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…
Exploring the origins of high-velocity features in SNe Ia with the spectral synthesis code TARDIS
Luke Harvey, Kate Maguire, Alexander Holas +8
Appearing as secondary higher-velocity absorption components, high-velocity features (HVFs) have been observed in several absorption lines in many Type Ia supernovae (SNe Ia). The…
The ANDICAM-SOFI Near-infrared and Optical type Ia Supernova (ASNOS) sample: Description and data release
Kim Phan, Lluís Galbany, Tomás E. Müller-Bravo +13
Type Ia supernovae (SNe Ia) provide the most robust means of measuring extragalactic distances. While most of the effort has focused on increasing the number of SNe Ia observed in…
The Type Ia Supernova 2021hem: A 2003fg-like Event in an Apparently Hostless Environment
Subhash Bose, M. D. Stritzinger, A. Malmgaard +25
We report observations of Type Ia SN 2021hem, located in an apparently hostless environment. With a peak absolute B-band magnitude of -19.96 mag, and a lack of secondary maximum in…
SN 2023taz: Implications for the UV Diversity of Superluminous Supernovae
Aysha Aamer, Matt Nicholl, Charlotte Angus +21
Superluminous supernovae (SLSNe) are some of the brightest explosions in the Universe representing the extremes of stellar deaths. At the upper end of their distribution is SN\,202…
ZTF SNe Ia DR2: Towards cosmology-grade ZTF supernova light curves using scene modeling photometry
L. Lacroix, N. Regnault, T. de Jaeger +36
The Zwicky Transient Facility (ZTF) is conducting a wide-field survey of the northern sky in three optical bands and the collaboration cosmology working group has released 3628 spe…
ZTF SN Ia DR2 follow-up: Exploring the origin of the Type Ia supernova host galaxy step through Si II velocities
U. Burgaz, K. Maguire, L. Galbany +18
The relationship between Type Ia supernovae (SNe Ia) and their host galaxy stellar masses is well documented. In particular, Hubble residuals display a luminosity shift based on ho…
Long-term evolution of the SN 2009ip-like transient SN 2016cvk
K. Matilainen, E. Kankare, S. Mattila +21
The interacting transient SN 2016cvk (ASASSN-16jt) is a member of the peculiar SN 2009ip-like events. We present our follow-up data and aim to draw conclusions about the physical n…
A real-time search for Type Ia Supernovae with late-time CSM interaction in ZTF
Jacco H. Terwel, Kate Maguire, Seán J. Brennan +20
The nature of Type Ia supernova (SN Ia) progenitor systems and the mechanisms that lead up to their explosions are still widely debated. In rare cases the SN ejecta interact with c…
GRB 241105A: A test case for GRB classification and rapid r-process nucleosynthesis channels
Dimple, B. P. Gompertz, A. J. Levan +85
Gamma-ray bursts (GRBs) offer a powerful window to probe the progenitor systems responsible for the formation of heavy elements through the rapid neutron capture (r-) process, than…
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…
SN 2024abfo: a partially stripped SN II from a yellow supergiant
A. Reguitti, A. Pastorello, S. J. Smartt +35
We present photometric and spectroscopic data of the type IIb supernova (SN) 2024abfo in NGC 1493 (at 11 Mpc). The ATLAS survey discovered the object just a few hours after the exp…
Analyzing type Ia supernovae near-infrared light curves with Principal Component Analysis
T. E. Müller-Bravo, L. Galbany, M. D. Stritzinger +8
Type Ia supernovae (SNeIa), the thermonuclear explosions of C/O white dwarf stars in binary systems, are phenomena that remain poorly understood. The complexity of their progenitor…
ZTF SN Ia DR2: Improved SN Ia colors through expanded dimensionality with SALT3+
W. D. Kenworthy, A. Goobar, D. O. Jones +24
Type Ia supernovae (SNe Ia) are a key probe in modern cosmology, as they can be used to measure luminosity distances at gigaparsec scales. Models of their light-curves are used to…
