Aarmed with Data: Bumps, Outflows, and Disk-like Emission in TDE 2025aarm

Aysha Aamer, Kate D. Alexander, Charlotte R. Angus +42

The origin of the optical emission in tidal disruption events (TDEs) remains one of the major outstanding questions in the field, in part due to the limited number of nearby events…

Dust Without Na I D Trace: The Case of Highly Attenuated Type Ib SN 2024vjc

Javier Silva-Farfán, Keiichi Maeda, Andrea Pastorello +19

Understanding dust attenuation toward extragalactic transients is critical for recovering their intrinsic properties and probing the local environments of distant galaxies. A popul…

Early Near-Infrared Excess and Rapid Disk-Corona Evolution in the Tidal Disruption Event 2024aepd

Yongxin Wu, Yanan Wang, Thomas M. Reynolds +38

We present multi-wavelength observations of the tidal disruption event (TDE) 2024aepd, spanning primarily the first 300 days after discovery. The X-ray spectrum is initially…

Evidence for Asymmetric Ejecta and Circumstellar Material in SN 2023ixf Inferred from Extensive Nebular-phase Observations

Brian Hsu, Nathan Smith, K. Azalee Bostroem +34

We present extensive optical and near-infrared (NIR) observations of the nearby Type II supernova (SN II) 2023ixf in the nebular phase from +89 days to +749 days after explosion, s…

SN 2020bij and a Possible Slow-Rise High-Velocity Subclass of Type IIP Supernovae

Sondos Mohsen-Tanev, Iair Arcavi, Shahar Bracha +17

Mapping how the explosion properties of Type II supernovae (SNe II) relate to the properties of their progenitors can provide strong constraints for understanding the final evoluti…

The Type I Superluminous Supernova Catalogue II: Spectroscopic Evolution in the Photospheric Phase, Velocity Measurements, and Constraints on Diversity

Aysha Aamer, Matt Nicholl, Sebastian Gomez +29

Hydrogen-poor superluminous supernovae (SLSNe) are among the most energetic explosions in the universe, reaching luminosities up to 100 times greater than those of normal supernova…
