Patrimonio culturale pubblico: alcune riflessioni sulla sua valutazione e sul ruolo dell'informazione (Public cultural property: Some reflections on its evaluation and the role of information.)

Moneta e Credito, 2012
Thepaper firstly deals with the main theories of prices of visual art goods considering, in particular, the "stars", whose high value reflects the rarity and the convexity of the demand by the main purchasers, interested in "famous" goods.

Discovery of the Closest Ultra-stripped Supernova: SN 2021agco in UGC 3855

The Astrophysical Journal Letters, 2023
We present the discovery and studies of the helium-rich, fast-evolving supernova (SN) 2021agco at a distance of ∼40 Mpc. Its early-time flux is found to rise from half peak to the peak of −16.06 ± 0.42 mag in the r band within ${2.4}_{-1.0}^{+1.5}$ days,

Ages and metallicities of five intermediate-age star clusters projected towards the Small Magellanic Cloud [PDF]

Mon.Not.Roy.Astron.Soc. 325 (2001) 792, 2001
Colour-magnitude diagrams are presented for the first time for L32, L38, K28 (L43), K44 (L68) and L116, which are clusters projected onto the outer parts of the Small Magellanic Cloud (SMC). The photometry was carried out in the Washington system $C$ and $T_1$ filters allowing the determination of ages by means of the magnitude difference between the ...

The infrared luminosity of the torus and the visibility of scattered broad line emission in Seyfert 2 galaxies [PDF]

Mon.Not.Roy.Astron.Soc. 328 (2001) L32, 2001
A number of studies have shown that the visibility of scattered broad emission lines in Seyfert 2 galaxies is strongly dependent on the IRAS f_60/f_25 flux ratio, where those Seyfert 2s with `warm' IRAS colours show polarised broad line emission. It is now clear that this effect is due to the increasing dominance of the galactic rather than the AGN ...

The differential equation satisfied by a plane curve of degree n [PDF]

, 2006
Eliminating the arbitrary coefficients in the equation of a generic plane curve of order $n$ by computing sufficiently many derivatives, one obtains a differential equation. This is a projective invariant. The first one, corresponding to conics, has been

Detection of non-Gaussian Signatures in the VIRMOS-DESCART Lensing Survey [PDF]

Astron.Astrophys. 389 (2002) L28-L32, 2002
We have detected non-Gaussian signatures in the VIRMOS-DESCART weak lensing survey from a measurement of the three-point shear correlation function, following the method developed by Bernardeau et al. (2002). We obtain a 2.4-sigma signal over four independent angular bins, or equivalently, a 4.9-sigma confidence level detection with respect to ...

Higher-Spin Gauge Fields Interacting with Scalars: The Lagrangian Cubic Vertex

, 2007
We apply a recently presented BRST procedure to construct the Largangian cubic vertex of higher-spin gauge field triplets interacting with massive free scalars.

Discovery of a Possible Anomalous X-ray Pulsar in the Small Magellanic Cloud [PDF]

Astrophys.J.574:L29-L32,2002; Addendum-ibid.599:L115-L116,2003, 2002
We report the serendipitous detection of a previously unreported pulsar from the direction of the Small Magellanic Cloud using data from the CHANDRA X-Ray Observatory. Because of the luminosity of about 1.5x10^35 ergs/s, its near lack of variability for more than 20 years, and its soft spectrum we propose that it is an anomalous X-ray pulsar (AXP ...
