We review current understanding of the population of radio galaxies and radio-loud quasars
from an observational perspective, focusing on their large-scale structures and dynamics …

▪ Abstract At luminosities above 1011, infrared galaxies become the dominant population of
extragalactic objects in the local Universe (z≲ 0.3), being more numerous than optically …

We present an analytical description of the merging of virialized haloes which is applicable
to any hierarchical model in which structure grows via gravitational instability. The formulae …

Using numerical simulation, we study the development of gaseous inflows and triggering of
starburst activity in mergers of comparable-mass disk galaxies. In all encounters studied, the …

ABSTRACT I review the radio to X‐ray properties of gigahertz peaked‐spectrum (GPS) and
compact steep‐spectrum (CSS) sources, the current hypotheses for their origin, and their …

We observe spin blockade due to Pauli exclusion in the tunneling characteristics of a
coupled quantum dot system when two same-spin electrons occupy the lowest energy state …

Is every quasar beamed? ADS Classic is now deprecated. It will be completely retired in October
2019. This page will automatically redirect to the new ADS interface at that point. SAO/NASA …

We review accretion mechanisms for powering the central engines of active galactic nuclei
(AGN) and possible sources of fuel. Local sources, such as dense star clusters, require …

The recent development of unified theories of active galactic nuclei (AGN) has indicated that
there are two physically distinct classes of these objects-radio-loud and radio-quiet. The …

The triggering mechanism for the most luminous, quasar-like active galactic nuclei (AGN)
remains a source of debate, with some studies favouring triggering via galaxy mergers, but …
