The failure of testing for cosmic opacity via the distance-duality relation
Vaclav Vavrycuk, Pavel Kroupa
The distance-duality relation (DDR) between the luminosity distance and the angular diameter distance is viewed as a powerful tool for testing for the opacity of the Un…
Universe opacity and Type Ia supernova dimming
Vaclav Vavrycuk
In this paper, I revoke a debate about an origin of Type Ia supernova (SN Ia) dimming. I argue that except for a commonly accepted accelerating expansion of the Universe, a conceiv…
Universe opacity and cosmic dynamics
Vaclav Vavrycuk
Equations of cosmic dynamics for a model of the opaque Universe are derived and tested on supernovae (SNe) Ia observations. The model predicts a cyclic expansion/contraction evolut…
Missing dust signature in the cosmic microwave background
Vaclav Vavrycuk
I examine a possible spectral distortion of the Cosmic Microwave Background (CMB) due to its absorption by galactic and intergalactic dust. I show that even subtle intergalactic op…
Impact of galactic and intergalactic dust on the stellar EBL
Vaclav Vavrycuk
Current theories assume that the low intensity of the stellar extragalactic background light (stellar EBL) is caused primarily by finite age of the Universe because the finite age…
