Satellite accretion events have been invoked for mimicking the internal secular evolutionary processes of bulge growth tep{Kormendy04}. In order to investigate...

Vertical instabilities, buckling, in stellar bars weaken and shorten the bar. This can interrupt the bar-induced gas inflow into the central kpc of a galaxy for...

The solar spectrophotometer "Mark-I", located at the Observatorio del Teide and continuously operated for the latest 36, provides a high precision measurement...

We compute UV to radio continuum spectral energy distributions of 51 nearby galaxies recently observed with SPIRE onboard Herschel and present infrared colours...

The quality of astronomical observations is strongly related to the quality properties of the atmosphere. This parameter is important for the determination of...

We present seeing measurements from Mt. Holomon (Chalkidiki, Greece), a possible site for the establishment of a new University of Thessaloniki Observatory...

We explore the possibility that the old and intermediate-age, populations within the Carina dwarf spheroidal galaxy exhibit distinct kinematic and chemical...

We present the star formation histories (SFHs) of four isolated dwarf galaxies, Cetus, Tucana, LGS-3, and Phoenix, as a function of galactocentric radius. Our...

Using a sample of 654 objects selected from the Sloan Digital Sky Survey (SEGUE) plates, we evaluated and adjusted the SDSS target algorithm for Blue Horizontal...
