The contribution of faint AGNs to the ionizing background at z~4
A. Grazian, E. Giallongo, K. Boutsia +21
Finding the sources responsible for the hydrogen reionization is one of the most pressing issues in cosmology. Bright QSOs are known to ionize their surrounding neighborhood, but t…
Variable stars and stellar populations in Andromeda XXV: III. A central cluster or the galaxy nucleus?
Felice Cusano, Alessia Garofalo, Gisella Clementini +8
We present B and V time-series photometry of Andromeda XXV, the third galaxy in our program on the Andromeda's satellites, that we have imaged with the Large Binocular Cameras of t…
On the use of asymmetric PSF on NIR images of crowded stellar fields
Giuliana Fiorentino, Ivan Ferraro, Giacinto Iannicola +8
We present data collected using the camera PISCES coupled with the Firt Light Adaptive Optics (FLAO) mounted at the Large Binocular Telescope (LBT). The images were collected using…
The extended structure of the dwarf irregular galaxies Sextans A and Sextans B. Signatures of tidal distortion in the outskirts of the Local Group
M. Bellazzini, G. Beccari, F. Fraternali +7
We present a detailed study of the stellar and HI structure of the dwarf irregular galaxies SextansA and SextansB, members of the NGC3109 association. We use newly obtained deep (r…
