We studied the nuclear obscuration of galaxies hosting Low Ionization Narrow Emission Regions (LINERs) based on their X-ray and optical emission. X-ray data...
Obscured stellar clusters and nuclear activity in seyfert galaxies
Starbursts and AGNs are frequently coupled in the central kiloparsecs of seyfert galaxies, where molecular gas plays a critical role in fueling nuclear...
Observability and Geometry in Three Dimensional Quantum Gravity
We consider the coupling between massive and spinning particles and three dimensional gravity. This allows us to construct geometric operators (distances...
We study a family of physical observable quantities in quantum gravity. We denote them W functions, or n-net functions. They represent transition amplitudes...
Observation and analysis of chromospheric magnetic fields .
The solar chromosphere is a vigorously dynamic region of the sun, where waves and magnetic fields play an important role. To improve chromospheric diagnostics...
Observation and Upper Limits of GRBs with the MAGIC Telescope
After three years since the beginning of operation, the MAGIC telescope could observe several GRB events in the prompt and early afterglow phase. Thanks to its...
