SN 2009E: a faint clone of SN 1987A [PDF]

open access: yes, 2011
In this paper we investigate the properties of SN 2009E, which exploded in a relatively nearby spiral galaxy (NGC 4141) and that is probably the faintest 1987A-like supernova discovered so far.

The GAPS programme with HARPS-N@TNG IV: A planetary system around XO-2S [PDF]

open access: yes, 2014
We performed an intensive radial velocity monitoring of XO-2S, the wide companion of the transiting planet-host XO-2N, using HARPS-N at TNG in the framework of the GAPS programme.

NIR Follow-Up of the VVDS 02hr Field [PDF]

open access: yes, 2006
We present a new K-band survey covering 623 arcmin$^2$ in the VVDS 0226-0430 deep field down to a limiting magnitude K$_{\rm{Vega}}$ $\leq$ 20.5. We use the spectroscopic sample extracted from this new K-band catalogue to assess the effectiveness of ...

Neutral Iron Emission Lines From The Day-side Of KELT-9b -- The GAPS Programme With HARPS-N At TNG XX [PDF]

open access: yes, 2020
We present the first detection of atomic emission lines from the atmosphere of an exoplanet. We detect neutral iron lines from the day-side of KELT-9b (Teq $\sim$ 4, 000 K).

SN 2002lt and GRB 021211: a SN/GRB Connection at z = 1 [PDF]

open access: yes, 2003
We present spectroscopic and photometric observations of the afterglow of GRB 021211 and the discovery of its associated supernova, SN 2002lt. The spectrum shows a broad feature (FWHM = 150 A), around 3770 A (in the rest-frame of the GRB), which we ...

SN 2005cs in M51 I. The first month of evolution of a subluminous SN II plateau [PDF]

open access: yes, 2006
Early time optical observations of supernova (SN) 2005cs in the Whirlpool Galaxy (M51), are reported. Photometric data suggest that SN 2005cs is a moderately under-luminous Type II plateau supernova (SN IIP).

Exact Time: the First Scientific Application of Radiocommunications

open access: yesSubstantia, 2018
Marconi’s first experiment of signal transmission by means of Hertzian waves was carried out in 1895. In the following years, wireless telegraphy progressed steadily and worldwide efforts were made to exploit the potential offered by new technologies. In

HST Imaging of Star-forming Clumps in Six GASP Ram-pressure-stripped Galaxies

open access: yesThe Astrophysical Journal, 2023
Exploiting broad- and narrowband images of the Hubble Space Telescope from the near-UV to I -band rest frame, we study the star-forming clumps of six galaxies of the GASP sample undergoing strong ram pressure stripping.
