A mass threshold in the number density of passive galaxies at z2
V. Sommariva, A. Fontana, A. Lamastra +16
The process that quenched star formation in galaxies at intermediate and high redshift is still the subject of considerable debate. One way to investigate this puzzling issue is to…
A 52 hours VLT/FORS2 spectrum of a bright z~7 HUDF galaxy: no Ly-alpha emission
E. Vanzella, A. Fontana, L. Pentericci +7
We aim to determine the redshift of GDS-1408, the most solid z~7 galaxy candidate lying in the Hubble Ultra Deep Field. We have used all the VLT spectra of GDS-1408 collected by us…
Ultra-faint high-redshift galaxies in the Frontier Fields
Bin Yue, Andrea Ferrara, Eros Vanzella +1
By combining cosmological simulations with Frontier Fields project lens models we find that, in the most optimistic case, galaxies as faint as (AB magnitude at…
Evidence of very low metallicity and high ionization state in a strongly lensed, star-forming dwarf galaxy at z=3.417
Ricardo Amorín, A. Grazian, M. Castellano +6
We investigate the gas-phase metallicity and Lyman Continuum (LyC) escape fraction of a strongly gravitationally lensed, extreme emission-line galaxy at z=3.417, J1000+0221S, recen…
New observations of z~7 galaxies: evidence for a patchy reionization
L. Pentericci, E. Vanzella, A. Fontana +18
We present new results from our search for z~7 galaxies from deep spectroscopic observations of candidate z-dropouts in the CANDELS fields. Despite the extremely low flux limits ac…
PdBI Cold Dust Imaging of Two Extremely Red H-[4.5]>4 Galaxies Discovered with SEDS and CANDELS
Karina I. Caputi, Michal J. Michalowski, Melanie Krips +11
We report Plateau de Bure Interferometer (PdBI) 1.1 mm continuum imaging towards two extremely red H-[4.5]>4 (AB) galaxies at z>3, which we have previously discovered making use of…
Characterizing faint galaxies in the reionization epoch: LBT confirms two L<0.2L* sources at z=6.4 behind the CLASH/Frontier Fields cluster MACS0717.5+3745
E. Vanzella, A. Fontana, A. Zitrin +18
We report the LBT/MODS1 spectroscopic confirmation of two images of faint Lyman alpha emitters at behind the Frontier Fields galaxy cluster MACSJ0717.5+3745. A wide range o…
