Photon underproduction crisis: Are QSOs sufficient to resolve it?

Are red 2MASS QSOs young?

We use photometric data from the Spitzer mission to explore the midand far-infrared properties of 10 red QSOs (J −K > 2, R −K > 5 mag) selected by combining the 2MASS in the near-infrared with the SDSS at optical wavelengths. Optical and/or near-infrared spectra are available for 8/10 sources. Modeling the Spectral Energy Distribution (SED) from UV to far-infrared shows that moderate dust redde...

What Does It Mean for a URI to Resolve?

Amongst the best practices that constitute Linked Data, one of the foremost is to use only HTTP-URIs as identifiers for RDF resources. This is so that the URI will resolve in a Linked Data browser to give information about the named resource. At the same time, Linked Data takes a resource-centric, as opposed to page-centric, approach to resolution. We argue that this approach can, in certain ca...
