Forecasts on neutrino mass constraints from the redshift-space two-point correlation function
Fernanda Petracca, Federico Marulli, Lauro Moscardini +3
We provide constraints on the accuracy with which the neutrino mass fraction, , can be estimated when exploiting measurements of redshift-space distortions, describing in part…
The XXL survey XIV. AAOmega redshifts for the southern XXL field
C. Lidman, F. Ardila, M. Owers +15
We present a catalogue containing the redshifts of 3,660 X-ray selected targets in the XXL southern field. The redshifts were obtained with the AAOmega spectrograph and 2dF fibre p…
The XXL Survey: I. Scientific motivations - XMM-Newton observing plan - Follow-up observations and simulation programme
M. Pierre, F. Pacaud, C. Adami +89
We present the XXL Survey, the largest XMM programme totaling some 6.9 Ms to date and involving an international consortium of roughly 100 members. The XXL Survey covers two extrag…
KAT-7 observations of a mass-selected sample of galaxy clusters
G. Bernardi, T. Venturi, R. Cassano +7
The presence of megaparsec-scale radio halos in galaxy clusters has already been established by many observations over the last two decades. The emerging explanation for the format…
The Galaxy Cluster Concentration-Mass Scaling Relation
Austen M. Groener, David M. Goldberg, Mauro Sereno
Scaling relations of clusters have made them particularly important cosmological probes of structure formation. In this work, we present a comprehensive study of the relation betwe…
The Imprint of f(R) Gravity on Non-Linear Structure Formation
Ixandra Achitouv, Marco Baldi, Ewald Puchwein +1
We test the imprint of f(R) modified gravity on the halo mass function, using N-body simulations and a theoretical model developed in (Kopp et al. 2013). We find a very good agreem…
Resolving the Extragalactic -ray Background above 50 GeV with Fermi-LAT
LAT Collaboration
The Fermi Large Area Telescope (LAT) Collaboration has recently released a catalog of 360 sources detected above 50 GeV (2FHL). This catalog was obtained using 80 months of data re…
MultiDarkLens Simulations: weak lensing light-cones and data base presentation
Carlo Giocoli, Eric Jullo, R. Benton Metcalf +10
In this paper we present a large database of weak lensing light cones constructed using different snapshots from the Big MultiDark simulation (BigMDPL). The ray-tracing through dif…
Zoomed high-resolution simulations of Multi-coupled Dark Energy: cored galaxy density profiles at high redshift
E. Garaldi, M. Baldi, L. Moscardini
We perform for the first time high-resolution zoom-in re-simulations of individual halos in the context of the Multi-coupled Dark Energy (McDE) scenario, which is characterised by…
CosmoBolognaLib: C++ libraries for cosmological calculations
Federico Marulli, Alfonso Veropalumbo, Michele Moresco
We present the CosmoBolognaLib, a large set of Open Source C++ numerical libraries for cosmological calculations. CosmoBolognaLib is a living project aimed at defining a common num…
Measuring the distance-redshift relation with the baryon acoustic oscillations of galaxy clusters
Alfonso Veropalumbo, Federico Marulli, Lauro Moscardini +2
We analyse the largest spectroscopic samples of galaxy clusters to date, and provide observational constraints on the distance-redshift relation from baryon acoustic oscillations.…
The effect of interacting dark energy on local measurements of the Hubble constant
Io Odderskov, Marco Baldi, Luca Amendola
In the current state of cosmology, where cosmological parameters are being measured to percent accuracy, it is essential to understand all sources of error to high precision. In th…
The Low Redshift survey at Calar Alto (LoRCA)
J. Comparat, C. -H. Chuang, S. Rodriguez-Torres +13
The Baryon Acoustic Oscillation (BAO) feature in the power spectrum of galaxies provides a standard ruler to measure the accelerated expansion of the Universe. To extract all avail…
Do radio mini-halos and gas heating in cool-core clusters have a common origin?
Luca Bravi, Myriam Gitti, Gianfranco Brunetti
In this letter we present a study of the central regions of cool-core clusters hosting radio mini-halos, which are diffuse synchrotron sources extended on cluster-scales surroundin…
Prospects for clustering and lensing measurements with forthcoming intensity mapping and optical surveys
Alkistis Pourtsidou, David Bacon, Robert Crittenden +1
We explore the potential of using intensity mapping surveys (MeerKAT, SKA) and optical galaxy surveys (DES, LSST) to detect HI clustering and weak gravitational lensing of 21cm emi…
A conservative assessment of the current constraints on dark matter annihilation from Cosmic Rays and CMB observations
Nicolò Masi, Mario Ballardini
In view of the current interest in combining different observations to constraint annihilating WIMP dark matter, we examine the relation between the Sommerfeld effect at the recomb…
Missing baryons traced by the galaxy luminosity density in the large-scale WHIM filaments
J. Nevalainen, E. Tempel, L. J. Liivamägi +9
We propose a new approach to the missing baryons problem. Building on the common assumption that the missing baryons are in the form of the Warm Hot Intergalactic Medium (WHIM), we…
Fitting and forecasting non-linear coupled dark energy
Santiago Casas, Luca Amendola, Marco Baldi +2
We consider cosmological models in which dark matter feels a fifth force mediated by the dark energy scalar field, also known as coupled dark energy. Our interest resides in estima…
