We have investigated the properties of the diffuse light in the Virgo Cluster core region, based on the detection of intracluster planetary nebulae (PNs) in...
Intracluster Stellar Population Properties from N-Body Cosmological Simulations. I. Constraints at z = 0
We use a high-resolution collisionless simulation of a Virgo-like cluster in a ΛCDM cosmology to determine the velocity and clustering properties of the diffuse...
Intrinsic and observed dual AGN fractions from major mergers
A suite of 432 collisionless simulations of bound pairs of spiral galaxies with mass ratios 1:1 and 3:1, and global properties consistent with the ΛCDM paradigm...
Intrinsic Colors and Ages of Extremely Red Elliptical Galaxies at High Redshift
In order to know the formation epoch of the oldest elliptical galaxies as a function of mass and observed redshift, a statistical analysis of 333 extremely red...
Intrinsic parameters of galactic luminous OB stars
We present the results of a spectroscopic analysis of 25 galactic luminous OB stars. The gravities are in general lower than previously assumed, especially for...
The Cherenkov Telescope Array (CTA) is a new observatory for very high-energy (VHE) gamma rays. CTA has ambitions science goals, for which it is necessary to...
Introducing the LBT Imaging of Galactic Halos and Tidal Structures (LIGHTS) survey. A preview of the low surface brightness Universe to be unveiled by LSST
We present the first results of the LBT Imaging of Galaxy Haloes and Tidal Structures (LIGHTS) survey. LIGHTS is an ongoing observational campaign with the 2 ×...
Inversion equation for the study of circumstellar dust shells - Application to Beta Pictoris
For circumstellar systems with an orientation perpendicular to the plane of the sky, and under some simplifying assumptions, the surface brightness integral...
Inversion of stellar statistics equation for the Galactic bulge
A method based on Lucy's iterative algorithm is developed to invert the equation of stellar statistics for the Galactic bulge and is then applied to the K-band...
