Core-Collapse Supernova detections from Einstein Telescope within the Milky Way

I. F. Giudice, A. L. De Santis, M. T. Botticella +6

Core-collapse supernovae are key drivers of galaxy evolution and promising sources of gravitational waves, which provide a unique probe of the physics driving their explosion mecha…

Constraining inhomogeneities and asymmetries in SNe, FBOTs, and other high-energy transients from unresolved radio observations

Fabio De Colle, Rosa L. Becerra, Lizeth A. Meza +7

Synchrotron emission in high-energy transients is produced by relativistic electrons accelerated by shocks. As high-energy transients are often unresolved even on angular scales pr…

AT 2024ahzi: A Type IIP Supernova Discovered by the LSST Commissioning Camera

Kaylee de Soto, V. Ashley Villar, Jared A. Goldberg +25

As part of its commissioning, the Vera C. Rubin Observatory observed several fields repeatedly for a month with ComCam, an instrument that uses the same hardware as the LSST camera…

Normal or transitional? The evolution and properties of two type Ia supernovae in the Virgo cluster

L. Izzo, C. Gall, N. Khetan +47

Type Ia supernovae (SNe Ia) are among the most precise cosmological distance indicators used to study the expansion history of the Universe. The vast increase of SN Ia data due to…

Characterization of type Ibn SNe

D. Farias, C. Gall, V. A. Villar +29

Type Ibn supernovae (SNe) are characterized by narrow helium (He I) lines from photons produced by the unshocked circumstellar material (CSM). About 80 SNe Ibn have been discovered…

The New Status Qvo? SN 2021qvo is Another 2003fg-like Type Ia Supernova with a Rising Light-Curve Bump

I. A. Abreu Paniagua, W. B. Hoogendam, D. O. Jones +24

In recent years, multiple Type Ia supernovae (SNe Ia) have been observed with ''bumps'' in their rising light curves shortly after explosion. Here, we present SN 2021qvo: a SN Ia t…

SN 2021foa: The "Flip-Flop" Type IIn / Ibn supernova

D. Farias, C. Gall, G. Narayan +29

We present a comprehensive analysis of the photometric and spectroscopic evolution of SN~2021foa, unique among the class of transitional supernovae for repeatedly changing its spec…

Double "acct": a distinct double-peaked supernova matching pulsational pair-instability models

C. R. Angus, S. E. Woosley, R. J. Foley +35

We present multi-wavelength data of SN2020acct, a double-peaked stripped-envelope supernova (SN) in NGC2981 at ~150 Mpc. The two peaks are temporally distinct, with maxima separate…

Origin of the strong sodium absorption of the lensed supernova 2016geu at z=0.4

Christa Gall, Jens Hjorth, Lise Christensen +7

The origin of strong sodium absorption, which has been observed for a few nearby Type Ia supernovae (SNe Ia), remains elusive. Here we analyse two high-signal-to-noise, intermediat…

SN 2024ggi in NGC 3621: Rising Ionization in a Nearby, CSM-Interacting Type II Supernova

W. V. Jacobson-Galán, K. W. Davis, C. D. Kilpatrick +28

We present UV/optical/NIR observations and modeling of supernova (SN) 2024ggi, a type II supernova (SN II) located in NGC 3621 at 7.2 Mpc. Early-time ("flash") spectroscopy of SN 2…

SN 2022oqm: A Bright and Multi-peaked Calcium-rich Transient

S. Karthik Yadavalli, V. Ashley Villar, Luca Izzo +60

We present the photometric and spectroscopic evolution of SN 2022oqm, a nearby multi-peaked hydrogen- and helium-weak calcium-rich transient (CaRT). SN 2022oqm was detected 13.1 kp…
