Galactic Winds in Cosmological Simulations of the Circumgalactic Medium
Paramita Barai, Matteo Viel, Stefano Borgani +7
(Abridged) We explore new observationally-constrained sub-resolution models of galactic outflows and investigate their impact on the circumgalactic medium (CGM) over redshifts z =…
The Ninth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the SDSS-III Baryon Oscillation Spectroscopic Survey
III Collaboration, Christopher P. Ahn, Rachael Alexandroff +224
The Sloan Digital Sky Survey III (SDSS-III) presents the first spectroscopic data from the Baryon Oscillation Spectroscopic Survey (BOSS). This ninth data release (DR9) of the SDSS…
On the relative Contribution of high-redshift Galaxies and Active Galactic Nuclei to Reionization
Fabio Fontanot, Stefano Cristiani, Eros Vanzella
In this paper we discuss the contribution of different astrophysical sources to the ionization of neutral hydrogen at different redshifts. We critically revise the arguments in fav…
The Lyman alpha forest flux probability distribution at z>3
F. Calura, E. Tescari, V. D'Odorico +4
We present a measurement of the Lyman alpha flux probability distribution function (PDF) measured from a set of eight high resolution quasar spectra with emission redshifts at 3.3…
On The Detection Of Ionizing Radiation Arising From Star-Forming Galaxies At Redshift z ~ 3-4 : Looking For Analogs Of "Stellar Reionizers"
Eros Vanzella, Yicheng Guo, Mauro Giavalisco +15
We use the spatially-resolved, multi-band photometry in the GOODS South field acquired by the CANDELS project to constrain the nature of candidate Lyman continuum (LyC) emitters at…
On the Evolution of the Star Formation Rate Function of Massive Galaxies. Constraints at 0.4<z<1.8 from the GOODS-MUSIC Catalogue
Fabio Fontanot, Stefano Cristiani, Paola Santini +3
[abridged] We study the evolution of the Star Formation Rate Function (SFRF) of massive galaxies over the 0.4<z<1.8 redshift range and its implications for our understanding of the…
