Reionization of the Intergalactic Medium
Andrea Ferrara, Stefania Pandolfi
After recombination the cosmic gas was left in a cold and neutral state. However, as the first stars and black holes formed within early galactic systems, their UV and X-ray radiat…
Constraining Warm Dark Matter with high- supernova lensing
Stefania Pandolfi, Carmelo Evoli, Andrea Ferrara +1
We propose a new method to constrain the warm dark matter (WDM) particle mass, , based on the counts of multiply imaged, distant supernovae (SN) produced by strong lensing by…
Reionization and CMB non-Gaussianity
D. Munshi, P. S. Corasaniti, P. Coles +2
We show how cross-correlating a high redshift external tracer field, such as the 21cm neutral hydrogen distribution and product maps involving Cosmic Microwave Background (CMB) tem…
Dark Energy coupling with electromagnetism as seen from future low-medium redshift probes
E. Calabrese, M. Martinelli, S. Pandolfi +4
Beyond the standard cosmological model the late-time accelerated expansion of the universe can be reproduced by the introduction of an additional dynamical scalar field. In this ca…
A new method to measure the mass of galaxy clusters
Martina Falco, Steen H. Hansen, Radoslaw Wojtak +3
The mass measurement of galaxy clusters is an important tool for the determination of cosmological parameters describing the matter and energy content of the Universe. However, the…
Probing dark energy with redshift-drift
Matteo Martinelli, Stefania Pandolfi, C. J. A. P. Martins +1
Future redshift-drift measurements (also known as Sandage-Loeb signal) will be crucial to probe the so called "redshift desert", thus providing a new tool for cosmological studies.…
Featuring the primordial power spectrum: new constraints on interrupted slow-roll from CMB and LRG data
Micol Benetti, Stefania Pandolfi, Massimiliano Lattanzi +2
Using the most recent data from the WMAP, ACT and SPT experiments, we update the constraints on models with oscillatory features in the primordial power spectrum of scalar perturba…
Cosmic microwave background constraints on light dark matter candidates
Carmelo Evoli, Stefania Pandolfi, Andrea Ferrara
Unveiling the nature of cosmic dark matter (DM) is an urgent issue in cosmology. Here we make use of a strategy based on the search for the imprints left on the cosmic microwave ba…
Data-constrained reionization and its effects on cosmological parameters
Stefania Pandolfi, Andrea Ferrara, T. Roy Choudhury +2
We perform an analysis of the recent WMAP7 data considering physically motivated and viable reionization scenarios with the aim of assessing their effects on cosmological parameter…
Constraints on massive sterile neutrino species from current and future cosmological data
Elena Giusarma, Martina Corsi, Maria Archidiacono +4
Sterile massive neutrinos are a natural extension of the Standard Model of elementary particles. The energy density of the extra sterile massive states affects cosmological measure…
CMB Neutrino Mass Bounds and Reionization
Maria Archidiacono, Asantha Cooray, Alessandro Melchiorri +1
Current cosmic microwave background (CMB) bounds on the sum of the neutrino masses assume a sudden reionization scenario described by a single parameter that determines the onset o…
Impact of general reionization scenarios on extraction of inflationary parameters
Stefania Pandolfi, Elena Giusarma, Edward W. Kolb +6
Determination of whether the Harrison--Zel'dovich spectrum for primordial scalar perturbations is consistent with observations is sensitive to assumptions about the reionization sc…
The Herschel-SPIRE Legacy Survey (HSLS): the scientific goals of a shallow and wide submillimeter imaging survey with SPIRE
Asantha Cooray, Steve Eales, Scott Chapman +247
A large sub-mm survey with Herschel will enable many exciting science opportunities, especially in an era of wide-field optical and radio surveys and high resolution cosmic microwa…
Harrison-Z'eldovich primordial spectrum is consistent with observations
S. Pandolfi, A. Cooray, E. Giusarma +4
Inflation predicts primordial scalar perturbations with a nearly scale-invariant spectrum and a spectral index approximately unity (the Harrison--Zel'dovich (HZ) spectrum). The fir…
No Evidence for Dark Energy Dynamics from a Global Analysis of Cosmological Data
Paolo Serra, Asantha Cooray, Daniel E. Holz +3
We use a variant of principal component analysis to investigate the possible temporal evolution of the dark energy equation of state, w(z). We constrain w(z) in multiple redshift b…
When Did Cosmic Acceleration Start ?
Alessandro Melchiorri, Luca Pagano, Stefania Pandolfi
A precise determination, and comparison, of the epoch of the onset of cosmic acceleration, at redshift z_acc, and of dark energy domination, at z_eq, provides an interesting measur…
