The non-linear X-ray/UV relation in active galactic nuclei: contribution of instrumental effects on the X-ray variability
Elisabeta Lusso
We have recently demonstrated that the non-linear relation between ultraviolet and X-ray luminosity in quasars is very tight (with an intrinsic dispersion of ~0.2 dex), once contam…
Cosmological constraints from the Hubble diagram of quasars at high redshifts
Guido Risaliti, Elisabeta Lusso
The concordance (LambdaCDM) model reproduces the main current cosmological observations assuming the validity of general relativity at all scales and epochs, the presence of cold d…
Towards an informed quest for accretion disc winds in quasars: the intriguing case of Ton 28
Emanuele Nardini, Elisabeta Lusso, Susanna Bisogni
We report on the detection of a blueshifted Fe K absorption feature in two consecutive XMM-Newton observations of the luminous blue quasar Ton 28, at the 4 cumulative significan…
QSO MUSEUM I: A sample of 61 extended Ly-emission nebulae surrounding quasars
F. Arrigoni Battaia, J. F. Hennawi, J. X. Prochaska +4
Motivated by the recent discovery of rare Enormous Lyman-Alpha Nebulae (ELAN) around z~2 quasars, we have initiated a long-term observational campaign with the MUSE instrument to d…
The molecular gas content in obscured AGN at z > 1
M. Perna, M. T. Sargent, M. Brusa +11
The standard AGN-galaxy co-evolutionary scenario predicts a phase of deeply buried supermassive black hole growth coexisting with a starburst (SB) before feedback phenomena deplete…
The spectral and environment properties of quasar pairs
Elisabeta Lusso, Michele Fumagalli, Marc Rafelski +5
We present the first results from our survey of intervening and proximate Lyman limit systems (LLSs) at 2.0-2.5 using the Wide Field Camera 3 on-board the Hubble Space Tel…
X-Ray Properties of AGN in Brightest Cluster Galaxies. I.A Systematic Study of the Chandra Archive in the and Redshift Range
Lilan Yang, Paolo Tozzi, Heng Yu +5
We present a search for nuclear X-ray emission in the brightest cluster galaxies (BCGs) of a sample of groups and clusters of galaxies extracted from the Chandra archive. The exqui…
Molecular outflow and feedback in the obscured Quasar XID2028 revealed by ALMA
M. Brusa, G. Cresci, E. Daddi +29
We imaged with ALMA and ARGOS/LUCI the molecular gas and the dust and stellar continuum in XID2028, an obscured QSO at z=1.593, where the presence of a massive outflow in the ioniz…
Astronomical Distance Determination in the Space Age. Secondary distance indicators
Bozena Czerny, Rachael Beaton, Michal Bejger +11
The formal division of the distance indicators into primary and secondary leads to difficulties in description of methods which can actually be used in two ways: with, and without…
