The host galaxies of 2003fg-like type Ia supernovae
Lluís Galbany, Chris Ashall, Jing Lu +19
SN~2003fg-like events are a peculiar type Ia supernova (SN~Ia) subtype characterized by broader light curves, higher near-infrared luminosities, and stronger carbon absorptions at…
The local ultraviolet signature of Type Ia supernova environments from HST and MUSE
Lluís Galbany, Cullen Abelson, Alaa Alburai +17
The local environment of a Type Ia supernova (SN~Ia) traces the local stellar-population age (a statistical proxy for the progenitor age), star formation, dust, and chemical enrich…
SN 2021aaev: a Hydrogen-Rich Superluminous Supernova with Early Flash and Long-Lived Circumstellar Interaction in an Unusual Host Environment
Yang Hu, Ragnhild Lunnan, Priscila J. Pessi +25
We present photometric and spectroscopic observations of SN\,2021aaev, a hydrogen-rich, superluminous supernova with persistent (at least days) narrow Balmer lines (SLSN-…
Unveiling the nature of SN 2022jli: The first double-peaked stripped-envelope supernova showing periodic undulations and dust emission at late times
Régis Cartier, Carlos Contreras, Maximilian Stritzinger +6
We present optical and infrared observations from maximum light until around +800 days of supernova (SN) 2022jli, a peculiar stripped-envelope (SE) SN showing two maxima, each one…
Discovery and Extensive Follow-Up of SN 2024ggi, a nearby type IIP supernova in NGC 3621
Ting-Wan Chen, Sheng Yang, Shubham Srivastav +45
We present the discovery and early observations of the nearby Type II supernova (SN) 2024ggi in NGC 3621 at 6.64 +/- 0.3 Mpc. The SN was caught 5.8 (+1.9 -2.9) hours after its expl…
The metamorphosis of the Type Ib SN 2019yvr: late-time interaction
Lucía Ferrari, Gastón Folatelli, Hanindyo Kuncarayakti +32
We present observational evidence of late-time interaction between the ejecta of the hydrogen-poor Type Ib supernova (SN) 2019yvr and hydrogen-rich circumstellar material (CSM), si…
Strong Carbon Features and a Red Early Color in the Underluminous Type Ia SN 2022xkq
Jeniveve Pearson, David J. Sand, Peter Lundqvist +85
We present optical, infrared, ultraviolet, and radio observations of SN 2022xkq, an underluminous fast-declining type Ia supernova (SN Ia) in NGC 1784 ( Mpc),…
The carbon-rich type Ic supernova 2016adj in the iconic dust lane of Centaurus A: signatures of interaction with circumstellar hydrogen?
Maximilian D. Stritzinger, Eddie Baron, Francesco Taddia +24
We present a comprehensive data set of supernova (SN) 2016adj located within the central dust lane of Centaurus A. SN 2016adj is significantly reddened and after correcting the pea…
Recovering lost light: discovery of supernova remnants with integral field spectroscopy
Héctor Martínez-Rodríguez, Lluís Galbany, Carles Badenes +8
We present results from a systematic search for broad ( 400 \kms) \ha\ emission in Integral Field Spectroscopy data cubes of 1200 nearby galaxies obtained with PMAS and…
Carnegie Supernova Project-II: Near-infrared Spectroscopic Diversity of Type II Supernovae
S. Davis, E. Y. Hsiao, C. Ashall +24
We present near-infrared (NIR) spectra of Type II supernovae (SNe II) from the Carnegie Supernova Project-II (CSP-II), the largest such dataset published to date. We iden…
Investigating the diversity of supernovae type Iax: A MUSE and NOT spectroscopic study of their environments
J. D. Lyman, F. Taddia, M. D. Stritzinger +9
SN 2002cx-like Type Ia supernovae (also known as SNe Iax) represent one of the most numerous peculiar SN classes. They differ from normal SNe Ia by having fainter peak magnitudes,…
On the multiplicity of supernovae within host galaxies
J. P. Anderson, M. Soto
We investigate the nature of multiple supernova hosting galaxies, and the types of events which they produce. Using all known historical supernovae, we split host galaxies into sam…
A Central Excess of Stripped-Envelope Supernovae within Disturbed Galaxies
S. M. Habergham, P. A. James, J. P. Anderson
This paper presents an analysis of core-collapse supernova distributions in isolated and interacting host galaxies, paying close attention to the selection effects involved in cond…
Progenitor mass constraints for core-collapse supernovae from correlations with host galaxy star formation
J. P. Anderson, S. M. Habergham, P. A. James +1
Using H-alpha emission as a tracer of on-going (<16 Myr old) and near-UV emission as a tracer of recent (16-100 Myr old) star formation (SF), we present constraints on core-collaps…
The Type II supernovae 2006V and 2006au: two SN 1987A-like events
F. Taddia, M. D. Stritzinger, J. Sollerman +11
Supernova 1987A revealed that a blue supergiant (BSG) star can end its life as a core-collapse supernova (SN). SN 1987A and other similar objects exhibit properties that distinguis…
On the multiple supernova population of Arp 299: constraints on progenitor properties and host galaxy star formation characteristics
J. P. Anderson, S. M. Habergham, P. A. James
Throughout the last 20 years 7 supernovae (SNe) have been discovered within Arp 299. One of these is unclassified, leaving 6 core-collapse events; 2 type II, 2 type Ib, a type IIb…
Observational constraints on the progenitor metallicities of core-collapse supernovae
