Euclid Collaboration, L. Pizzuti, G. Y. Ferron +304
We study the shape of three-dimensional and projected dark-matter halo profiles extracted from cosmological -body simulations in CDM and non-standard cosmologies, using the \…
Evolution of Virial Clouds - II: From the Formation of First Stars up to their Explosion
Noraiz Tahir, Asghar Qadir, Francesco De Paolis +1
The existence of cold gas and dust clouds close to the cosmic microwave background (CMB) temperature was proposed as a potential repository for a significant fraction of the missin…
Simulation of the spin evolution of some selected exoplanets and inferences on their climate
Salvatore Camposeo, Francesco De Paolis, Vincenzo Orofino +2
In this work, using the simulator VPLanet, we analyze the spin evolution of some selected exoplanets due to the tidal interaction with their host star. For a rocky planet, two spin…
Revisiting a Quasar Microlensing Event Towards AGN~J1249+3449
Mario Cazzolla, Francesco De Paolis, Antonio Franco +1
The gravitational wave event GW190521 seems to be the only BH merger event possibly correlated with an electromagnetic counterpart, which appeared about 34 days after the GW event.…
Timing analysis of a sample of five cataclysmic variable candidates observed by the XMM-Newton satellite
A. A. Nucita, S. M. Lezzi, F. De Paolis +4
Intermediate polars are a class of cataclysmic variables in which a white dwarf accretes material from a companion star. The intermediate polar nature confirmation usually derives…
COSMIC-S: a photometric Catalogue of Observed Stars in the Small MagellanIc Cloud
A. Franco, A. A. Nucita, F. De Paolis +1
The Dark Energy Camera (DECam) is a wide-field instrument mounted on the 4m V. Blanco Telescope (CTIO). Its impressive technical characteristics makes it one of the most suitable g…
Evidence of a sub-solar star in a microlensing event toward the LMC
