The research interests of the group are focused on multi-wavelength observations and theoretical modeling of accreting sources, galaxies, supernova remnants, and the Ionized Intergalactic Medium.

We use data obtained with a wide suite of space obsevatories observing in X-ray, Ultraviolet, Optical and Infrared wavelengths. In addition we use data from ground-based optical and infrared facilities such as the Skinakas Observatory. The goal of these observations is: to understand the physical processes which produce the observed radiation, study the evolution of stellar systems and galaxies, and probe the baryonic content of the Universe.

The theoretical efforts of our group are focused on the radiation production mechanisms in accreting sources, the interaction between radiation and matter and the structure of galaxies.

• A comprehensive study with the Spitzer and Herschel Space Observatory of a flux limited sample of Luminous Infrared Galaxies (Dias-Santos et al, ApJ, 2014, 788, 17, Dias-Santos et al, ApJ, 2011, 741, 32; Dias-Santos et al, ApJ, 2010, 723, 993))

• Patterns of variability in Be/X-ray pulsars during giant outbursts (Reig, P. & Nespoli, E. 2013, A&A, 551, 1)

• The first measurement of the distance and density of a mildly ionized outflow in the nearby Seyfert 1 galaxy NGC 4051, which provided the first robust estimate of the mass outflow rates from such ionized outflows in AGNs ( Krongold et al., 2007, ApJ, 659, 1022)
