Structure of the SMC - Stellar component distribution from 2MASS data
I. Gonidakis, E. Livanou, E. Kontizas +5
The spatial distribution of the SMC stellar component is investigated from 2MASS data. The morphology of the different age populations is presented. The center of the distribution…
High-excitation molecular gas in local luminous AGN hosts
Padeli P. Papadopoulos, A. Kovacs, A. S. Evans +1
We used the mm/sub-mm receivers on the James Clerk Maxwell Telescope (JCMT) to observe the CO J=3--2, 2--1 lines in five local, optically powerful AGN and the J=4--3 line in 3C 293…
The X-ray variability and the near-IR to X-ray spectral energy distribution of four low luminosity Seyfert 1 galaxies
I. E. Papadakis, Z. Ioannou, W. Brinkmann +1
We present the results from a study of the X-ray variability and the near-IR to X-ray spectral energy distribution of four low-luminosity, Seyfert 1 galaxies. We compared their var…
The Environment of Sy1, Sy2 & Bright IRAS Galaxies
E. Koulouridis, V. Chavushyan, M. Plionis +4
We present a 3-dimensional study of the local (< 100 kpc) environment of Sy1, Sy2 and Bright IRAS Galaxies. For this purpose we use three galaxy samples (Sy1, Sy2, BIRG) located at…
X-ray selected AGN in groups at redshifts z~1
A. Georgakakis, Brian F. Gerke, K. Nandra +4
We explore the role of the group environment in the evolution of AGN at the redshift interval 0.7<z<1.4, by combining deep Chandra observations with extensive optical spectroscopy…
Could Dark Matter Interactions be an Alternative to Dark Energy ?
S. Basilakos, M. Plionis
We study the global dynamics of the universe within the framework of the Interacting Dark Matter (IDM) scenario. Assuming that the dark matter obeys the collisional Boltzmann equat…
