An analysis of the Type Ia SN 2024gy and a comparison of different host extinction estimation techniques
Jacco H. Terwel, Kate Maguire, Cillian O'Donnell +38
Type Ia supernovae (SNe Ia) are well-known standardisable candles, and are one of the main ways to measure the distance to their host galaxies. However, extinction due to interstel…

Spectropolarimetry of NGC 1275 reveals a narrow-line radio galaxy with polarization parallel to its radio jet axis
F. Marin, T. Pursimo, I. Liodakis +4
Concomitant with the Imaging X-ray Polarimetry Explorer (IXPE) observation of the Perseus cluster, we obtained optical spectropolarimetry of its central active galactic nucleus, NG…

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…
