Chemical abundances and radial velocities in the extremely metal-poor galaxy DDO 68
F. Annibali, V. La Torre, M. Tosi +9
We present chemical abundances and radial velocities of six HII regions in the extremely metal-poor star-forming dwarf galaxy DDO 68. They are derived from deep spectra in the wave…
NuSTAR reveals that the heavily obscured nucleus of NGC 2785 was the contaminant of IRAS 09104+4109 in the BeppoSAX/PDS hard X-rays
C. Vignali, P. Severgnini, E. Piconcelli +7
The search for heavily obscured active galactic nuclei (AGNs) has been revitalized in the last five years by NuSTAR, which has provided a good census and spectral characterization…
Massive Star cluster formation under the microscope at z=6
E. Vanzella, F. Calura, M. Meneghetti +12
We report on a superdense star-forming region with an effective radius (R_e) smaller than 13 pc identified at z=6.143 and showing a star-formation rate density Σ_SFR~1000 Msun/yr/k…
The VANDELS ESO public spectroscopic survey: observations and first data release
L. Pentericci, R. J. McLure B. Garilli, O. Cucciati +93
This paper describes the observations and the first data release (DR1) of the ESO public spectroscopic survey "VANDELS, a deep VIMOS survey of the CANDELS CDFS and UDS fields". VAN…
The VANDELS ESO public spectroscopic survey
R. J. McLure, L. Pentericci, A. Cimatti +92
VANDELS is a uniquely-deep spectroscopic survey of high-redshift galaxies with the VIMOS spectrograph on ESO's Very Large Telescope (VLT). The survey has obtained ultra-deep optica…
The SINS/zC-SINF survey of z~2 galaxy kinematics: SINFONI adaptive optics-assisted data and kiloparsec-scale emission line properties
N. M. Förster Schreiber, A. Renzini, C. Mancini +29
We present the "SINS/zC-SINF AO survey" of 35 star-forming galaxies, the largest sample with deep adaptive optics-assisted (AO) near-infrared integral field spectroscopy at z~2. Th…
ALMA view of a massive spheroid progenitor: a compact rotating core of molecular gas in an AGN host at z=2.226
M. Talia, F. Pozzi, L. Vallini +16
We present ALMA observations at 107.291 GHz (band 3) and 214.532 GHz (band 6) of GMASS 0953, a star-forming galaxy at z=2.226 hosting an obscured AGN that has been proposed as a pr…
The 500 ks Chandra observation of the z = 6.31 QSO SDSS J1030+0524
R. Nanni, R. Gilli, C. Vignali +23
We present the results from a ks Chandra observation of the QSO SDSS J1030+0524. This is the deepest X-ray observation to date of a QSO. The QSO is dete…
LBT/MODS spectroscopy of globular clusters in the irregular galaxy NGC 4449
F. Annibali, E. Morandi, L. L. Watkins +11
We present intermediate-resolution (R1000) spectra in the 3500-10,000 A range of 14 globular clusters in the magellanic irregular galaxy NGC 4449 acquired with the Mult…
