The progenitors and circumstellar environments of stripped-envelope interacting supernovae from BPASS
B. Warwick, J. Lyman, D. L. Coppejans +4
Understanding the progenitors of stripped-envelope interacting supernovae (SEISNe) is crucial for probing the final stages of massive star evolution. Despite this, their rarity mea…
Direct detections of white dwarfs in four WD+dM post-common envelope binaries within 20 pc
Mairi W. O'Brien, David J. Wilson, Pier-Emmanuel Tremblay +5
The paper reports the first direct spectroscopic detections of white dwarf companions in four nearby post‑common envelope binaries, using HST near‑UV observations to determine thei…
First Light And Reionization Epoch Simulations (FLARES) XXI: The UV Indices of Galaxies in the Early Universe
Connor Sant Fournier, Stephen M. Wilkins, Joseph Caruana +5
UV absorption line indices trace chemical enrichment and star formation histories in high-redshift galaxies, yet their reliability as quantitative stellar metallicity, Z*, diagnost…
Helium-burning blue large-amplitude pulsators: A Population Study with BPASS
Zhengyang Zhang, Conor M. Byrne, Chengyuan Wu +1
Blue Large-Amplitude Pulsators (BLAPs) are a class of radially pulsating stars with effective temperatures ranging from 20,000 to 35,000 K and pulsation periods between 7 and 75 mi…
Impact of Uncertainties in Spectral Energy Distribution Modelling on Inferred Galaxy Properties
Gareth T. Jones, Conor M. Byrne, Elizabeth R. Stanway
Interpreting galaxy properties from astronomical surveys relies heavily on spectral energy distribution (SED) modelling, yet uncertainties in key model ingredients are often overlo…
What do we mean by stellar mass? The impact of the pre-main sequence on the mass to light ratio of young and intermediate age stellar populations
Elizabeth R. Stanway, Conor M. Byrne, Ankur Upadhyaya
Stellar population synthesis models are an essential tool with which galaxy physical parameters are extracted from observations. However they are built on assumptions designed for…
