Spectral ageing analysis of a Giant Radio Quasar: PKS 1127-130

Sagar Sethi, Marek Jamrozy and Agnieszka Kuźmicz

Giant radio galaxies (GRGs) have been well known for decades (e.g., Willis et al., 1974). These spectacular objects have recently grown in a significant number thanks to the dedicated search using large-area sky surveys. Although the statistical study of the population of GRGs is currently advanced, careful examination of individual objects is still not very propagated and covers the small number of access. Therefore we decided to examine carefully one of the largest, the brightest, and distant GRG, PKS 1127-130. Using multiwavelength dedicated and archival observations, we determined the average synchrotron age of the lobe and several other important physical parameters of this object.
