A simple yet effective model of galaxy mergers
Cesare Chiosi, Mauro D'Onofrio, Emanuela Chiosi
In the context of the hierarchical formation of galaxies, we investigated the role played by mergers in shaping the scale relations of galaxies, that is the projections of their Fu…
Chemical abundances along the quasar main sequence
A. Floris, P. Marziani, S. Panda +5
The 4D eigenvector 1 (E1) sequence has emerged as a powerful tool for organizing the observational and physical characteristics of type-1 active galactic nuclei (AGNs). In this stu…
From sub-solar to super-solar chemical abundances along the quasar main sequence
Paola Marziani, Alberto Floris, Alice Deconto-Machado +8
The 4D Eigenvector 1 sequence has proven to be a highly effective tool for organizing observational and physical properties of type 1 active galactic nuclei (AGN). In this paper, w…
An almost dark galaxy with the mass of the Small Magellanic Cloud
Mireia Montes, Ignacio Trujillo, Ananthan Karunakaran +9
Almost Dark Galaxies are objects that have eluded detection by traditional surveys such as the Sloan Digital Sky Survey (SDSS). The low surface brightness of these galaxies ((…
Quasar emission lines as virial luminosity estimators
P. Marziani, E. Bon, N. Bon +6
Quasars accreting matter at very high rates (known as extreme Population A [xA]) may provide a new class of distance indicators covering cosmic epochs from present day up to less t…
GASP. XV. A MUSE View of Extreme Ram-Pressure Stripping along the Line of Sight: Physical properties of the Jellyfish Galaxy JO201
C. Bellhouse, Y. L. Jaffe, S. L. McGee +14
We present a study of the physical properties of JO201, a unique disk galaxy with extended tails undergoing extreme ram-pressure stripping as it moves through the massive cluster A…
Extreme quasars at high redshift
M. L. Martınez-Aldama, A. Del Olmo, P. Marziani +5
Context:Quasars radiating at extreme Eddington ratios (xA) are likely a prime mover of galactic evolution and have been hailed as potential distance indicators. Their properties ar…
GASP. X: APEX detection of molecular gas in the tails and in the disks of ram-pressure stripped galaxies
A. Moretti, R. Paladino, B. M. Poggianti +8
Jellyfish galaxies in clusters are key tools to understand environmental processes at work in dense environments. The advent of Integral Field Spectroscopy has recently allowed to…
What does Civλ1549 tell us about the physical driver of the Eigenvector Quasar Sequence?
J. W. Sulentic, A. del Olmo, P. Marziani +8
Broad emission lines in quasars enable us to "resolve" structure and kinematics of the broad line emitting region (BLR) thought to in- volve an accretion disk feeding a supermassiv…
GASP II. A MUSE view of extreme ram-pressure stripping along the line of sight: kinematics of the jellyfish galaxy JO201
C. Bellhouse, Y. L. Jaffe, G. K. T. Hau +11
This paper presents a spatially-resolved kinematic study of the jellyfish galaxy JO201, one of the most spectacular cases of ram-pressure stripping (RPS) in the GASP (GAs Stripping…
OmegaWINGS: spectroscopy in the outskirts of local clusters of galaxies
A. Moretti, M. Gullieuszik, B. Poggianti +9
Studies of the properties of low-redshift cluster galaxies suffer, in general, from small spatial coverage of the cluster area. WINGS, the most homogeneous and complete study of ga…
Emission Line Galaxies and Active Galactic Nuclei in WINGS clusters
P. Marziani, M. D'Onofrio, D. Bettoni +7
We present the analysis of the emission line galaxies members of 46 low redshift (0.04 < z < 0.07) clusters observed by WINGS (WIde-field Nearby Galaxy cluster Survey, Fasano et al…
Galaxy Luminosity Functions in WINGS clusters
A. Moretti, D. Bettoni, B. M. Poggianti +9
Using V band photometry of the WINGS survey, we derive galaxy luminosity functions (LF) in nearby clusters. This sample is complete down to Mv=-15.15, and it is homogeneous, thus a…
Jellyfish galaxy candidates at low redshift
B. M. Poggianti, G. Fasano, A. Omizzolo +9
Galaxies that are being stripped of their gas can sometimes be recognized from their optical appearance. Extreme examples of stripped galaxies are the so-called ``jellyfish galaxie…
OmegaWINGS: OmegaCAM@VST observations of WINGS galaxy clusters
M. Gullieuszik, B. Poggianti, G. Fasano +13
The Wide-field Nearby Galaxy-cluster Survey (WINGS) is a wide-field multi-wavelength survey of X-ray selected clusters at z =0.04-0.07. The original 34'x34' WINGS field-of- view ha…
Morphological Fractions of Galaxies in WINGS Clusters: revisiting the Morphology-Density Paradigm
G. Fasano, B. M. Poggianti, D. Bettoni +11
We present the Morphology-Density and Morphology-Radius relations (T-Sigma and T-R, respectively) obtained from the WINGS database of galaxies in nearby clusters. Aiming to achieve…
Fifty Years of Quasars: Physical Insights and Potential for Cosmology
J. W. Sulentic, P. Marziani, D. Dultzin +2
Last year (2013) was more or less the 50th anniversary of the discovery of quasars. It is an interesting time to review what we know (and don't know) about them both empirically an…

A. Moretti, B. M. Poggianti, G. Fasano +15
[Abridged] To effectively investigate galaxy formation and evolution, it is of paramount importance to exploit homogeneous data for large samples of galaxies in different environme…
WINGS-SPE III: Equivalent width measurements, spectral properties and evolution of local cluster galaxies
J. Fritz, B. M. Poggianti, A. Cava +11
[Abridged] We investigate the frequency of the various spectral types as a function both of the clusters' properties and of the galaxies' characteristics. In this way, using the sa…
