EW[OIII] as an Orientation Indicator for Quasars: Implications for the Torus (2017)
Journal Article
Bisogni, S., Marconi, A., Risaliti, G., & Lusso, E. (2017). EW[OIII] as an Orientation Indicator for Quasars: Implications for the Torus. Frontiers in Astronomy and Space Sciences, 4, Article 48. https://doi.org/10.3389/fspas.2017.00048

We present an analysis of the average spectral properties of 12,000 SDSS quasars as a function of accretion disc inclination, as measured from the equivalent width of the [OIII] 5007Å line. The use of this indicator on a large sample of quasars from... Read More about EW[OIII] as an Orientation Indicator for Quasars: Implications for the Torus.

Quasars as standard candles (2017)
Journal Article
Lusso, E., & Risaliti, G. (2017). Quasars as standard candles. Astronomy & Astrophysics, 602, Article A79. https://doi.org/10.1051/0004-6361/201630079

Context. A tight non-linear relation exists between the X-ray and UV emission in quasars (i.e. LX ∝LUVγ), with a dispersion of ~0.2 dex over approximately three orders of magnitude in luminosity. Such observational evidence has two relevant consequen... Read More about Quasars as standard candles.

Type 2 AGN Host Galaxies in the Chandra-COSMOS Legacy Survey: No Evidence of AGN-driven Quenching (2017)
Journal Article
Suh, H., Civano, F., Hasinger, G., Lusso, E., Lanzuisi, G., Marchesi, S., …Vignali, C. (2017). Type 2 AGN Host Galaxies in the Chandra-COSMOS Legacy Survey: No Evidence of AGN-driven Quenching. Astrophysical Journal, 841(2), Article 102. https://doi.org/10.3847/1538-4357/aa725c

We investigate the star formation properties of a large sample of ~2300 X-ray-selected Type 2 Active Galactic Nuclei (AGNs) host galaxies out to $z\sim 3$ in the Chandra COSMOS Legacy Survey in order to understand the connection between the star form...
