Research

  • Stellar astrophysics, nucleosynthesis, mass loss and infrared astronomy:
    Last stages of stellar evolution, for low and intermediate mass stars. Nucleosynthesis and chemical evolution. Theoretical models and observation (especially in the infrared bands). Mass loss, dust and circumstellar envelopes of late-type red giants (AGB stars). Development of instrumentation suitable for infrared astronomy (mid-IR cameras for ground based telescopes, and the IRAIT telescope in particular).
       
  • IRAIT and infrared astronomy from Antarctica:
    Telescope adaptation for Antarctic conditions. Mechanics and telescope automatization. Control software for the telescope and the infrared camera. Infrared arrays. Performances simulation. Source catalogs. Mid-infrared surveys and stellar evolution. 
       
  • Blazars optical variability and high-energy emission:
    Optical monitoring of blazars variability with the 40cm Automatic Imaging Telescope (AIT) of the Perugia Observatory. Multiband photometry. Alert of blazars flares for high-energy satellites. Follows-up. Participation to multiwavelength observing campaigns (and international collaborations like the WEBT, and ENIGMA). Variability and time series analysis. Theoretical emission models for blazars. High-energy (e.g. gamma-ray) emission models. Multifrequency analysis.
         
  • GLAST and high-energy gamma-ray astrophysics:
    Collaboration with the INFN Perugia Section to GLAST. Electronic tests in clean room of single strip detectors and ladders of the LAT tracker. Mechanical and thermal tests. Observation simulator. Sources simulations and response functions of the instrument. Blazar gamma-ray emission models. Variability and time series analysis.  Gamma-ray bursts. Other techniques, like the independent component analysis and wavelets, suitable to extract sources from the background.
        
  • REM and gamma-ray bursts:
    ROSS development and control software. Remote control. Transient rapid pointing. Gamma-ray burst optical and near-infrared studies. Theoretical nucleosynthesis in progenitors, isotopes and GRB.
       
  • Stellar variability:
    Long period variable stars. Late-type red giants stars (eg. Mira type). Digitalization of archival optical plates. Short term variability in cataclysmic stars and dwarf novae.
