Constraints on intergalactic dust from quasar colours
Edvard Mortsell, Ariel Goobar
Colour measurements of quasars are used to constrain the abundance and properties of intergalactic dust and the related extinction effects on high-z sources. For Type Ia supernovae…

Constraining photon-axion oscillations using quasar spectra
Edvard Mortsell, Ariel Goobar
Using quasar spectra from the SDSS survey, we constrain the possibility of photon-axion oscillations as a source of dimming of high redshift objects. Such a process has been sugges…
