Recent planning for Constellation-X has driven the exploration of grazing incidence telescopes with focal lengths of 50 m or greater. Formation flying, wherein separate optic and detector spacecraft travel in formation, is one approach to implementing such long focal lengths. This approach eliminates the telescope tube that is an integral part of

We present the current status of definition of the observational and analysis strategies for the study of Active Galactic Nuclei (AGN) in the OTELO survey. The main goal of this project is to determine the fraction of each species of AGN and their luminosity functions.

We have started an observing program to study the whole sample of interaction systems from the Second Byurakan Survey (SBS) (around 20 sky fields) using a CCD camera and the B, R, and H α filters. The objectives of this project are: (1) to link the histories of the star formation and nuclear activity in these systems with the morphologic type of

Recently, Matthews et al. (2004, Nature, 430, 51) claim a null detection of p-mode oscillations in Procyon A from 32 days of nearly continuous photometric satellite-based observations (MOST). They did not even find evidence in the Fourier amplitude spectrum of Procyon of the uniform frequency spacing signature that solar-like stars acoustic

Starforming galaxies with compact morphology and high optical luminosity (LBCGs) are very common at redshitfs z = 0.4 - 1.2. Those galaxies are believed to have evolved more than other galaxy class during the last ~ 8 Gyr, and are a mayor contributor to the global star formation rate density of the universe at z ~ 1. A robust way to gauge their
