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
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
- Blazars optical variability and high-energy
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
Collaboration with the INFN Perugia Section to
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
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
