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…

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…

Radio Emission from the Infrared Tidal Disruption Event WTP14adeqka: The First Directly Resolved Delayed Outflow from a TDE

Walter W. Golay, Edo Berger, Yvette Cendes +10

We present detailed radio observations of the mid-infrared (MIR) tidal disruption event (TDE) WTP14adeqka. We detect rising radio emission starting years after the disc…

James Webb Space Telescope Observations of the Nearby and Precisely-Localized FRB 20250316A: A Potential Near-IR Counterpart and Implications for the Progenitors of Fast Radio Bursts

Peter K. Blanchard, Edo Berger, Shion E. Andrew +23

We present deep James Webb Space Telescope near-infrared imaging to search for a quiescent or transient counterpart to FRB 20250316A, which was precisely localized with the CHIME/F…
