ZTF SN Ia DR2 follow-up: Characterization of subluminous Type Ia supernovae in the ZTF DR2 full sample

Alaa Alburai, Lluís Galbany, Umut Burgaz +19

The Zwicky Transient Facility Data Release 2 (ZTF DR2) includes a total of 3,628 Type Ia supernovae (SNe~Ia), providing the largest and most complete sample of spectroscopically co…

Near-Infrared Spectroscopy and Detection of Carbon Monoxide in the Type II Supernova SN 2023ixf

Seong Hyun Park, Jeonghee Rho, Sung-Chul Yoon +33

Core-collapse supernovae (CCSNe) may contribute a significant amount of dust in the early universe. Freshly formed coolant molecules (e.g., CO) and warm dust can be found in CCSNe…

Statistical Analysis of Early Spectra in Type II and IIb Supernovae

Maider González-Bañuelos, Claudia P. Gutiérrez, Lluís Galbany +1

We present a comprehensive analysis of the early spectra of type II and type IIb supernovae (SNe) to explore their diversity and distinguishable characteristics. Using 866 publicly…

SN 2023gpw: exploring the diversity and power sources of hydrogen-rich superluminous supernovae

Tuomas Kangas, Panos Charalampopoulos, Takashi Nagao +18

We present our observations and analysis of SN 2023gpw, a hydrogen-rich superluminous supernova (SLSN II) with broad emission lines in its post-peak spectra. Unlike previously obse…

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…

Rapid follow-up observations of infant supernovae with the Gran Telescopio Canarias

Lluís Galbany, Claudia P. Gutiérrez, Lara Piscarreta +21

The first few hours of a supernova (SN) contain significant information about the progenitor system. The most modern wide-field surveys that scan the sky repeatedly every few days…

The Progenitor Systems of Classical Novae in M31

C. S. Abelson, Carles Badenes, Laura Chomiuk +4

We present the first characterization of the statistical relationship between a large sample of novae in M31 and their progenitor stellar populations in the form of a delay time di…
