On the basis of a recently updated data base of Sardinian Megalithic monuments, we perform two independent statistical analyses on several groups of these...
On the orientation of Roman cities in Hispania: preliminary results
Despite the fact that ancient writings indicate a clear necessity to orient Roman towns according to the path of the sun (Hyginus Gromatius, Constitutio, 1), Le...
On the origin and fate of ionised-gas in early-type galaxies: The SAURON perspective
By detecting ionised-gas emission in 75% of the cases, the SAURON integral-field spectroscopic survey has further demonstrated that early-type galaxies often...
On the origin of dwarf elliptical galaxies: the fundamental plane
Context: Early-type dwarf (dE) galaxies are the most common type of galaxies observed in the Universe. Their study has important cosmological implications...
On the Origin of Lopsidedness in Galaxies as Determined from the Spitzer Survey of Stellar Structure in Galaxies (S4G)
We study the m = 1 distortions (lopsidedness) in the stellar components of 167 nearby galaxies that span a wide range of morphologies and luminosities. We...
Galactic cirrus emission at far-infrared wavelengths affects many extragalactic observations. Separating this emission from that associated with extragalactic...
