Reeling in the Whirlpool: the distance to M 51 clarified by Cepheids and the Type IIP SN 2005cs
G. Csörnyei, R. I. Anderson, C. Vogl +4
Despite being one of the best-known galaxies, the distance to the Whirlpool Galaxy, M 51, is still debated. Current estimates range from 6.02 to 9.09 Mpc, and different methods yie…
Early-Time Ultraviolet and Optical Hubble Space Telescope Spectroscopy of the Type II Supernova 2022wsp
Sergiy S. Vasylyev, Christian Vogl, Yi Yang +9
We report early-time ultraviolet (UV) and optical spectroscopy of the young, nearby Type II supernova (SN) 2022wsp obtained by the Hubble Space Telescope (HST)/STIS at about 10 and…
Family dispute: do Type IIP supernova siblings agree on their distance?
Géza Csörnyei, Christian Vogl, Stefan Taubenberger +7
Context: Type II supernovae provide a direct way to estimate distances through the expanding photosphere method, which is independent of the cosmic distance ladder. A recently intr…
Observations of the Very Young Type Ia Supernova 2019np with Early-excess Emission
Hanna Sai, Xiaofeng Wang, Nancy Elias-Rosa +30
Early-time radiative signals from type Ia supernovae (SNe Ia) can provide important constraints on the explosion mechanism and the progenitor system. We present observations and an…
Early-Time Ultraviolet Spectroscopy and Optical Follow-up Observations of the Type IIP Supernova 2021yja
Sergiy S. Vasylyev, Alexei V. Filippenko, Christian Vogl +19
We present three epochs of early-time ultraviolet (UV) and optical HST/STIS spectroscopy of the young, nearby Type IIP supernova (SN) 2021yja. We complement the HST data with two e…
Scintillation and optical properties of xenon-doped liquid argon
C. Vogl, M. Schwarz, X. Stribl +3
Liquid argon (LAr) is a common choice as detection medium in particle physics and rare-event searches. Challenges of LAr scintillation light detection include its short emission wa…
