The Type II SN 2024ggi is one of the nearest core-collapse SNe to have exploded in recent decades. Its proximity has enabled extensive multiwavelength monitoring from early times t…
Light-Curve and Spectral Properties of Type II Supernovae from the ATLAS survey
K. Ertini, J. P. Anderson, G. Folatelli +22
Type II supernovae (SNe II) are the most common terminal stellar explosions in the Universe. With SNe now being detected within days after explosion, there is growing evidence that…
The nebular phase of SN 2024ggi: a low-mass progenitor with no signs of interaction
L. Ferrari, G. Folatelli, K. Ertini +14
Context: SN 2024ggi is a Type II supernova (SN) discovered in the nearby galaxy NGC 3621 (D Mpc) on 2024 April 03.21 UT. Its proximity enabled a detailed investi…
Final Moments III: Explosion Properties and Progenitor Constraints of CSM-Interacting Type II Supernovae
W. V. Jacobson-Galán, L. Dessart, K. W. Davis +52
We present analysis of the plateau and late-time phase properties of a sample of 39 Type II supernovae (SNe II) that show narrow, transient, high-ionization emission lines (i.e., "…
A magnetar powers the luminous supernova 2023pel, associated with a long gamma-ray burst
L. M. Roman Aguilar, M. M. Saez, K. Ertini +1
We explore SN 2023pel, the most recent event associated with gamma-ray bursts (GRBs), specifically GRB 230812B. SN 2023pel has a high luminosity and low expansion velocities compar…
SN 2024ggi: another year, another striking Type II supernova
K. Ertini, T. A. Regna, L. Ferrari +19
SN 2024ggi is a Type II supernova that exploded in the nearby galaxy NGC 3621 at a distance of approximately 7 Mpc, making it one of the closest supernovae of the decade. This SN s…
SN 2023ixf: interaction signatures in the spectrum at 445 days
Gastón Folatelli, Lucía Ferrari, Keila Ertini +2
SN 2023ixf is one of the most neaby and brightest Type II supernovae (SNe) of the past decades. A rich set of pre-explosion data provided important insight on the properties of the…
Diversity in hydrogen-rich envelope mass of type II supernovae (II): SN 2023ixf as explosion of partially-stripped intermediate massive star
Qiliang Fang, Takashi J. Moriya, Lucía Ferrari +6
SN 2023ixf is one of the most well-observed core-collapse supernova in recent decades, yet there is inconsistency in the inferred zero-age-main-sequence (ZAMS) mass …
Progenitor mass and ejecta asymmetry of SN 2023ixf from nebular spectroscopy
Lucía Ferrari, Gastón Folatelli, Keila Ertini +2
Context. SN 2023ixf was discovered in Galaxy M101 in May 2023. Its proximity made it an extremely valuable opportunity for the scientific community to study the characteristics of…
Final Moments II: Observational Properties and Physical Modeling of CSM-Interacting Type II Supernovae
W. V. Jacobson-Galán, L. Dessart, K. W. Davis +52
We present ultraviolet/optical/near-infrared observations and modeling of Type II supernovae (SNe II) whose early-time ( days) spectra show transient, narrow emission lines…
Circumstellar interaction models for the early bolometric light curve of SN 2023ixf
L. Martinez, M. C. Bersten, G. Folatelli +2
SNe II show growing evidence of interaction with CSM surrounding their progenitor stars as a consequence of enhanced mass loss during the last years of the progenitor's life. We pr…
