Spectral Diversity in Type Ibn Supernovae and the Large Host Offset of SN2024acyl
Yize Dong, V. Ashley Villar, Anya Nugent +35
In this paper, we first present observations of SN~2024acyl, a normal Type Ibn supernova with a large projected offset (35~kpc) from its host galaxy. The low star-formation r…
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…
A long-lasting eruption heralds SN 2023ldh, a clone of SN 2009ip
A. Pastorello, A. Reguitti, L. Tartaglia +46
We discuss the results of the spectroscopic and photometric monitoring of the type IIn supernova (SN) 2023ldh. Survey archive data show that the SN progenitor experienced some erra…
Evidence for an Instability-Induced Binary Merger in the Double-Peaked, Helium-Rich Type IIn Supernova 2023zkd
A. Gagliano, V. A. Villar, T. Matsumoto +42
We present ultraviolet to infrared observations of the extraordinary Type IIn supernova 2023zkd (SN 2023zkd). Photometrically, it exhibits persistent and luminous precursor emissio…
A Pristine-UNIONS view on the Galaxy: Kinematics of the distant spur feature of the Sagittarius stream traced by Blue Horizontal Branch stars
M. Bayer, E. Starkenburg, G. F. Thomas +14
Providing a detailed picture of the Sagittarius (Sgr) stream offers important constraints on the build-up of the Galactic halo as well as its gravitational potential at large radii…
Unions with UNIONS: Using galaxy-galaxy lensing to probe galaxy mergers
Isaac Cheng, Jack Elvin-Poole, Michael J. Hudson +12
We use galaxy-galaxy lensing to investigate how the dark matter (DM) haloes and stellar content of galaxies with and $10 \leq \log_{10}(M_\star/\mathrm{M}_…
