DDO 68: A flea with smaller fleas that on him prey
F. Annibali, C. Nipoti, L. Ciotti +7
We present new photometry of the dwarf irregular galaxy DDO 68, one of the most metal-poor and least massive dwarfs, located in the Lynx-Cancer Void. The images were acquired with…
Constraints on photoionization feedback from number counts of ultra-faint high-redshift galaxies in the Frontier Fields
M. Castellano, B. Yue, A. Ferrara +11
We exploit a sample of ultra-faint high-redshift galaxies (demagnified HST magnitude ) in the Frontier Fields clusters A2744 and M0416 to constrain a theoretical mod…
The ASTRODEEP Frontier Fields Catalogues: II - Photometric redshifts and rest-frame properties in Abell-2744 and MACS-J0416
M. Castellano, R. Amorín, E. Merlin +35
We present the first public release of photometric redshifts, galaxy rest-frame properties and associated magnification values in the cluster and parallel pointings of the first tw…
The ASTRODEEP Frontier Fields Catalogues: I - Multiwavelength photometry of Abell-2744 and MACS-J0416
E. Merlin, R. Amorìn, M. Castellano +28
We present multiwavelength photometric catalogues (HST, Spitzer and Hawk-I K band) for the first two of the Frontier Fields, Abell2744 and MACSJ0416 (plus their parallel fields). T…
First observational support for overlapping reionized bubbles generated by a galaxy overdensity
M. Castellano, P. Dayal, L. Pentericci +21
We present the analysis of deep HST multi-band imaging of the BDF field specifically designed to identify faint companions around two of the few Ly-alpha emitting galaxies spectros…
