A new type of photoionized code required for the new era of X-ray spectroscopy [PDF]

open access: yes, 2004
With the advent of the present and future spatial X-ray missions, it becomes crucial to model correctly the line spectrum of X-ray emitting media. We have built a photoionization code, Titan, solving the transfer of a thousand lines and of the continuum ...

On the 10-micron silicate feature in Active Galactic Nuclei [PDF]

open access: yes, 2009
The 10-micron silicate feature observed with Spitzer in active galactic nuclei (AGN) reveals some puzzling behavior. It (1) has been detected in emission in type 2 sources, (2) shows broad, flat-topped emission peaks shifted toward long wavelengths in ...

Ranking lawyers using a social network induced by legal cases

open access: yesJournal of the Brazilian Computer Society, 2017
Who are the most effective lawyers in the Labor Court of Rio de Janeiro? Using data from tens of thousands of legal cases, we construct a network of lawyers (directed and weighted) in order to answer this and other questions.

Evidence of two-dimensional macroscopic quantum tunneling of a current-biased DC-SQUID [PDF]

open access: yes, 2003
The escape probability out of the superconducting state of a hysteretic DC-SQUID has been measured at different values of the applied magnetic flux. At low temperature, the escape current and the width of the probability distribution are temperature ...

Dust formation, evolution, and obscuration effects in the very high-redshift universe [PDF]

open access: yes, 2014
The evolution of dust at redshifts z>9, and consequently the dust properties, differs greatly from that in the local universe. In contrast to the local universe, core collapse supernovae (CCSNe) are the only source of thermally-condensed dust. Because of
