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 stud…
from multi-waveband galaxy polarimetry in supernovae vicinity
João Rino-Silvestre, Santiago González-Gaitán, Ana Mourão +2
Peculiar dust extinction laws have been reported for some type Ia supernovae (SNe) with the parameter much lower than the average value for the Milky Way (MW) of 3.1. Using o…
Narrow absorption lines from intervening material in supernovae I. Measurements and temporal evolution
Santiago González-Gaitán, Claudia P. Gutiérrez, Joseph P. Anderson +6
Narrow absorption features in nearby supernova (SN) spectra are a powerful diagnostic of the slow-moving material in the line of sight: they are extensively used to infer dust exti…
Systematic errors on optical-SED stellar mass estimates for galaxies across cosmic time and their impact on cosmology
A. Paulino-Afonso, S. González-Gaitán, L. Galbany +7
Studying galaxies at different cosmic epochs entails several observational effects that need to be taken into account to compare populations across a large time span in a consisten…
CALIFA, the Calar Alto Legacy Integral Field Area survey: I. Survey presentation
S. F. Sanchez, R. C. Kennicutt, A. Gil de Paz +69
We present here the Calar Alto Legacy Integral Field Area (CALIFA) survey, which has been designed to provide a first step in this direction.We summarize the survey goals and desig…
