Accretion models predict that fluorescence lines broadened by relativistic effects should arise from reflection of X-ray emission onto the inner region of the accretion disc surrounding the central black hole of active galactic nuclei (AGN). The theory behind the origin of relativistic lines is w...Tags: high energy astrophysical phenomena, xray, agn, xmm, radio, arxiv, a&a

Multiwavelength Observations of Radio-quiet Quasars with Weak Emission Lines
We present radio and X-ray observations, as well as optical light curves, for a subset of 26 BL Lac candidates from the Sloan Digital Sky Survey (SDSS) lacking strong radio emission and with z<2.2. Half of these 26 objects are shown to be stars, galaxies, or absorbed quasars. We conclude that ...Tags: arxivs, mnras, agn, xray, sdss

Modelling the radio pulses of an ultracool dwarf
Recently unanticipated magnetic activity in ultracool dwarfs (UCDs, spectral classes later than M7) have emerged from a number of radio observations. The highly (up to 100%) circularly polarized nature and high brightness temperature of the emission has been interpreted as an effective amplificat...Tags: arxiv, a&a, solar and stellar astrophysics, ucds, brown dwards, tvlm513, xray, radio
