Cosmology with Type Ia supernovae
Since 1998 (Riess et al. 1, Perlmutter et al. 2), surveys of cosmologically distant Type Ia supernovae (SNe Ia) have indicated an acceleration of the expansion of the Universe, distant SNe Ia being dimmer that expected in a decelerating Universe. With the assumption that the Universe can be described on average as isotropic and homogeneous, this acceleration implies either the existence of a fl...
متن کاملCosmology with type-Ia supernovae
I review the use of type-Ia supernovae (SNe) for cosmological studies. After briefly recalling the main features of type-Ia SNe that lead to their use as cosmological probes, I briefly describe current and planned type-Ia SNe surveys, with special emphasis on their physics reach in the presence of systematic uncertainties, which will be dominant in nearly all cases.
متن کاملType Ia Supernovae and Cosmology
I discuss the use of Type Ia supernovae (SNe Ia) for cosmological distance determinations. Low-redshift SNe Ia (z < ∼ 0.1) demonstrate that the Hubble expansion is linear with H0 = 72 ± 8 km s −1 Mpc, and that the properties of dust in other galaxies are generally similar to those of dust in the Milky Way. The light curves of high-redshift (z = 0.3– 1) SNe Ia are stretched in a manner consisten...
متن کاملMeasuring cosmology with Supernovae
Over the past decade, supernovae have emerged as some of the most powerful tools for measuring extragalactic distances. A well developed physical understanding of type II supernovae allow them to be used to measure distances independent of the extragalactic distance scale. Type Ia supernovae are empirical tools whose precision and intrinsic brightness make them sensitive probes of the cosmologi...
متن کاملModels for Type Ia Supernovae and Cosmology
From the spectra and light curves it is clear that SNIa events are thermonuclear explosions of white dwarfs. However, details of the explosion are highly under debate. Here, we present detailed models which are consistent with respect to the explosion mechanism, the optical and infrared light curves (LC), and the spectral evolution. This leaves the description of the burning front and the struc...
