Examining extinction distributions for type Ia supernovae in simulated 3D galaxies
João Duarte, Santiago González-Gaitán, Ana M. Mourão +2
Dust extinction and reddening greatly contribute to type Ia supernovae (SNe Ia) observed color and magnitude variations. The models used to describe the extinction probability dens…
On the impact of the supernova subsamples in reducing the Hubble tension
Gonçalo Martins, Santiago González-Gaitán, João Duarte +1
The persistent 4-6 difference between early- and late-time Hubble constant () measurements, known as the "Hubble tension", is a major problem in modern cosmology. We stu…
Narrow absorption lines from intervening material in supernovae. IV. Type Ia supernovae: Na I D line strength relating to external material and intrinsic properties
Santiago González-Gaitán, Claudia P. Gutiérrez, João Duarte +4
Type Ia supernovae (SNe Ia) are thermonuclear runaways of some white dwarfs in binary systems. They have been extensively studied, yet their progenitor and explosion mechanisms rem…
Light-Curve and Spectral Properties of Type II Supernovae from the ATLAS survey
K. Ertini, J. P. Anderson, G. Folatelli +22
Type II supernovae (SNe II) are the most common terminal stellar explosions in the Universe. With SNe now being detected within days after explosion, there is growing evidence that…
Narrow absorption lines from intervening material in supernovae: III. Supernovae and their environments
Claudia P. Gutiérrez, Santiago González-Gaitán, Joseph P. Anderson +1
Narrow interstellar absorption features in supernova (SN) spectra serve as valuable diagnostics for probing dust extinction and the presence of circumstellar or interstellar materi…
Exploring the origins of high-velocity features in SNe Ia with the spectral synthesis code TARDIS
Luke Harvey, Kate Maguire, Alexander Holas +8
Appearing as secondary higher-velocity absorption components, high-velocity features (HVFs) have been observed in several absorption lines in many Type Ia supernovae (SNe Ia). The…
