and jointly analyze them with previously published spectra of 1…

When IIb Ceases To Be: Bridging the Gap Between IIb and Short-plateau Supernovae

Joseph R. Farah, D. Andrew Howell, Daichi Hiramatsu +13

Hydrogen-rich supernovae (SNe) span a range of hydrogen envelope masses at core collapse, producing diverse light curves from extended plateaus in Type II SNe to double-peaked Type…

Lense-Thirring precessing magnetar engine drives a superluminous supernova

Joseph R. Farah, Logan J. Prust, D. Andrew Howell +10

Type I superluminous supernovae (SLSNe-I) are at least an order of magnitude brighter than standard supernovae, with the internal power source for their luminosity still unknown. T…
