\textit{Euclid} preparation. Baryon acoustic oscillations extraction techniques: comparison and optimisation

Euclid Collaboration, E. Sarpa, A. Veropalumbo +296

We present the first end-to-end validation of the Euclid baryon acoustic oscillation (BAO) analysis pipeline, encompassing density-field reconstruction, two-point correlation funct…

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…

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…

Seeing the Outer Edge of the Infant Type Ia Supernova 2024epr in the Optical and Near Infrared

W. B. Hoogendam, D. O. Jones, C. Ashall +30

We present optical-to-near-infrared (NIR) photometry and spectroscopy of the Type Ia supernova (SN Ia) 2024epr, including NIR spectra observed within two days of first light. The e…

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…

Identification of the optical counterpart of the fast X-ray transient EP240414a

S. Srivastav, T. -W. Chen, J. H. Gillanders +26

Fast X-ray transients (FXTs) are extragalactic bursts of X-rays first identified in archival X-ray data, and now routinely discovered by the Einstein Probe in real time, which is c…

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…

SN 2023ixf in Messier 101: Photo-ionization of Dense, Close-in Circumstellar Material in a Nearby Type II Supernova

W. V. Jacobson-Galan, L. Dessart, R. Margutti +65

We present UV/optical observations and models of supernova (SN) 2023ixf, a type II SN located in Messier 101 at 6.9 Mpc. Early-time ("flash") spectroscopy of SN 2023ixf, obtained p…

A fast rising tidal disruption event from a candidate intermediate mass black hole

C. R. Angus, V. F. Baldassare, B. Mockler +36

Massive black holes (BHs) at the centres of massive galaxies are ubiquitous. The population of BHs within dwarf galaxies, on the other hand, is evasive. Dwarf galaxies are thought…

Neutrino constraints to scotogenic dark matter interacting in the Sun

Thede de Boer, Raffaela Busse, Alexander Kappes +2

Radiative seesaw models have the attractive property of providing dark matter candidates in addition to generation of neutrino masses. Here we present a study of neutrino signals f…

Dark matter implications of the KATRIN neutrino mass experiment

Thede de Boer, Michael Klasen, Caroline Rodenbeck +1

We studied the effects of the absolute neutrino mass scale in the scotogenic radiative seesaw model. From a scan over the parameter space of this model, a linear relation between t…
