Observational Astrophysics – Cosmology
Ground-Based Astrophysics
IAASARS researchers have expertise in ground-based observations with optical telescopes in both photometry and spectroscopy. They mainly address problems related to stars, their evolution and complex interplay with the ISM, as well as binary stars and stellar proper motion. In addition group members are studying the morphology and evolution of nearby galaxies.

X-ray Astrophysics
The X-ray Astrophysics group is one of the largest groups of the institute with four permanent staff and six postdoctoral researchers. The group has extensive experience in X-ray data analysis mainly from the XMM-Newton space observatory and also from the Chandra X-ray observatory. The group has been focusing problems related to AGN formation and evolution as it can be probed by the X-ray emission of distant and nearby galaxies.

Infrared Astrophysics
The Infrared Astrophysics group has a strong expertise in infrared data analysis obtained with the Spitzer Space Telescope of NASA and the Herschel Space Observatory and Infrared Space Observatory of ESA. The team addresses various topics in extragalactic astrophysics and in particular in galaxy evolution, dust formation and gas depletion in interacting galaxies and Active Galactic Nuclei, gas and dust properties of Luminous Infrared Galaxies, as well as radiative transfer modeling and dust properties of nearby galaxies.

Cosmology
The research activities in the fields of Theoretical and Observational Cosmology focus on the study of the Universe as a whole, from its primordial to its late-time era, and in particular on the following:
a) Accelerated expansion of the Universe
b) Dark Energy and Dark Matter
c) Primordial Universe (Big Bang, Inflation, Reheating, Phase Transitions, Baryogenesis, Nucleosynthesis, etc)
d) Matter Clustering and Large Scale Structure
e) Test of General Theory of Relativity at cosmological scales
f) Modified and Extended Theories of Gravity
g) Black Holes and Gravitational Waves
h) Cosmological Simulations
i) Elaboration of Cosmological Data (from Cosmic Microwave Background Radiation (CMB), Supernovae Type Ia (SNIa), Baryonic Acoustic Oscillations (BAO), Cosmic Chronometers (CC), Growth Index, Large Scale Structure (LSS), etc) in order to check cosmological scenarios and theories.
