Reflecting on the various dichotomies through which human rights have traditionally been understood, this book takes account of recent developments in both theories of rights and in international human rights law to present new ways of thinking about some long-standing problems. Leading legal and political philosophers, social theorists and scholars of international law discuss traditional dilemmas and taxonomies in human rights theory, engaging with contemporary scholarship and current practice. The book examines various tensions, such as those between legal and moral rights, positive and neg

Tidal disruption events (TDEs) are transient flares produced when a star is ripped apart by the gravitational field of a supermassive black hole (SMBH). We have observed a transient source in the western nucleus of the merging galaxy pair Arp 299 that radiated >1.5 × 10 erg at infrared and radio wavelengths but was not luminous at optical or x-ray wavelengths. We interpret this as a TDE with much of its emission reradiated at infrared wavelengths by dust. Efficient reprocessing by dense gas and dust may explain the difference between theoretical predictions and observed luminosities of TDEs. The radio observations resolve an expanding and decelerating jet, probing the jet formation and evolution around a SMBH.
