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…
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…
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…
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…
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…
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…
