The Radio Spectra of High Luminosity Compact Symmetric Objects (CSO-2s): Implications for Studies of Compact Jetted Active Galactic Nuclei
P. V. de la Parra, A. C. S Readhead, T. Herbig +18
This paper addresses, for the first time, a key aspect of the phenomenology of Compact Symmetric Objects (CSOs) -- the characteristics of their radio spectra. We present a radio-sp…
Predicting the Scaling Relations between the Dark Matter Halo Mass and Observables from Generalised Profiles I: Kinematic Tracers
Andrew Sullivan, Chris Power, Connor Bottrell
We investigate the relationship between a dark matter halo's mass profile and measures of the velocity dispersion of kinematic tracers within its gravitational potential. By predic…
Small-scale radio jets and tidal disruption events: A theory of high-luminosity compact symmetric objects
Andrew G. Sullivan, Roger D. Blandford, Mitchell C. Begelman +2
Double lobe radio sources associated with active galactic nuclei represent one of the longest studied groups in radio astronomy. A particular sub-group of double radio sources comp…
Polarization of Intrabinary Shock Emission in Spider Pulsars
Andrew G. Sullivan, Roger W. Romani
In `spider' pulsars, the X-ray band is dominated by Intrabinary Shock (IBS) synchrotron emission. While the double-peaked X-ray light curves from these shocks have been well charac…
Gamma-ray burst precursors from tidally resonant neutron star oceans: potential implications for GRB 211211A
Andrew G. Sullivan, Lucas M. B. Alves, Zsuzsa Márka +2
Precursor emission has been observed seconds to minutes before some short gamma-ray bursts. While the origins of these precursors remain unknown, one potential explanation relies o…
